ABSTRACT:
A radial ply pneumatic tire (30) has as asymmetric tread portion (41) having circumferential grooves (50, 51, 52, 53) and diagonal grooves (55, 56) therein. The tread is divided into three axial regions (A, B, C) of equal width, and in each region the net-to-gross ratio is different. The rate of treadwear in the axially outermost regions (A, B) of the tread are substantially equalized by features including varying groove depths and widths, groove paths, and chamfering the edges of block elements (57, 58, 62, 63) of the tread.
