ABSTRACT:
A pneumatic tire having an outer surface of a tread portion divided into a tread pattern by grooves, in which each of the grooves has an intersect portion and an angle of an island portion surrounded by said intersect portion is different from that of another part at the same island portion. In such a tire, running performances on dry road are improved by making a distance in radial direction from an outer surface of the tread portion to a bottom of the groove at the intersect portion larger as the angle becomes smaller.
