<p>A pneumatic tire including a tread provided with a plurality of blocks. Tread surfaces of the blocks 18 are provided with second arcuate portions 20B, which have a center of curvature outside of the tire, at a leading edge 18f side and a trailing edge 18k side of a first arcuate portion 20A, which has a center of curvature inside of the tire. <??>With this configuration, bending deformation of the entire block can be suppressed by delaying a timing of ground contacting at the time of contact, so that the bending deformation in a direction opposite to a rotational direction of the tire, generated in the vicinity of the trailing edge 18k right before leaving, thus suppressing heel-and-toe wear in the block. <IMAGE></p> |
