Abstract: A pneumatic tire is provided with a pair of shoulder lands, and each of the shoulder lands has arranged therein shoulder lug grooves and first sipes. The opposite ends of each of the first sipes terminate within a shoulder land, and the outer end of the first sipe in the axial direction of the tire is located on the inside of a ground contact end of the tread in the width direction of the tire. The sum of the lengths of the first sipes provided in the shoulder land located facing the inside of a vehicle when the tire is mounted on the vehicle is greater than the sum of the lengths of the first sipes provided in the shoulder land located facing the outside of the vehicle. The shoulder land located facing the inside of the vehicle is provided with second sipes extending in the circumferential direction of the tire on the inside of the first sipes in the axial direction of the tire.

The axial width W2 of the shoulder land portion is 1.15 to 2.0 times the axial width W1 of the crown land portion. Crown axial grooves disposed in the crown land portions have a groove width of at most 2 mm and are inclined to the opposite direction to the inclining direction of the radially outermost belt ply cords. Shoulder axial grooves disposed in the shoulder land portions are inclined to the same direction as the inclining direction of the radially outermost belt ply cords. Each of the shoulder axial grooves is not connected to the main groove or alternatively connected to the main groove through a narrow part having a width of 1.2 mm or less.

Abstract: A tire is provided having a tread region that includes continuous ribs which extend diagonally across the transverse direction of the tire. Partial sipes are provided at the trailing edges of the ribs. Full sipes can also be provided with the partial sipes. The ribs may form various patterns such as e.g., an S-shaped pattern, chevron pattern, and others. The tire provides improved traction performance over non-diagonal ribs while still providing desirable rolling resistance performance and control of irregular wear.
