    摘要: A pneumatic tire has a tread that is provided with a plurality of blocks comparted in a tire circumferential direction by a lateral groove. A sipe formed in each of the blocks has a narrow portion that is open in a tread surface, and a wide portion that is communicated with an inner side in a tire diametrical direction of the narrow portion and is widened than the narrow portion. The wide portion gradually increases a widening length in one side in a width direction and gradually decreases a widening length in other side in the width direction, from one end portion of the sipe toward other end portion, and accompanies an angle change at a time of appearing on the tread surface due to a progress of a wear.

    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.

    摘要: A pneumatic tire has a tread pattern including a plurality of main grooves extending along a tire circumferential direction, and a shoulder land portion constructed by a rib or a block row formed in an outer side in a tire width direction of the main groove positioned in an outermost side. A circumferential sipe is provided in each of the shoulder land portions in both sides in the tire width direction. The number of the circumferential sipes provided in the shoulder land portion in a vehicle inner side is larger than the number of the circumferential sipes provided in the shoulder land portion in a vehicle outer side.
