摘要： 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.

摘要： A pneumatic tire 10 having a radially outer tread 12, the tread 12 having a plurality of tread elements defined by grooves arranged circumferentially and laterally around the tread 12 between a pair of lateral tread edges TE to define a tread pattern. The tread 12 has a plurality of tread elements extending across the width of the tread between the lateral edges including central tread elements 24, 26, 28 and shoulder tread elements 20, 22 having leading 21, 25 and trailing tread edges 23, 27. The shoulder tread elements 20, 22 are arranged in two rows SH1, SH2, one row adjacent each lateral edge TE. At least one row of shoulder elements has the leading edges inclined relative to the direction of rotation of the tire 10 having an axially outward portion of the leading edge entering and exiting a footprint contact patch 100 prior to the axially inner portion of the leading edge of the shoulder tread elements 20, 22. The leading edges 21 of one row SH1 of shoulder elements 20 can be oriented equal but oppositely directed relative to the leading edges 25 of the other row SH2, preferably the leading edge 21, 25 of the shoulder tread elements 20, 22 are inclined greater than 0 degrees, preferably 10 degrees or greater relative to a plane perpendicular to an equatorial centerplane EP of the tire. The pneumatic tire 10 can have a non-directional tread pattern 12 wherein both rows SH1, SH2 of shoulder tread elements 20,22 are directionally oriented in the same direction, most preferably the tread pattern is directional having equal, but oppositely oriented shoulder tread elements. Preferably the leading edges 21, 25 of each shoulder element 20, 22 are equally oriented and the leading edge of each shoulder element is inclined at an angle of 10 degrees or greater relative to a plane perpendicular to an equatorial centerplane EP of the tire.
