Tire Having Diagonal Ribs With Trailing Edge Siping

摘要

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.

主权项

1. A tire defining longitudinal, radial, and transverse directions, the tire comprising:
a pair of opposing shoulders spaced apart along the transverse direction; a tread region extending between the shoulders, the tread region comprising
a plurality of ribs separated by grooves and extending from one of said shoulders to the other of said shoulders, each of said ribs having a rib length and a rib width, wherein along the rib length each of said ribs forms a non-zero angle α from the longitudinal direction; andwherein each of said ribs comprises a leading edge and a trailing edge, the trailing edge defining a plurality of partial sipes spaced apart along the length of the rib, said partial sipes having a sipe length SL that is less than the rib width, the leading edge devoid of any partial sipes.
