Radial tyre having a tread with transversal grooves inclined with respect to a normal (N) to the tread surface.

摘要

The tread design of a radial pneumatic tyre for ground vehicles is characterized by transverse grooves (2) on the shoulder ribs (A.E) having an incline from the normal (N) to the contact surface in one direction and the transverse grooves (6) in the center (C) of the tread width being inclined in the reverse direction. Improved wear rates with uniform wear is obtained on a drive axle with proper tyre rotation. A reversed direction of rotation on the non-drive axle results in more even wear with potentiality less vibration and noise.
