Definitions
- This invention pertains to a run flat tire insert system for a transport tire.
- the present invention is in a tire insert system for fitting into a tire, such as an automobile or truck tire.
- the insert is formed into a ring, preferably from four sections, that are fitted together into a ring within a tire during the process of mounting the tire on a wheel.
- Which wheel is formed from front and rear sections, with the rear section preferably including a wheel web and a flange and includes a foot section that is for coupling to the wheel front section, forming the wheel that will hold and maintain a tire containing the ring insert at the tire beads.
- the tire insert is assembled from tire insert segments that are each fitted into the tire during the mounting of the tire on the wheel, with the insert segments each for mounting, at aligned holes in the front and rear wheels, with the same nut and bolt used for each mounting hole, securing a tire insert anchor plate sandwiched between the wheel front and rear sections.
- Which tire contains the assembled ring shaped tire insert and the tire beads are fitted across the wheel front and rear sections, with the tire beads held behind each of the wheel flanges ends. So arranged, bolts that receive nuts turned thereover are fitted through the aligned holes in the wheel front and rear sections and tire insert anchor plate, sandwiching the four insert anchor plates therebetween, completing the wheel mounting of the tire wherein the assembled ring of tire inserts is maintained.
- the tire insert system of the invention is assembled from four section in end to end butting arrangement, forming a ring within the tire and each insert anchor plate is secured between the wheel and rear sections so as to forming a continuous ring within the wheel that mounts the tire, allowing the clearance between the assembled ring outer surface and the tire inner surface to be close fitting.
- earlier insert arrangements like those found in run flat tires of major tire manufacturers, have been formed as closed or continuous rings and with the ring having to be fitted into the tire by fitting one section of the ring insert into the tire and pulling the other section of the ring insert across the tire bead and into the tire.
- the earlier insert radius has to be significantly smaller than the radius of the tire inner surface, under the tread. So arranged, with the earlier continuous ring insert installed in a tire, there will exist a space that can be a significant spacing distance for a typical run flat tire. Accordingly, in practice, should a tire with such continuous ring insert go flat, and the tread undersurface collapse into engagement with the earlier ring top surface, the tire sides walls will be deeply folded.
- Such flat tire when operated at only fifty miles an hour or less, will, because of the deep side wall folds, experience flexure in its side wall as it rolls under load that rapidly and heat the tire to, in short order, cause the tire to overheat and begin to fall apart.
- Such tire with a continuous ring insert will therefore only travel a few miles, and usually not more than around fifty miles, before it falls apart, stranding the car and driver.
- the present invention provides a tire insert that is assembled into a ring during its fitting into the tire, allowing the formed ring to have a radius that is just smaller than the radius of the pressurized tire inner surface under load. Thereby, should the tire lose pressure, the tire side walls will be only slightly bent when the tire inner surface engages that insert surface. This means that less sidewall flexure will occur as the tire rolls under load, generating less heat, and providing a run flat tire having a longer life than other run flat tires when it is run flat under load.
- U.S. Pat. No. 6,679,306 shows a tire with an inner support fitted therein for taking up a load upon outer tire deflation.
- the inner support of this patent is itself a tire that, by its construction, is load bearing at atmospheric conditions and will therefore support the load on an outer air filled tire should that air be lost.
- the '306 patent is unlike the invention in that it does not involve solid insert segments that are fitted in the tire during the tire mounting on a two piece rim.
- Another object of the present invention is to provide a tire insert ring that is formed from multiple segments, preferably four segments, that each make up a section of the ring, and where each tire insert segment is secured to an anchor plate that has a mounting surface for sandwiching between front and rear sections of a wheel.
- Another object of the present invention is to provide a front wheel section having a series of radial holes formed at equal spaced distances around its surface, below a wheel front flange, that will align with holes formed through the assembled insert anchor plates and through holes formed through a rear wheel section, and which aligned holes receive bolts that receive nuts turned thereover forming a wheel with tire insert sections that form a ring shaped outer surface that is positioned in the tire.
