Title:
A TIRE COMPRISING A TREAD
Document Type and Number:
WIPO Patent Application WO/2018/079800
Kind Code:
A1
Abstract:
A tire has a tread comprising at least two radially superposed portions which comprise radially external/internal portions. The external portion is made of a first rubber composition which is based on at least an elastomer matrix, a reinforcing filler comprising between 80 and 200 phr of a reinforcing inorganic filler, and a plasticizing agent. The internal portion is made of a second rubber composition which is based on an elastomer matrix comprising 20 to 100 phr of a first diene elastomer bearing at amine and SiOR functions, and optionally, 0 to 80 phr of a second diene elastomer which is different from the first diene elastomer, a reinforcing filler comprising 20 to 120 phr of a reinforcing inorganic filler, and a plasticizing agent comprising 5 to 100 phr of a liquid plasticizer having a glass transition temperature of less than -80℃.
