Abstract
A pneumatic tire in which a sipe, which is substantially parallel to a contour line of a trailing edge of a ground-contact configuration, is formed in a trailing edge region of each block at shoulder sides of the pneumatic tire. From a time of step-in to a time of kick-out of a block, the effect of shearing strain which is transmitted to a trailing edge from a preceding trailing edge portion is mitigated, and movement of the trailing edge of the block with respect to a road surface is suppressed. Accordingly, wear at the trailing edge of the block, i.e., heel-and-toe wear, is suppressed, and noise caused by heel-and-toe wear is reduced.
