Abstract
A tread for a pneumatic tire includes central tread elements and shoulder tread elements having leading and trailing tread edges. A pair of circumferentially continuous grooves, one on each half ol the tread, and a plurality of lateral grooves extending from each tread edge toward the center of the tread are provided. The lateral grooves adjacent the central tread elements are curved in shape extending along a line, the line extends toward the center of the tread to form an apex from the center extending outwardly across the tread pattern changing in an opposite direction at an intersection of the circumferential groove along a second line adjacent the shoulder tread element. Shoulder tread elements are arranged in two rows, one row adjacent each lateral edge, the leading edges of the shoulder tread elements being inclined relative to the direction of rotation of the tire.
