Abstract
A vehicle tire has an unidirectional tread pattern, and the tread portion is provided with two circumferential grooves to divide the tread portion into two outer parts and a central part there between, the central part being substantially continuous in the tire circumferential direction and formed symmetrically about the tire equator. The outer parts are provided with mirror-image patterns, each formed by circumferentially repeating pattern units having an average circumferential length, and the mirror-image patterns are circumferentially shifted from each other by a distance S of from 0.15 to 0.25 times the above-mentioned average circumferential length.