- Another object of the present invention is to provide a wheel for mounting the tire insert of the invention that is formed in front and rear sections to both mount anchor plate arcuate end portions of a plurality of tire insert segments, forming a ring shaped insert that is maintained within a tire whose beads are contained by opposing flanges of the assembled wheel front and rear sections, and which wheel and tire insert assembly occur together.
- Another object of the present invention is to provide tire insert segments arranged for coupling together edge to edge into a ring within the tire during wheel assembly where anchor plates of each insert are mounted, in side by side relationship, to a front wheel section, during the process of mounting the tire to the wheel front and rear sections.
- Another object of the present invention is to provide four tire insert segments that, when assembled together in end to end relationship, around the wheel front section, form a ring located that is located within a tire whose beads are fitted between wheel flanges of the respective front and rear wheel sections, where the insert tire segments under surfaces nesting across the wheel web.
- Still another object of the present invention is to provide a run flat tire insert system formed from a plurality of radial tire insert segments that are for joining end to end into a tire insert ring during the tire beads mounting between flange ends of front and rear wheel sections, where the tire insert sections anchor plates extend radially inwardly from the tire insert bottoms and are mounted around the front wheel section, between the wheel front and rear sections.
- Still another object of the present invention is to provide a run flat tire insert ring formed from separate tire insert segments from a selected elastomeric material to have a desired resiliency that will support and rebound a tire under load that contains the insert ring should the tread of that tire be deflected into the insert ring as by the tire running over an object, such as a rock or curb.
- Still another object of the present invention is to provide run flat tire insert system where the tire insert segments are manufactured in arcuate sections for fitting into, forming a continuous ring, and are fitted in the tire during tire mounting between front and rear wheel sections, where each tire insert has an arcuate outer surface, that when fitted together end to end with other insert segments form a continuous ring, and each tire insert is preferably formed by casting methods to incorporate an anchor plate that is bent at approximately a right angle to extend from the tire insert segment undersurface, and which anchor plate is to be fitted together with other anchor plates forming a disk that is open across its center and includes spaced holes formed at intervals therearound that are at like radial distances from the center of the opening and which tire insert anchor plates each have holes that are for aligning with holes formed through the wheel front and rear sections and receive bolts fitted therethrough.
- Still another object of the present invention is to provide wheel front and rear sections having aligned holes for joining the sections into a wheel with opposing wheel flanges and a web section therebetween, and which aligned holes also align with each of the insert anchor plate holes that, along with the wheel front and rear section holes, receive bolts fitted therethrough for maintaining the assembled insert ring to the wheel with the insert ring positioned within a tire whose bead ends are maintained between the wheel flanges.
- Still another object of the present invention is to provide a run flat tire insert system that is to be fitted into a tire during the tire mounting process to have its top surface spaced a selected distance from the undersurface of the tire tread so as to provide a minimum tire side wall flexure should air be lost from the tire during operation causing the tire collapse onto the insert ring top surface, minimizing heat build up at the tire side walls from tire side wall flexure, so as to allow a vehicle to travel a significant distance and speed after the tire has gone flat.
- Still another object of the present invention is to provide a run flat tire insert system that can be easily mounted in a tire during the process of mounting the tire onto a wheel having front and rear sections, and where the tire insert can be easily dismounted from a worn tire and refitted into a new tire.
- the present invention is in a tire insert system for mounting to a wheel whereto is mounted a tire, with the tire insert system to fit into the tire mounted on that wheel.
- the tire insert system includes individual arcuate shaped outer bars formed from an elastomeric material, that is preferably a mixture of urethane material constituents. Which urethane constituents are selected to have a desired hardness so as to support a tire tread under a load collapsed thereon by the deflation of the tire, and yet will still provide some resiliency to cushion the tire inner surface and promote its rebounding off of the insert surface should the tire, while still under air pressure, strike an object, to deflect the tire tread undersurface onto the tire insert outer surface.
