A method and apparatus for building a tire comprising fitting a patterned cavity of a tread mould with unvulcanized tread composition, shaping the radially inner surface of the tread to a first profile to accommodate a tread reinforcement breaker, consolidating the assembly and shaping its radially inner surface to a second profile, fitting a tire carcass into the second profile, completing the tire assembly, vulcanizing the assembly in the tread mould and removing it from the mould. The method includes various means for fitting the components for consolidating them and for forming the required profiles for subsequent components.
