BRIEF DESCRIPTION OF THE DRAWINGS
[0010] These and other features will become more apparent from the following description in which reference is made to the appended drawings, the drawings are for the purpose of illustration only and are not intended to be in any way limiting, wherein:
FIG. 1 is a side elevation view of a tire with a supplemental tire tread attached.
MG. 2 is a front perspective view in section of a tire with a supplemental tire tread attached.

DETAILED DESCRIPTION
[0011] A supplemental tire tread, generally identified by reference number 10, will now be described with reference to FIG. 1 through 4.
[0012] Supplemental tire tread 10 is intended for use on a wheel 100 that includes a solid tire 102 mounted on a rim 104. Solid tire 102 has an outer tire surface 106, an inner tire surface 108 that engages rim 104, and sidewalls 110 that extend between inner tire surface 108 and outer tire surface 106. Rim 104 may be any typically rim commonly used for tires, such as those made from metal, and is the structural element that attaches wheel 100 to the drivetrain of the vehicle or equipment on which it is installed (not shown), and supports the tire 102.
[0013] As can be seen for example in FIG. 2, supplemental tire tread 10 is intended for use on a solid tire, including those that may be found on various types of industrial equipment, such as trucks, telehandlers, etc. As used herein, the term "solid tire" is intended to cover any tire that structurally or mechanically supports the outer tire surface away from the rim by a material, rather than pneumatic pressure. For example, solid tire 102 may be made entirely from rubber, such as may be made in a single mold, or by layering different layers of rubber, which allows different types of rubber to be used. Solid tire 102 may also be a composite structure, such as one that includes metal bands embedded within rubber or polymeric materials, and/or multiple types of rubber or polymeric materials.
Alternatively, solid tire 102 may have a cavity that is filled with a structural foam or a polymer. Solid tire 102 may be manufactured as a solid tire, or may be converted from a pneumatic tire by filling the pneumatic tire with a structural material such as a foam or other filler, such that pneumatic pressure is not relied upon to support the tire. The various types of solid tires and methods of making solid tires are known in the art, and will not be described further.
[0014] Referring to FIG. 1 and 2, supplemental tire tread 10 is installed on wheel 100.
Supplemental tire tread 10 has a tread body 12 with an outer tread surface 14, and an inner surface 16 that faces outer surface 106 of tire 102. Tread body 12 is preferably strong and flexible, and may be made from, for example, a material similar to what is used for conveyor belts. Other suitable materials will be recognized by those skilled in the art. Outer tread 14 surface preferably includes a ground-engaging profile, such as treads 18 that are mounted to tread body 12 that have a sufficient thickness to provide supplemental tire tread 10 with the desired traction in the anticipated conditions of use. The size, shape, orientation, and location of treads 18 will be based on the preferences of the user and the anticipated ground conditions. In the example depicted in FIG. 6, the treads include main treads 18a, and intermediate treads 18b that are smaller than, and spaced between, main treads 18a.
[0015] Referring to FIG. 1 and 2, inner surface 16 is designed to engage outer surface 106 of tire 102. As shown, tire supports 20 are mounted to inner surface 16 of tread body 12 that engage tires 102. The number of tire supports 20 and their shape may vary depending on the preferences of the user. As shown in FIG. 1, additional tire engaging elements 22 are also included on inner surface 16 of tread body 12 between tire supports 20 to increase the engagement area between tire 102 and tread body 12.
[0016] Tread body 12 may be connected on the tire by any suitable connection. In the depicted example, tread body 12 is preferably designed as a single length of material that is wrapped around and connected end-to-end around the tire using a connection 24.
Preferably, the connection is made to keep tread body 12 as tight as possible, however the anchors 26, which will be discussed below, are primarily responsible for preventing relative rotation of the tire and the tread body.
[0017] In one example, referring to FIG. 2 and 3, tire supports 20 may be described as saddles that have a transverse support 21 that extends transversely across outer surface 106 of tire 102, and opposed sidewall supports 23 that extend away from inner surface 16 of tread body 12 to define tire receiving receptacle 30 and engage opposite sidewalls 110 of solid tire 102. As depicted, transverse supports 21 extend out past the sides of tire 102 such that they are able to support a tread body 12 that is wider than the tire 102 itself.
The actual width of transverse supports 21 and tread body 12 will depend on the preferences of the user and the conditions in which it is intended to be used. Side gussets 25 may also be included as shown to provide additional structural support.
[0018] In another example, referring to FIG. 2 and 3, tire supports 20 are also provided with anchor receptacles 32. Referring to FIG. 2, tire receiving receptacles 30 receive outer surface 106 of solid tire 102 such that tire receiving receptacles 30 support tread body 12 against relative transverse movement of solid tire 102 and tread body 12.
Anchor receptacles 32 as shown are apertures that receive anchors 26 that engage solid tire 102.
Anchors 26 pierce tire body 102 such that anchors 26 support tread body 12 against relative rotation of wheel 100 and tread body 12. As shown, anchors 26 pierce sidewalls 110, and are pin connectors such as threaded anchors that are threaded into engagement with the solid tire, where the thread or flight grips the material of solid tire body 102.
