Tread for pneumatic tire carrying heavy loads |
摘要 |
Tyre tread made from a rubber composition has groove(s) each delimited by walls having protruding and/or recessed elements that co-operate with the elements of the opposite wall. The groove width, that is the distance between the walls, varies when the tie is in use and at the limit all the elements of the walls co-operate. The variation in groove width may be the same at any depth in the groove. The groove is widest around the midpoint of its length |
