ABSTRACT:
A pneumatic tire having a tread pattern in which one or more approximately straight longitudinal grooves extending to the circumferential direction of the tire are provided in the tread at a distance (h) from the tire equator to the center of said groove within the range of not more than 2/3 time the distance (H) between the tire equator and the tread edge, said longitudinal groove being composed of repeatedly formed portions each of which has a shape such that the groove width in the tire axial direction between the opposed groove walls varies along the circumferential direction of the tire, whereby the longitudinal grooves, especially those positioned at the center portion of the tread, are prevented from biting small stones without decreasing the wet grip performance of the tire.
