ABSTRACT:
In order to reduce the heating at the edges of the tread reinforcement plies, the additional working ply has an axial width which is between 1.05 times the axial width of the tread and 1.1 times the maximum axial width of the radial carcass reinforcement. The cables of this additional working ply follow a geodesic trace and form an angle of between 25.degree. and 65.degree. with the equatorial plane of the tire.