- the tire insert assembly is formed in a plurality of sections, preferably four sections, that are fitted together into a ring shape.
- Each tire insert is fixed onto a disk mounting plate that is at approximately a right angle to the tire insert undersurface and is for mounting to a wheel that is assembled from front and rear wheel sections that, when assembled together, form the wheel for mounting onto an axle at a hub section, that includes flanges separated by a flange web.
- Which wheel flanges opposing surfaces each receive a tire bead fitted thereagainst whereby, when air is introduced into the tire, the tire will expand and forces the beads into sealing engagement with the flanges opposing surfaces, locking the tire between the wheel flanges.
- the tire inserted segment are preferably arch shaped castings where a right angle top end of each of the tire insert segment anchor plates are aligned in a mold that receives a pour of urethane material that, when cured, encapsulates each tire insert segment anchor plate right angle end in the arch shaped tire insert segment, providing a permanent coupling of the tire insert segment components for convenient fitting into a tire during the wheel assembly and the mounting of the tire to the wheel.
- Which tire insert segment anchor plates right angle ends are preferably somewhat curved and may, to increase the bonding area, have corrugations or other angle bends, formed therein for increasing the bond area.

Description
- 1. Field of The Invention
- This invention pertains to a run flat tire insert system for a transport tire.
- 2. Prior Art
- The present invention is in a tire insert system for fitting into a tire, such as an automobile or truck tire. The insert is formed into a ring, preferably from four sections, that are fitted together into a ring within a tire during the process of mounting the tire on a wheel. Which wheel is formed from front and rear sections, with the rear section preferably including a wheel web and a flange and includes a foot section that is for coupling to the wheel front section, forming the wheel that will hold and maintain a tire containing the ring insert at the tire beads. The tire insert is assembled from tire insert segments that are each fitted into the tire during the mounting of the tire on the wheel, with the insert segments each for mounting, at aligned holes in the front and rear wheels, with the same nut and bolt used for each mounting hole, securing a tire insert anchor plate sandwiched between the wheel front and rear sections. Which tire contains the assembled ring shaped tire insert and the tire beads are fitted across the wheel front and rear sections, with the tire beads held behind each of the wheel flanges ends. So arranged, bolts that receive nuts turned thereover are fitted through the aligned holes in the wheel front and rear sections and tire insert anchor plate, sandwiching the four insert anchor plates therebetween, completing the wheel mounting of the tire wherein the assembled ring of tire inserts is maintained.
- The tire insert system of the invention is assembled from four section in end to end butting arrangement, forming a ring within the tire and each insert anchor plate is secured between the wheel and rear sections so as to forming a continuous ring within the wheel that mounts the tire, allowing the clearance between the assembled ring outer surface and the tire inner surface to be close fitting. Whereas, earlier insert arrangements, like those found in run flat tires of major tire manufacturers, have been formed as closed or continuous rings and with the ring having to be fitted into the tire by fitting one section of the ring insert into the tire and pulling the other section of the ring insert across the tire bead and into the tire. Accordingly, to allow the ring insert of earlier tire inserts to be pulled across the tire inelastic bead, the earlier insert radius has to be significantly smaller than the radius of the tire inner surface, under the tread. So arranged, with the earlier continuous ring insert installed in a tire, there will exist a space that can be a significant spacing distance for a typical run flat tire. Accordingly, in practice, should a tire with such continuous ring insert go flat, and the tread undersurface collapse into engagement with the earlier ring top surface, the tire sides walls will be deeply folded. Such flat tire, when operated at only fifty miles an hour or less, will, because of the deep side wall folds, experience flexure in its side wall as it rolls under load that rapidly and heat the tire to, in short order, cause the tire to overheat and begin to fall apart. Such tire with a continuous ring insert will therefore only travel a few miles, and usually not more than around fifty miles, before it falls apart, stranding the car and driver.
