間領域においては低い。In general, the tread portion of heavy-duty pneumatic radial tires used for trucks, buses, etc. has a ri-diameter tread, and the outer widthwise part and the widthwise center part thereof are respectively The sidewalls and belts have high rigidity due to the internal pressure. Therefore, when the regular internal pressure is filled and the regular cylinder is acting, the ground contact pressure of the tread part of the tire is It is high in the area, and low in the pair of intermediate areas between the @ alignment side area and the central area.

度は他の部分より速い。It looks like t. Therefore, when such a heavy-duty pneumatic tire is running, drag occurs in the intermediate region where the ground contact pressure is low, and this region is partially worn, and the wear progresses faster than in other parts.
このため、トレッド部に複数本の主溝を有するリブタイ
での場合には、中間領域に位こするリプにリバーウェア
、リブパンチイング等の偏歴耗が発生するという問題点
がある。For this reason, in the case of a rib tie having a plurality of main grooves in the tread portion, there is a problem in that uneven wear such as river wear and rib punching occurs in the ribs located in the intermediate region.

けることにより解決することができる。Such a problem arises when the tread portion of a heavy-duty pneumatic radial tire is formed with a plurality of side grooves extending in the circumferential direction. A pair of outer regions located at the center in the width direction, a central region located at the center in the width direction, and a pair of intermediate regions located between the outer region and the center region, and divided into five in the width direction, and at least one of the This can be solved by providing a protrusion in the intermediate region that protrudes radially outward and extends circumferentially.

を防出することができる。Since the protrusion that protrudes outward in the radial direction and extends in the circumferential direction is provided in the intermediate region, the wall thickness of the area where the protrusion is provided becomes thicker and the rigidity increases. The stiffness is approximately equal to the stiffness of the region and the center region, and the stiffness is averaged over the entire surface of the tread. As a result, the ground contact pressure of the tread portion becomes uniform throughout, resulting in uneven llj! It is possible to prevent the occurrence of wear and tear.

に示すように、突出部13を設ける以前の値(仮想線で
示す)から実線で示すような値に改善され平均化する。In FIGS. 1 and 2, 1 is a pneumatic tire for freight cargo used for trucks, buses, etc., and this tire 1 extends from one bead to the other bead (not shown) at least 1r! It has a carcass layer 3 of I. In this carcass layer 3, a large number of substantially straight cords are embedded in the equatorial plane 2 of the tire 1. In addition, carcass layer 3
At least two annular belt layers 4 are disposed on the outside in the radial direction, and these belt layers 4 include a large number of belt layers that intersect at a predetermined angle with respect to the equatorial plane 2 and intersect with each other between adjacent layers. A metal cord is buried at 1'. The tire 1 has a tread portion 5 having a radius of curvature (tread radius) of 100 mm, and the tread portion 5 has a plurality of (four in this embodiment) main grooves 6 extending in the circumferential direction and bent in a zigzag manner. are formed, and on both sides of these main grooves 6, land portion rows 7 extending in the circumferential direction are formed.
It is defined by grooves 6. When such a tire l is filled with a regular internal pressure and is run with a regular load applied to it, the ground contact pressure of the pair of outer regions 10 and the center region 11 becomes higher than the ground contact pressure of the pair of intermediate regions 12. It is known empirically from the shape of prints, etc. Here, the outer region 10 refers to a pair of regions located on the outer side in the width direction of the tread section 5, which is divided into five equal parts in the width direction from one tread end 14 to the other tread end 15, Further, the central region 11 is a region located at the center in the width direction, and the intermediate region 12 is a pair of regions located between the outer region IO and the central region 11. In this way, the ground pressure in the outer 11111f1'I region 10 is higher than the ground pressure in the intermediate region 12, and the reason why the ground pressure in the central region 11 is higher than that in the intermediate region 12 is because
This is probably because the central region 11 has high rigidity under the influence of the internal pressure and the belt layer 4. Here, the tire 1
Depending on the type, the ground pressure of the entire intermediate region 12 may be low, or the ground pressure of a part of the intermediate region 12 may be low. Therefore, in the present invention, a protrusion 13 that protrudes radially outward and extends in the circumferential direction is located in a portion of the land section row 7 in the intermediate region 12 where the ground pressure is low (a part or the whole of the intermediate region 12).
will be established. As a result, the wall thickness of the tread portion 5 increases in the portion where the protruding portion 13 is provided, and the rigidity improves, thereby increasing the ground pressure in this portion, and the ground pressure in the intermediate region 12 is lower than that in the outer region 1. , approximately equal to the ground pressure in the central region 11. As a result, dragging in the intermediate region 12 is prevented.
As a result, the rate of menopause becomes uniform throughout the tread portion 5, and uneven menopause caused by river wear, rib punch, etc. can be prevented. In addition,
Depending on the type of tire, the low ground pressure area may extend to part of the outer region 10 and central region 11;
In this case, a protrusion connected to the protrusion 13 of the intermediate region 12 may be provided in the region 1O111, and the protrusion a of the protrusion 13 is preferably in the range of 0.1 mm to 2.0 am. This is because if it is less than 0.1 tsm, the rigidity of the part where the protrusion 13 is provided can hardly be improved, and if it exceeds 2.0 am, only the protrusion 13 will touch the road surface. This is because you will end up hitting one side. A land column within the intermediate area 12 as shown in FIG. When the protrusions 13 are provided throughout, the ground pressure is improved and averaged from the value before the protrusions 13 (shown by the imaginary line) to the value shown by the solid line, as shown in FIG.
なお、中間領域12における偏摩耗はサイドフォースに
より進行する場合もあるので、突出部13は中間領域1
2のいずれか一方の領域に設ければよい。Note that uneven wear in the intermediate region 12 may progress due to side force, so the protrusion 13
It may be provided in either one of the two areas.

The tires used were the ribbed tires shown in FIGS. 1 and 2, and the internal structures such as the carcass layer were the same in the conventional tire and the test tire to which the present invention was applied. Further, the protrusion a of the protrusion is 0.3 am. Also, what is the wear of the land rows provided with the protrusions when such conventional tires and test tires are mounted on an actual vehicle and traveled for 50,000 km? compared. the result.
