    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.

    摘要： In a tire, a phase difference L1 of transverse grooves 2 is within 25% of the length L of blocks 3, the projected portions 11 are alternately on both sidewalls 10, L2 of the portion 11 is 20% to 45% of L, and in the cross-section of the width direction of the main groove 1, the edge 15 of the portion 11 at the groove bottom is more of a sidewall 10 side than a center line 19 of the groove 1, the outline of the portion 11 is at least on a virtual surface 17 that connects the edge 13 of the groove 1 at the tread surface and the edge 15. The tire also has one or a plurality of sub-projected portions 21, 22 projected from the surface 17.

    摘要： An object of the present invention is to provide a pneumatic tire capable of ensuring both of the ice braking performance and the ice turning performance while increasing the dry steering stability performance. To achieve the above object, a sipe extending in a width direction of the tire is formed a land portion, the sipe having: pluralities of wide portions each having an inclined plane that begins from the tread surface of a road surface, and terminates in the half way of a sipe wall while inclining so that a sipe width decreases toward the groove bottom of the sipe, and a pair of side faces connecting the inclined plane and the sipe wall therebetween, wherein the pluralities of wide portions are located alternately on both sipe walls along a longitudinal direction of the sipe.
