Pneumatic tire for passenger car including wave-shaped belt reinforcing
elements
Abstract:
A pneumatic tire for a passenger car includes a toroidal carcass anchored by a pair of beads and a belt made of laminated strips. The strips have a number of reinforcing elements of cords or filaments surrounding a crown of the toroidal carcass and are coated with a high molecular weight material having a modulus of elasticity less than that of the reinforcing elements. The belt is of a laminated construction of a first layer and a second layer of a single strip. The first layer has wave-shaped reinforcing elements arranged side by side and directing in parallel with an equatorial plane of the tire, while the second layer has reinforcing elements arranged in parallel with each other at angles of 15.degree.-75.degree., preferably 35.degree.-60.degree. with respect to the equatorial plane.
