ABSTRACT:
An end of a block18formed on a tread surface of a tire is chamfered in such a manner that a curvature of a chamfer increases toward the end of the block. Accordingly, a ground contact pressure which usually increases locally at the end of the block18is equalized and handling stability of the tire improves. Particularly, since the curvature changes, the ground contact pressure can be controlled corresponding to an actual distribution of ground contact pressure. As a result, the ground contact pressure can be equalized still further and an improvement in handling stability of the tire is achieved.
