TYRE TREAD, THE CROSSLINKING SYSTEM OF WHICH IS BASED ON ORGANIC PEROXIDE
A tire tread comprises a rubber composition based on at least from 10 to 90 phr of a first diene elastomer, the first diene elastomer being a polybutadiene-based elastomer, modified with a functional group capable of interacting with silica as reinforcing filler, the first diene elastomer exhibiting...

Summary: | A tire tread comprises a rubber composition based on at least from 10 to 90 phr of a first diene elastomer, the first diene elastomer being a polybutadiene-based elastomer, modified with a functional group capable of interacting with silica as reinforcing filler, the first diene elastomer exhibiting a glass transition temperature of less than −80° C.; from 10 to 90 phr of a second diene elastomer, the second diene elastomer being a styrene/butadiene copolymer exhibiting a glass transition temperature of greater than −80° C.; from 90 to 150 phr of silica as reinforcing filler; a coupling agent; a plasticizing system comprising a plasticizing resin exhibiting a glass transition temperature of greater than 20° C.; and a crosslinking system based on organic peroxide; the total content of the first diene elastomer and of the second diene elastomer in the composition being within a range extending from 80 to 100 phr. |
