ABSTRACT:
The radius of curvature of the end portion of the block of a tire at the equatorial plane side of the tire is the same as the radius of the tire thereat. On the other hand, the radius of curvature of the end portion of the block at the shoulder side is smaller than the radius of the tire thereat, and the point which protrudes furthest is between the center and the trailing edge portion of the block 16. The shape of the radially outward surface of the block protrudes further toward the shoulder side end portion, which is an area in which the wear of the leading edge portion progresses furthest. The ground contact pressure at the shoulder side becomes even lower. Accordingly, the leading edge portion can smoothly slide against the road surface. As a result, the progress of the wear from the leading edge portion is promoted, and the effect of preventing the heel-and-toe wear becomes higher.
