| abstract |
The invention relates to a tire with a rubber tread which is quantitatively reinforced with silica where the tread rubber is composed of a basic rubber composition of high vinyl polybutadiene rubber, one or more isoprene/butadiene copolymer rubbers and cis 1,4-polyisoprene rubber. Optionally, the said basic elastomer composition can also contain a minor amount of cis 1,4-polybutadiene rubber, 3,4-polyisoprene rubber and/or styrene/isoprene copolymer rubber. |
