RADIAL TIRE

摘要

A radial tire is disclosed for providing improved traction and drainage. The tire has rib grooves (20) at the center of the tread; the lug grooves (20) on both sides; a wide rib (21) with bigger width (w2) and depth (d2) than the rib that is adjacent to the lug and has width (w1) and depth (d1); a wide lug (11) connecting the wide rib (21) and having larger width (w4) and depth (d4) than the adjacent lug with width (w3) and height (h3). The number of the wide rib (21) and wide lug (11) is between 6 and 25 in the same interval along the circumference of the tire; the gap between the wide ribs (21) and wide lugs (11) is irregular; the width (w2) of the wide rib (21) is 1.2 to 1.8 times of the width (w1) of the rib groove; the depth 1.1 to 1.5 times; the width (w4) of the wide lug (11) is 1.2 to 1.8 times of the width (w3) of the lug groove; and the depth 1.1 to 1.5 times.
