TIRE FOR VEHICLES HAVING A HIGH WEAR RESISTANCE AND VULCANIZABLE RUBBER COMPOSITION FOR MAKING THE SAME

摘要

A tire (1) for vehicles is described comprising a tread (9) comprising a vulcanized polymeric base including: a) at least one reinforcing filler dispersed in said polymeric base, b) an amount of extractable residue of at least one vulcanization accelerator containing at least one carbon atom bound to at least two sulfur atoms of from 0.5 to 1.8 % by weight based on the total weight of the tread (9); c) an amount of at least one activator, expressed as equivalents of zinc oxide, not higher than 2 % by weight based on the total weight of the tread (9); d) an amount of combined sulfur lower than 2.5 % by weight based on the total weight of the tread (9). Advantageously, said tire has an improved wear resistance, as well as a wet skid resistance and possibly a rolling resistance comparable to those of the known tires for the same type use.
