    摘要： It is an object of the present invention to provide a pneumatic tire capable of securing rigidity of a tip end of a block, and effectively preventing deviated wear of a tread surface. In a tread surface of a pneumatic tire formed with a block 30 having a tip end 31 which is tapered as viewed from above, and a block 20 having a sidewall surface 25 opposed to a sidewall surface 32 of the block 30, the tip end 31 of the block 30 is provided with a taper cut portion 33 whose land portion height is gradually reduced toward its tip end side, and a bridge portion 34 which is connected to the sidewall surface 25 of the block 20 at a substantially constant land portion height from the tip end of the taper cut portion 33.

    摘要： A pneumatic tire is provided, where the rigidity of the blocks formed on the tread surface is increased and an increase in the level of noise when the tread surface is worn can be prevented. In a pneumatic tire where a number of blocks which are separated by a number of grooves are formed on tread surface, these grooves comprise main grooves that extend along the direction around the tire, or across the direction around the tire, sub-grooves that extend so as to connect to these main grooves, a pair of first raised bottom portions formed in the vicinity of the two ends of each portion of sub-groove which separates blocks, and at least one second raised bottom portion that is formed between each pair of the first raised bottom portions.

    摘要： A pneumatic tire with rim protectors protruding outwardly from the outer side of a tire a distance greater than the outer surface on at least one outer surface of the sidewalls from the bead portions toward the tread and continuously formed in the tire circumferential direction. The rim protectors have the first top portion protruding outwardly from the tire outer side a distance greater than the outer surface through a first hillside portion in a cross-sectional shape from the bead portions toward the tread and a second top portion protruding in a stepped state from the first top portion through the second hillside portion. The second hillside portion extends more to the tire inner side and connects a vertex of the first top portion and an end point in a tread side of a virtual arc on the outer surface of the sidewalls.

    摘要： A pneumatic tire is provided with a main groove extending along a tire circumferential direction in a tread. A side wall of a land portion facing the main groove extends so as to be inclined with respect to a tire circumferential direction between a pair of corner portions. The corner portion positioned in an inner side in a width direction of the main groove is set to an inner corner portion and the corner portion positioned in an outer side is set to an outer corner portion. In the inner corner portion, the side wall is formed by a stepped surface expanding to the outer side in the width direction toward a groove bottom and an expansion to the outer side in the width direction in the stepped surface is made smaller from the inner corner portion toward the outer corner portion.

    摘要： A pneumatic tire comprises grooves 1 to 3 formed in a tread and land portions 4 each having an acute angle portion 5 formed by the grooves 2 and 3. The acute angle portion 5 is chamfered by a plurality of chamfered surfaces 11 and 12 to form into a step shape by the chamfered surfaces 11 and 12 and a connecting surface 21 that connects the adjacent chamfered surfaces 11 and 12. Furthermore, from one sidewall to the other sidewall of the acute angle portion 5 at an end 6 of the acute angle portion 5, a height H1 of the chamfered surface 11 and a height H2 of the chamfered surface 12 are gradually decreased while a length L1 of the chamfered surface 11 and a length L2 of the chamfered surface 12 are gradually increased.
