Abstract
A tire of the radial or crossing ply carcass type with an asymmetric tread reinforcement is improved due to the fact that a correction block is interposed between the assymetric tread reinforcement and the carcass reinforcement. This correction block consists of two plies of wires or cables which form with the longitudinal direction angles of opposite sign, each both other than zero and less than one-third of the smallest angle used in the asymmetric tread reinforcement. The correction block is preferably centered on the equatorial plane of the tire.
