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.
