摘要： A rubber composition for tire treads is disclosed which is designed to exhibit high resistance to skidding on wet, icy and snowy roads. A selected rubber blend of styrene-butadiene rubber and natural rubber and/or polyisoprene rubber is combined with a selected carbon black of specified specific surface areas and also with a selected softener of specified viscosity-gravity constants. The styrene-butadiene rubber consists essentially of two styrene-butadiene block copolymers each having varied styrene and vinyl contents and a specified transition temperature width, one block having a higher glass transition temperature than the other.

摘要： A pneumatic tire of a low profile is disclosed which is constructed with a a cap tread, a sidewall and a tie rubber interposed therebetween. The cap tread is formed from a rubber composition comprised of a styrene-butadiene rubber of a high styrene content. The tie rubber comprises a specified sum of a syndiotatic-1,2-butadiene rubber and a cis-1,4-butadiene rubber. Use of the tie rubber is conductive to sufficient adhesion of the tread to the sidewall without shoulder blistering after vulcanization.
