Abstract

A method of making tyres having >=3 layers of parallel cords in the tread region, all at different angles to constitute a triangular pattern of reinforcing ply, is as follows: one layer or portion of cords is embedded into the tyre rough while its shape is still cylindrical, then this rough is curved to the final shape, then the other layer(s) of cords is/are introduced, and the tyre is pressed and vulcanised. Pref. the cord layer(s) first introduced is/are overlaid by at least one further layer of carcass material.
