ABSTRACT:
Pneumatic tires having an improved steering response have a tread portion which comprises a blend of a base elastomer and, as a steering response substance, a polymer of an unsaturated compound selected from methacrylic acid, acrylic acid and lower alkyl esters thereof. The steering response substance is preferably a graft copolymer of polyisoprene and methylmethacrylate. A preferred amount of the steering response substance is in the range from 5 to 60% by weight of the total of the base elastomer and the steering response substance.
