    Abstract: 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.

    Abstract: 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.

    Abstract: 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.
