摘要： A pneumatic tire wherein a sipe includes protrusions on a first sipe wall face of mutually opposing sipe wall faces and recesses that mate with the protrusions in a second sipe wall face. Additionally, in a projection figure of the protrusions with the sipe wall faces in an expanded state, a relationship between a placement density X of the protrusions in a region that extends up to half of a sipe depth H from an opening of the sipe and a placement density Y of the protrusions in a region that extends up to half of the sipe depth H from a bottom of the sipe is X>Y.

摘要： A pneumatic tire including a plurality of circumferential main grooves extending in a tire circumferential direction and a plurality of land portions partitioned and formed by these circumferential main grooves in a tread portion. Additionally, each of these land portions has a plurality of sipes, respectively. Moreover, not less than 90% of the sipes disposed in the inner side region are constituted by two-dimensional sipes and not less than 90% of the sipes disposed in the outer side region are constituted by three-dimensional sipes. The left and right shoulder land portions each have a plurality of lug grooves arranged in the tire circumferential direction. A pitch number Nin of the lug grooves in the shoulder land portion on the inner side region side and a pitch number Nout of the lug grooves in the shoulder land portion on the outer side region side have a relationship such that Nin>Nout.

摘要： PROBLEM TO BE SOLVED: To provide a pneumatic tire which can improvement on-ice performance and wet performance without deteriorating steering stability on a dry road surface.SOLUTION: A pneumatic tire includes a tread 1, sidewalls 2 and beads 3. The tread 1 is provided with a plurality of pieces of circumferential grooves 11, 12 extended in the tire circumferential direction and a plurality of pieces of lateral grooves 13, 14 extended in the tire width direction. A plurality of blocks 15 are divided by these circumferential grooves 11, 12 and the lateral grooves 13, 14 and a plurality of pieces of sipes 20 extended in the tire width direction are provided in each block 15. In the pneumatic tire, at least a part of the sipes 20 of the plurality of pieces of the sipes 20 formed in each block 15 is constituted of main parts 21 positioned at the center side in the width direction of the blocks 15 and deep bottom communicating parts 22 communicating with the circumferential grooves 11 adjacent to the blocks 15 and having depths of 50% or larger of depths of the circumferential grooves 11. Projections 31 and recesses 32 which mesh to each other are partially formed on a pair of mating faces 22a, 22b that face each other in the deep bottom communicated parts 22 of the sipes 20.
