ABSTRACT A tyre comprising sidewall, beads and a tread, whose tread 18 formed of an elastomer composition containing as elastomer a styrene-butadiene or a styrene-isoprene co- polymer having a glass transition temperature above minus 50°C., said composition having a rebound resilience of 55% or more. The glass transition temperature is preferably in the range from minus 40°C to minus 25°C and the rebound resilience is preferably in the range from 60% to 70%. Suitable copolymers are styrene-butadiene copolymers having a styrene content in the range from 20% to 25% and a butadiene content correspondingly in the range from 80% to 75% by weight, a molecular weight in the range 400,000 to 500,000, a glass transition temperature in the range from minus 30°C to minus 40°C, and in which from 60% to 75% by weight of the butadiene has polymerised at the butadiere 1.2 position.
