ABSTRACT:
A pneumatic tire in which the uneven wear resistance and durability are improved without sacrificing the on-the-snow performances. The tire comprises a tread portion provided with blocks each having a top surface of which the centroid is located within the ground contacting width, each block provided with circumferentially spaced axially extending sipes. In each block, the depths of the sipes gradually increasing from both the circumferential edges of the block toward the circumferential central portion of the block so that at least one deepest sipe exists in the circumferential central portion, and the maximum depth of the deepest sipe being in the range of from 0.6 to 0.9 times the depth of the circumferential grooves. Preferably, the depth of each sipe is gradually decreased from the axially inside to the outside of the tire.
