The invention relates to a tire with a rubber tread of a cap/base construction wherein the tread cap is designed to be ground-contacting, wherein the tread base underlies said tread cap, is not intended to be ground-contacting, and is a matrix composition composed of at least one elastomer where the matrix composition contains a dispersed micro inclusion made of a particulate, high molecular weight thermoplastic polymer and wherein the tread cap is composed of a blend of elastomers without such micro inclusion.

Method of preparing tire with tread of cap/base construction

The invention relates to a tire with a tread which is reinforced with a quantitative amount of silica, including a silica coupler, where the tread rubbers are of a blend comprised of styrene/isoprene/butadiene terpolymer rubber and cis 1,4-polybutadiene rubber or styrene/isoprene/butadiene terpolymer rubber, cis 1,4-polybutadiene rubber and isoprene/butadiene copolymer rubber. Optionally, the rubber blend can contain a minor amount of cis 1,4-polyisoprene natural rubber.

Tire with silica reinforced tread

The invention relates to a tire with a tread which is reinforced with carbon black and precipitated silica where the tread rubbers are of a blend comprised of at least one diene-based elastomer and a styrene/alphamethylstyrene resin, as hereinafter described.
