Abstract
The invention is directed to a radial medium truck tire having a tread component comprising a vulcanizable rubber composition comprising, based on 100 parts by weight of elastomer (phr), from about 5 to about 30 phr of high trans random SBR; from about 70 to about 95 phr of a combination of high cis-1,4-polybutadiene rubber (BR) and cis 1,4-polyisoprene natural rubber (IR) in a IR/BR weight ratio of from about 1 to about 3; from about 20 to about 40 phr of carbon black; and from about 15 to about 35 phr of precipitated silica.