- The present invention provides a tire insert that is assembled into a ring during its fitting into the tire, allowing the formed ring to have a radius that is just smaller than the radius of the pressurized tire inner surface under load. Thereby, should the tire lose pressure, the tire side walls will be only slightly bent when the tire inner surface engages that insert surface. This means that less sidewall flexure will occur as the tire rolls under load, generating less heat, and providing a run flat tire having a longer life than other run flat tires when it is run flat under load.
- Like the present invention, an earlier run flat tire of one of the applicants, U.S. Pat. No. 6,679,306, shows a tire with an inner support fitted therein for taking up a load upon outer tire deflation. The inner support of this patent, however, is itself a tire that, by its construction, is load bearing at atmospheric conditions and will therefore support the load on an outer air filled tire should that air be lost. The '306 patent, however, is unlike the invention in that it does not involve solid insert segments that are fitted in the tire during the tire mounting on a two piece rim. Additionally, where some earlier U.S. Pat. Nos. 3,250,310; 3,814,158; 4,246,948; and 5,341,861, have shown support rings or auxiliary wheels inside and enclosed by a tire and rim, such, unlike the present invention, have been continuous ring members, or as in the case of the '861 patent have included bolt members that can be turned through the wheel web to extend actuator head ends into the tire to, apparently, engage and support the tire surface under the tread should the tire deflate. None of which arrangements are like the invention where tire insert sections are assembled within the tire, forming the insert ring, during the mounting to the tire on the wheel.
- It is a principal object of the present invention to provide a tire insert system formed in sections for assembly within a tire during mounting of the tire onto a wheel to provide a run flat capability to that tire.
- Another object of the present invention is to provide a tire insert ring that is formed from multiple segments, preferably four segments, that each make up a section of the ring, and where each tire insert segment is secured to an anchor plate that has a mounting surface for sandwiching between front and rear sections of a wheel.
- Another object of the present invention is to provide a front wheel section having a series of radial holes formed at equal spaced distances around its surface, below a wheel front flange, that will align with holes formed through the assembled insert anchor plates and through holes formed through a rear wheel section, and which aligned holes receive bolts that receive nuts turned thereover forming a wheel with tire insert sections that form a ring shaped outer surface that is positioned in the tire.
- Another object of the present invention is to provide a wheel for mounting the tire insert of the invention that is formed in front and rear sections to both mount anchor plate arcuate end portions of a plurality of tire insert segments, forming a ring shaped insert that is maintained within a tire whose beads are contained by opposing flanges of the assembled wheel front and rear sections, and which wheel and tire insert assembly occur together.
- Another object of the present invention is to provide tire insert segments arranged for coupling together edge to edge into a ring within the tire during wheel assembly where anchor plates of each insert are mounted, in side by side relationship, to a front wheel section, during the process of mounting the tire to the wheel front and rear sections.
- Another object of the present invention is to provide four tire insert segments that, when assembled together in end to end relationship, around the wheel front section, form a ring located that is located within a tire whose beads are fitted between wheel flanges of the respective front and rear wheel sections, where the insert tire segments under surfaces nesting across the wheel web.
- Still another object of the present invention is to provide a run flat tire insert system formed from a plurality of radial tire insert segments that are for joining end to end into a tire insert ring during the tire beads mounting between flange ends of front and rear wheel sections, where the tire insert sections anchor plates extend radially inwardly from the tire insert bottoms and are mounted around the front wheel section, between the wheel front and rear sections.
- Still another object of the present invention is to provide a run flat tire insert ring formed from separate tire insert segments from a selected elastomeric material to have a desired resiliency that will support and rebound a tire under load that contains the insert ring should the tread of that tire be deflected into the insert ring as by the tire running over an object, such as a rock or curb.