[0019] In another example, referring to FIG. 4 and 5, anchors 26 may also extend through outer surface 106 of tire 102. Installing anchors 26 through sidewalls 110 protects the bolt heads of anchors 26 against unnecessary wear and makes them easier to inspect, clean, and install or remove if needed. However, installing anchors 26 through outer surface 106 is generally easier to install and provides a more stable connection between tread body 12 and solid tire 102. Anchors 26 may be installed through anchor receptacles 32 in tire supports 20, which would then be provided in crosspiece 21, rather than side pieces 23 (not shown). Alternatively, as shown in FIG. 4 and 5, a separate attachment that carries apertures
[00071 According to an aspect, there is provided, in combination, a wheel comprising a solid tire mounted on a rim, the solid tire having an outer surface and an inner tire surface that engages the rim, the outer surface comprising an outer tread surface and sidewalls that extend between the inner tire surface and the tread surface, a supplemental tire tread installed on the wheel, the supplemental tire tread comprising a tread body having an outer tread surface, an inner surface, and an attachment for attaching the tread body around the tread surface of the tire, wherein the inner surface of the tread body comprises tire supports, the tire supports comprising tire receiving receptacles that open away from the inner surface of the tread body and receive the outer surface of the solid tire such that the tire receiving receptacles support the tread body against relative transverse movement of the solid tire and the tread body, and the tread body comprises anchor receptacles and anchors that are engaged between the anchor receptacles and the solid tire, the anchors piercing the outer surface of the solid tire such that the anchors support the tread body against relative rotation of the solid tire and the tread body.
[0008] According to other aspects, the tire supports may comprise saddles having a transverse support that extend transversely across the outer surface of the tire and opposed sidewall supports that extend away from the inner surface of the tread body and engage opposite sidewalls of the solid tire, the anchor receptacles may comprise apertures in the transverse support or the sidewall supports, the apertures receiving pin anchors, the anchor receptacles may comprise apertures that receive pin anchors, the pin anchors may extend at least 3 inches into the solid tire, the anchor receptacles may comprise apertures in the tread body that receive pin anchors, the apertures being positioned such that, when the tread body is installed on the solid tire, the apertures are adjacent to the outer surface of the solid tire and the pin anchors engage the outer surface of the solid tire, and the anchor receptacles may comprise an outer support on the outer tread surface, and an inner support on the inner surface of the tread body that supports the tread body against the outer tread surface of the tire.
[0009] In other aspects, the features described above may be combined together in any reasonable combination as will be recognized by those skilled in the art.
BRIEF DESCRIPTION OF THE DRAWINGS
[0010] These and other features will become more apparent from the following description in which reference is made to the appended drawings, the drawings are for the purpose of illustration only and are not intended to be in any way limiting, wherein:
FIG. 1 is a side elevation view of a tire with a supplemental tire tread attached.
MG. 2 is a front perspective view in section of a tire with a supplemental tire tread attached.

DETAILED DESCRIPTION
[0011] A supplemental tire tread, generally identified by reference number 10, will now be described with reference to FIG. 1 through 4.
[0012] Supplemental tire tread 10 is intended for use on a wheel 100 that includes a solid tire 102 mounted on a rim 104. Solid tire 102 has an outer tire surface 106, an inner tire surface 108 that engages rim 104, and sidewalls 110 that extend between inner tire surface 108 and outer tire surface 106. Rim 104 may be any typically rim commonly used for tires, such as those made from metal, and is the structural element that attaches wheel 100 to the drivetrain of the vehicle or equipment on which it is installed (not shown), and supports the tire 102.
[0013] As can be seen for example in FIG. 2, supplemental tire tread 10 is intended for use on a solid tire, including those that may be found on various types of industrial equipment, such as trucks, telehandlers, etc. As used herein, the term "solid tire" is intended to cover any tire that structurally or mechanically supports the outer tire surface away from the rim by a material, rather than pneumatic pressure. For example, solid tire 102 may be made entirely from rubber, such as may be made in a single mold, or by layering different layers of rubber, which allows different types of rubber to be used. Solid tire 102 may also be a composite structure, such as one that includes metal bands embedded within rubber or polymeric materials, and/or multiple types of rubber or polymeric materials.
Alternatively, solid tire 102 may have a cavity that is filled with a structural foam or a polymer. Solid tire 102 may be manufactured as a solid tire, or may be converted from a pneumatic tire by filling the pneumatic tire with a structural material such as a foam or other filler, such that pneumatic pressure is not relied upon to support the tire. The various types of solid tires and methods of making solid tires are known in the art, and will not be described further.
[0014] Referring to FIG. 1 and 2, supplemental tire tread 10 is installed on wheel 100.
Supplemental tire tread 10 has a tread body 12 with an outer tread surface 14, and an inner surface 16 that faces outer surface 106 of tire 102. Tread body 12 is preferably strong and flexible, and may be made from, for example, a material similar to what is used for conveyor belts. Other suitable materials will be recognized by those skilled in the art. Outer tread 14 surface preferably includes a ground-engaging profile, such as treads 18 that are mounted to tread body 12 that have a sufficient thickness to provide supplemental tire tread 10 with the desired traction in the anticipated conditions of use. The size, shape, orientation, and location of treads 18 will be based on the preferences of the user and the anticipated ground conditions. In the example depicted in FIG. 6, the treads include main treads 18a, and intermediate treads 18b that are smaller than, and spaced between, main treads 18a.
