Title: PNEUMATIC TIRE
Abstract:
The purpose of the present invention is to improve uneven-wear resistance and to reduce noise while maintaining performance of the pneumatic tire 1 on ice/snow. A lug groove 15 is such that a portion thereof demarcating the front side of a block 20 in a tire rotation direction is inclined toward the rear side in the tire rotation direction as that portion extends outward in a tire width direction from the tire equator line CL side. Among multiple small blocks 40 partitioned in the block 20 by sipes 30, a small block 40 adjoining the lug groove 15 which demarcates the front side of the block 20 in the tire rotation direction, and a circumferential main groove 10 which demarcates the tire equator line CL side is a leading-edge-side block 41, and a small block 40 having a portion located on the rearmost side of the block 20 in the tire rotation direction is a trailing-edge-side block 42. Among the small blocks 40, the trailing-edge-side block 42 has a larger area than the leading-edge-side block 41, and intermediate blocks 43 are larger than the trailing-edge-side block 42.
