Abstract:
A tire tread and a tire comprising a tire tread, the tire tread having a rubber composition based on a diene elastomer; more than 50 phr of an inorganic filler as reinforcing filler; between 2 and 15 phr of an inorganic filler/diene elastomer coupling agent; between 1 and 10 phr of a methylene acceptor, and between 0.5 and 5 phr of a methylene donor. The tread may be characterized as having a radially increasing rigidity gradient from the surface towards the inside of the tread after mechanical run-in of the tread. In particular embodiments, the tread may be characterized as having a nominal secant modulus at 10% elongation is between 3 and 7 MPa at a radially outer surface of the tread and between 9 and 13 MPa at the most radially inside of the tread.