- Still another object of the present invention is to provide run flat tire insert system where the tire insert segments are manufactured in arcuate sections for fitting into, forming a continuous ring, and are fitted in the tire during tire mounting between front and rear wheel sections, where each tire insert has an arcuate outer surface, that when fitted together end to end with other insert segments form a continuous ring, and each tire insert is preferably formed by casting methods to incorporate an anchor plate that is bent at approximately a right angle to extend from the tire insert segment undersurface, and which anchor plate is to be fitted together with other anchor plates forming a disk that is open across its center and includes spaced holes formed at intervals therearound that are at like radial distances from the center of the opening and which tire insert anchor plates each have holes that are for aligning with holes formed through the wheel front and rear sections and receive bolts fitted therethrough.
- Still another object of the present invention is to provide wheel front and rear sections having aligned holes for joining the sections into a wheel with opposing wheel flanges and a web section therebetween, and which aligned holes also align with each of the insert anchor plate holes that, along with the wheel front and rear section holes, receive bolts fitted therethrough for maintaining the assembled insert ring to the wheel with the insert ring positioned within a tire whose bead ends are maintained between the wheel flanges.
- Still another object of the present invention is to provide a run flat tire insert system that is to be fitted into a tire during the tire mounting process to have its top surface spaced a selected distance from the undersurface of the tire tread so as to provide a minimum tire side wall flexure should air be lost from the tire during operation causing the tire collapse onto the insert ring top surface, minimizing heat build up at the tire side walls from tire side wall flexure, so as to allow a vehicle to travel a significant distance and speed after the tire has gone flat.
- Still another object of the present invention is to provide a run flat tire insert system that can be easily mounted in a tire during the process of mounting the tire onto a wheel having front and rear sections, and where the tire insert can be easily dismounted from a worn tire and refitted into a new tire.
- The present invention is in a tire insert system for mounting to a wheel whereto is mounted a tire, with the tire insert system to fit into the tire mounted on that wheel. The tire insert system includes individual arcuate shaped outer bars formed from an elastomeric material, that is preferably a mixture of urethane material constituents. Which urethane constituents are selected to have a desired hardness so as to support a tire tread under a load collapsed thereon by the deflation of the tire, and yet will still provide some resiliency to cushion the tire inner surface and promote its rebounding off of the insert surface should the tire, while still under air pressure, strike an object, to deflect the tire tread undersurface onto the tire insert outer surface.
- The tire insert assembly is formed in a plurality of sections, preferably four sections, that are fitted together into a ring shape. Each tire insert is fixed onto a disk mounting plate that is at approximately a right angle to the tire insert undersurface and is for mounting to a wheel that is assembled from front and rear wheel sections that, when assembled together, form the wheel for mounting onto an axle at a hub section, that includes flanges separated by a flange web. Which wheel flanges opposing surfaces each receive a tire bead fitted thereagainst whereby, when air is introduced into the tire, the tire will expand and forces the beads into sealing engagement with the flanges opposing surfaces, locking the tire between the wheel flanges. To provide for wheel assembly, holes in upper portions of the respective wheel front and rear sections are coupled together, sandwiching the tire insert anchor plates therebetween, as by fitting bolts through aligned holes in each of the upper portions that nuts are turned onto. Which upper portions, prior to fitting bolts therethrough receive the tire insert anchor plates fitted therebetween that have holes formed therethrough to receive the bolts fitted through the wheel sections upper portion holes, coupling the components together to receive the nuts tightened thereon, mounting the tire insert segments anchor plates in side by side relationship, forming the tire insert ring. Which assembly includes the fitting of each tire insert segments into the tire, forming the insert ring with the disk shaped anchor plates fitted together as a ring with an open center, for sandwiching between the wheel front and rear sections. In which tire insert segment assembly and anchor plate coupling into the wheel, the assembled tire insert inner circumference is snugly fitted to the web surface between the wheel flanges.
