ABSTRACT:
A tire tread comprising a rubber composition based on (phr: parts by weight per hundred parts of elastomer):(i) a diene elastomer;(ii) more than 50 phr of an inorganic filler as reinforcing filler;(iii) between 2 and 15 phr of an (inorganic filler/diene elastomer) coupling agent;(iv) between 1 and 10 phr of a methylene acceptor, and(v) between 0.5 and 5 phr of a methylene donor.This tread has, after mechanical running-in of the tire for which it is intended (“auto-accommodation”), a rigidity gradient which increases radially from the surface towards the inside of the tread. Use of such a tread for the manufacturing or recapping of tires. Tires comprising a tread according to the invention, in particular of the snow or ice type (“winter” tires).
