Radial carcass tire of large width employing two axially-spaced carcass expansion limiting blocks

摘要

A tire having a ratio H/B at most equal to 0.75, H being the radial height of the tire on its rim and B the maximum axial width of the tire, is improved due to the fact that between the radial carcass reinforcement and the tread reinforcement there are arranged two limiting blocks which are located on opposite sides of the equatorial plane. Each limiting block is formed of two superimposed crossed plies of wires or cables of low extensibility which form with the longitudinal direction angles of opposite sign, each being both other than zero and less than one-half of the smallest angle used in the tread reinforcement.