- The tire inserted segment are preferably arch shaped castings where a right angle top end of each of the tire insert segment anchor plates are aligned in a mold that receives a pour of urethane material that, when cured, encapsulates each tire insert segment anchor plate right angle end in the arch shaped tire insert segment, providing a permanent coupling of the tire insert segment components for convenient fitting into a tire during the wheel assembly and the mounting of the tire to the wheel. Which tire insert segment anchor plates right angle ends are preferably somewhat curved and may, to increase the bonding area, have corrugations or other angle bends, formed therein for increasing the bond area.
- While the tire insert segments can be of like arches of approximately ninety degrees each, it is preferred that the top and bottom segments are of less arch than the arch of the side segments, facilitating their fitting into the tire, in side by side position, forming the ring shaped tire insert within the tire, and with the anchor plates forming a disk that is open across its middle area.
- The invention may take physical form in certain parts and arrangement of parts, that are used to form the apparatus of and practice the steps of the assembly of the invention into a run flat tire insert that are herein shown as a preferred embodiment and will be described in detail in this specification and illustrated in the accompanying drawings which form a part hereof:
-

FIG. 2 shows a side elevation perspective view like that ofFIG. 1 only taken from the front of the assembled tire insert segments; -
FIG. 3 shows an enlarged side elevation view of the assembled tire insert segments; -
FIG. 4 shows a view like that ofFIG. 3 only showing the tire insert segments as having been exploded apart; -
FIG. 5 shows an end elevation view of the tire insert segments assembled into a ring; -
FIG. 6 shows an end sectional view taken along the line 6-6 ofFIG. 3 ; and -
FIG. 7 shows the sectional view ofFIG. 6 that further includes a sectional view of a tire mounted between wheel flanges and includes the tire insert segments assembled into a ring and contained in the mounted tire. - The invention is in a tire insert system that is shown assembled in
FIGS. 1 and 2 into atire insert ring 10 that is for assembly in a tire, that is mounted onto awheel 34, as illustrated inFIG. 7 . Thetire insert ring 10 is shown in a profile perspective view, taken from the rear thereof, inFIG. 1 , and as a profile perspective view, taken from the front thereof inFIG. 2 . As shown, thetire insert ring 10 is formed from arcuate segments, and the Figs. show four separate arcuate segments as making up acomplete insert ring 10. It should, however, be understood that as few as two arcuate segments are required to form thetire insert ring 10, and so a greater number than two arcuate segments could be so used to form thetire insert ring 10, within the scope of this disclosure. -
FIGS. 1 and 2 show four tire insert segments that have been fitted together to form thetire insert ring 10. Which tire insert ring includes a first pair ofinsert segments 11 that are each of like arcuate shape, are arranged across from one another around the ring and are smaller in arch than a second pair oftire insert segments 12 than are each of a like arcuate shape and are also arranged across from one another. In practice, thetire insert segments 11 each have an arc at their outer curved surface of approximately thirty five (35) degrees and each of thetire insert segments 12 has an arc of approximately one hundred forty five (145) degrees, but which arch relationship can be varied so long as the total of the arcs of the four segments is three hundred sixty (360) degrees. Thetire insert segments tire insert ring 10. In that assembly,anchor plates tire insert segments anchor plates flat ring disk 15 that is open across its center area. The assembledanchor plates flat ring disk 15, as shown, includes equal spacedholes 16 formed through the flat ring disk that are for receiving fasteners, such bolts with nuts turned there-over, for coupling to a wheel that is assembled from front and rear wheel sections, as set out and described below. -
