The present invention relates to a tyre comprising a rubber composition which improves the compromise between the stiffness in the cured state and the hysteresis of the composition, which composition comprises: - from more than 50 to 100 phr of polyisoprene containing an epoxidized polyisoprene having a molar degree of epoxidation ranging from 5% to less than 50%, - a carbon black, - a crosslinking system, the epoxidized polyisoprene being an epoxidized natural rubber or an epoxidized synthetic polyisoprene having a molar content of cis-1,4 bonds of at least 90% before epoxidation, or a mixture thereof, with the proviso that, if the epoxidized polyisoprene is an epoxidized polyisoprene having a molar degree of epoxidation of from 5% to 25%, the rubber composition contains more than 50 phr of epoxidized polyisoprene, said composition being free of silica.