[0015] Referring to FIG. 1 and 2, inner surface 16 is designed to engage outer surface 106 of tire 102. As shown, tire supports 20 are mounted to inner surface 16 of tread body 12 that engage tires 102. The number of tire supports 20 and their shape may vary depending on the preferences of the user. As shown in FIG. 1, additional tire engaging elements 22 are also included on inner surface 16 of tread body 12 between tire supports 20 to increase the engagement area between tire 102 and tread body 12.
[0016] Tread body 12 may be connected on the tire by any suitable connection. In the depicted example, tread body 12 is preferably designed as a single length of material that is wrapped around and connected end-to-end around the tire using a connection 24.
Preferably, the connection is made to keep tread body 12 as tight as possible, however the anchors 26, which will be discussed below, are primarily responsible for preventing relative rotation of the tire and the tread body.
[0017] In one example, referring to FIG. 2 and 3, tire supports 20 may be described as saddles that have a transverse support 21 that extends transversely across outer surface 106 of tire 102, and opposed sidewall supports 23 that extend away from inner surface 16 of tread body 12 to define tire receiving receptacle 30 and engage opposite sidewalls 110 of solid tire 102. As depicted, transverse supports 21 extend out past the sides of tire 102 such that they are able to support a tread body 12 that is wider than the tire 102 itself.
The actual width of transverse supports 21 and tread body 12 will depend on the preferences of the user and the conditions in which it is intended to be used. Side gussets 25 may also be included as shown to provide additional structural support.
[0018] In another example, referring to FIG. 2 and 3, tire supports 20 are also provided with anchor receptacles 32. Referring to FIG. 2, tire receiving receptacles 30 receive outer surface 106 of solid tire 102 such that tire receiving receptacles 30 support tread body 12 against relative transverse movement of solid tire 102 and tread body 12.
Anchor receptacles 32 as shown are apertures that receive anchors 26 that engage solid tire 102.
Anchors 26 pierce tire body 102 such that anchors 26 support tread body 12 against relative rotation of wheel 100 and tread body 12. As shown, anchors 26 pierce sidewalls 110, and are pin connectors such as threaded anchors that are threaded into engagement with the solid tire, where the thread or flight grips the material of solid tire body 102.
[0019] In another example, referring to FIG. 4 and 5, anchors 26 may also extend through outer surface 106 of tire 102. Installing anchors 26 through sidewalls 110 protects the bolt heads of anchors 26 against unnecessary wear and makes them easier to inspect, clean, and install or remove if needed. However, installing anchors 26 through outer surface 106 is generally easier to install and provides a more stable connection between tread body 12 and solid tire 102. Anchors 26 may be installed through anchor receptacles 32 in tire supports 20, which would then be provided in crosspiece 21, rather than side pieces 23 (not shown). Alternatively, as shown in FIG. 4 and 5, a separate attachment that carries apertures
7 may be provided. This attachment, in the depicted example, includes an outer support 34, such as a piece of flat bar with apertures, that is positioned against outer tread surface 14 of tread body 12, and an inner spacer element 36 between inner surface 16 of tread body 12 and outer surface 106 of solid tire 102. Anchor 26 then passes through outer support 34, tread body 12, and spacer element 36 prior to engaging solid tire 102. Suitable materials may be selected for outer support 34 and spacer element 36, such as metal for outer support 34 to provide sufficient support for anchors 26, and UHMW plastic for spacer element 36. The thickness of spacer element 36 is selected to match the thickness of tire supports 20. In this example, as shown in FIG. 6, anchors 26 are installed between treads 18a and 18b, although the spacing of anchors 26 may be selected according to the demands of a particular design.
[0020] Preferably, anchors 26 have an aggressive, or wide thread that provides suitable force. Anchors 26 may also take other forms that allow them to provide sufficient resistance to removal from tire body 102. In one example, pin connectors 26 were used that extended into tire body 102 about 3 inches. Also preferably, anchors 26 may be welded to, or adjacent to, anchor receptacles 32, or otherwise attached thereto to prevent them from unintentionally having anchors 26 being worked out of tire body 102. As shown in FIG. 3, the head of pin connectors 26 have been tack welded 33 to tire supports 20. In the example shown in FIG. 5, anchors 26 may be secured to outer support 34.
[0021] Preferably, tire supports 20 and anchors 26 are not structurally connected to rim 104 of wheel 100. While this may be an option to help strengthen the connection between tire 102 and tread body 12, it is preferable to avoid such a connection, as some equipment does not permit any modification to the rims 104 of the wheels 100. This is shown in FIG. 1 and 2, where tire supports 20 are separate from rims 104. In some cases, tire support 20 may be welded to rim 104, but it will be understood that this is not generally the preferred approach.
[0022] The features described above may be combined together in any reasonable combination as will be recognized by those skilled in the art.
