This invention provides a tread for retread tire capable of lowering a running temperature to suppress deterioration of peel strength at a retreading face between a tread and a base tire and further obtaining a good peel strength without sacrificing a tear resistance. In a tread 1 for retread tire comprising a cap rubber 2 located side a front surface of the tread and a base rubber 3 located side a bottom surface of the tread, a loss tangent (tan ´) of the base rubber 3 at 25°C and 2% strain is not more than 0.10 and an elongation at break (Eb) of the base rubber 3 is not less than 460%. Also, this invention provides a retread tire comprising such a tread for retread tire. |