FIG. 3 shows a front elevation view of thetire insert 10 ofFIGS. 1 and 2 that includes the individualtire insert segments tire insert ring 10, and showing theanchor plates flat disk 15 that is open across its center and wherein the spacedholes 16 are formed.FIG. 3 illustrates the assembled runflat tire insert 10 as it appears fitted into a tire, like thetire 34 shown inFIG. 7 . -
FIG. 4 shows an exploded view of thetire insert 10 ofFIG. 3 , that illustrates how thetire insert segments anchor plates FIG. 7 . -
FIG. 5 shows a profile file of the assembledtire insert 10, showing thesmaller arc segments 11 on the top and bottom, respectively, and thelarger arc segment 12 on a forward face of the ring shapedinsert 10. Thetire insert 10 is shown as being essentially flat across itsouter surface 17, that, as shown inFIG. 7 , is the contact atire 30 inner surface around itscircumference 61, below atire tread 62. So arranged, should thetire 30 deflate, the tireinner surface 61 will engage, and be supported on, thetire insert 10. As shown inFIG. 6 , to enhance the load supporting ability of thetire insert 10 the insert sides 18 are each slightly tapered outwardly and are stepped outwardly and end at astep 19, that ends insides walls section 21 that ends in abase section 22 that extends, as shown inFIGS. 6 and 7 , across the tire insert and ends at a junction with a lower end of theside wall 20 b. Which base section is contoured into a wheel flange web, and it of greater width than the width of thetire insert 10 across itstop surface 17. The tapering of the tire insert sides provides for an efficient load force transmission through thetire insert 10 and into aweb 43 of awheel 34, as shown inFIG. 7 . Thetire insert 10 is stepped fromcomers 18 a outwardly intosteps 19, with thesteps 19 form approximately a right angle bend to theside walls side wall 20 a on the inside side of the wheel and tire is sloped inwardly at 21, terminating at the end of an essentially flatinsert base section 22 whoseopposite end 23 a slopes downwardly into a contouredsection 23 that then slopes outwardly at 24, forming a pier that, in turn, slopes upwardly as asloped section 25. Which contours of the tire insert bottom surface allow it to fit snugly onto thewheel 34web 43, as shown inFIG. 7 . So arranged, thetire insert 10 undersurface ofFIG. 6 , closely fitted onto thewheel 34web 43, provides for evenly distributing a load transferred from thetire insert top 17, through the insert sides 18 and into thewheel 34. - The
tire insert 10 includes theinsert segments FIG. 1 through 5, for assembly together, in side by side relationship, forming thetire insert 10, that includes theanchor plates anchor plates center ring disk 15.FIG. 6 and 7 show sectional views of thetire insert segment 12 andanchor plate 14 of thetire insert ring 10, and show theanchor plate 14 as extending out of the tire insert contouredsection 23 as aflat section 30 from alower end 31 thereof, that is just below the spacedradial holes 16 formed therethrough, and has atop end 32 that is bent at an angle of from ten (10) to thirty (30) degrees into asupport section 33 within the tire insert. Whichanchor plate 14 from just below the benttop end 32, and across thesupport section 33, to itsend 33 a, is encapsulated in thetire insert segment 14. In practice, theanchor plates center ring disk 15 and have spacedholes 16 that receive fasteners, preferablybolts 50. Whichbolts 50 are individually fitted throughinsert mounting holes 36 that are formed through aleg 42 of the inner or backwheel section 35, and then through, the flat opencenter ring disk 15hole 16. With eachbolt 50 is then passed through aradial hole 41 that is formed through an upper portion of a forward orfront wheel section 40, and thebolt 50 thread end receives anut 51, as shown inFIG. 7 , turned thereon, securing the wheel rear andfront sections flat ring disk 15 of thetire insert 10 sandwiched therebetween. The wheel back andfront sections flat ring disk 15 at theanchor plates - The
wheel 34, as shown inFIG. 7 , is formed from the two rear andfront wheel sections rear wheel section 35 includes the spacedinsert mounting holes 36 that are each an equal radial distance out from an end of aleg 42. Thefront wheel section 40 includes acenter section 37 with spaced lug bolt holes 38 formed therethrough, above an open hub area, and tireinsert mounting holes 41 above thefront section 40. Above the tireinsert mounting holes 41 the wheel front section is bent into an end of awheel web 38 and terminates in aforward wheel flange 39. Whichwheel web end 38 andweb flange 39. The back orrear wheel section 35, that is connected to the front wheel section at theleg 42, includesweb 43 and aflange 44, forming the wheel whereto thetire insert 10 andtire 30 is mounted. - In which
