Pneumatique pour véhicule

摘要

This invention relates to belted pneumatic tires, of the kind that have a low cross-section of ratio equal to or less than 0.8. According to the invention, at least the inner part of the tire tread between the carcass crown and the level of the hollows of the tread pattern is made entirely from a rubbery mixture having a high modulus of elasticity. This modulus may be greater than 60 kg/cm2 at 100 percent elongation and said inner part has a thickness which is inherently sufficient to provide effective hooping and banding of the tire crown without recourse to a conventional breaker belt.
