PNEUMATIC TIRE

摘要

The tire tread consists of an inner layer of ordinary foamed rubber composition and a surface layer of high-hardness rubber composition thereon. The rubber composition forming the surface layer, which is later crosslinked after attaching uncrosslinked on the outer side of the tread and has an average molecular weight of more than 2 milllion, and the surface layer occupies 10-30% of the tread from the outer side. The prepared tire shows improved abrasion resistancy, wheel stability and brake performance on icy road.