tire insert 10 andtire 30 mounting ontowheel 34, as shown inFIG. 7 , thefront wheel section 40flange 39 is fitted over thetire 30bead 63 and eachtire insert section tire insert ring 10. In whichtire insert ring 10 formation, the tireinsert anchor plates insert mounting holes 41 of the front wheel section are aligned with the open disk holes 16. Therear wheel section 35flange 44 is then fitted onto thetire bead 63 and urged into engagement with the tire insert anchor plates, with theholes 36 inleg 42 aligning with the anchor plate andfront wheel section 40holes Bolts 50 are then fitted through the alignedholes nuts 51 are turned thereover, pullingtire 30beads 63 together at thewheel section flanges tire insert sections insert 10. So arranged, tighteningnut 51 ontobolt 50 pulls the rear andfront wheel sections anchor plate ring 15 sandwiched therebetween. Thewheel 34 mounting thetire 30 land containing the assembledtire insert ring 10 can thereafter, as shown inFIG. 7 , be mounted onto an axle by turning lug nuts, not shown, through wheel lug holes 38, mounting the wheel onto a vehicle brake drum, not shown. - The above set out assembly of the individual tire inserts 11 and 12 are fitted within the
tire 30 during tire mounting towheel 34. This assembly allows for the installation of theinsert ring 10 at an optimum location within the tire relative to the undersurface of thetire 30tread 62, as illustrated by arrow A inFIG. 7 . Which positioning provides a clearance indicated by arrow B when thetire 30 is properly aired and is under load. With the assembly of thetire insert segments tire insert 10 is selected to have a diameter to its outer surface that is an optimum spacing distance from thetread 62undersurface 61. This is a great improvement over earlier continuous insert ring systems whose diameter was limited by the diameter of the tire bead, where, with the one side of the continuous tire insert fitted into the tire, the tire bead had to be physically pulled across the other side of the continuous tire insert. In practice, thetire insert 10 of the invention can be positioned as close as one to two inches to the tire tread undersurface, minimizing the tire side wall folding should thetire 30 lose pressure, greatly reducing tire heating from side wall flexure as is rolls under load and significantly increasing the distance thetire 30, under load, can safely travel. - In practice, a urethane material formed to have a hardness of approximately seventy to ninety Shur A has been used successfully in forming the
tire insert segments tire insert segments tire insert 10, it should be understood that as few as two tire insert segments, arranged for fitting together into a ring as thetire insert 10, for mounting, as shown and described above, to the wheel rear and front sections, could be so used within the scope of this invention. Accordingly, it should be understood, the invention is in a plurality oftire insert segments tire insert 10 ring, as shown and described. - In practice, the run flat tire insert of the invention has been installed in a heavy duty transport tire where, after its installation, the tire was aired to approximately one hundred five pounds and was mounted on a vehicle to carry a load of approximately seven thousand pounds. In the installation of the tire insert in the tire, the spacing distance between the
tire insert ring 10 and the tire surface under the tread was approximately one to two inches. Which arrangement provided a run flat tire that supported the design load after deflation for a significant travel distance greater than fifty miles at speeds of fifty miles per hour. - While a preferred embodiment of our invention in a run flat tire insert system has been shown and described herein, it should be understood that variations and changes are possible to the invention and method for its assembly into a run flat tire insert, and the materials that are preferably used in its construction, without departing from the subject matter coming within the scope of the following claims, and a reasonable equivalency thereof, which claims we regard as our invention.
