PURPOSE: A top reinforcement for tire is provided to achieve a substantially improved performance of heavy equipment vehicles having such a tire. CONSTITUTION: A top reinforcement for tire designed for carrying heavy loads, comprises a body reinforcement formed by at least a ply of radial cords(1) and a top reinforcement formed by at least a ply(3) of almost cylindrical reinforcing circumferential elements consisting of main metal and inextensible elements(30), having minimal transverse and radial dimensions at least equal to 0.09 times the square root of the circumferential radius RS of the ply, the filling coefficient of which is at least equal to 0.70, and which is topped with a rubber pad(4) with high modulus of elongation, with crescent-shaped transversal cross section. |
