Abstract: A tire-chain assembly for a vehicle-mounted wheel basically comprises annular inner and outer holders respectively engaging the inner and outer faces of the wheel. At least one traction chain crisscrosses over the road-engaging surface of the wheel between the two holders. The inner holder is of variable diameter, so that it can be fitted over the tire and then have its diameter decreased to allow the traction chain to be tightened on the wheel. Mechanism on this inner holder is connected via a flexible element that passes over the road-engaging surface of the wheel to the outer face of the wheel so that a pull on this mechanism will reduce the diameter of the inner holder and tighten the chain assembly on the wheel. The outer end of this flexible element, which may be a chain, is then secured to the holder on the outer surface of the wheel.

At least one layer of nylon or similar textile cords which shrink when the tire is heat cured is disposed between the radially outermost layer of metallic cords and the tread. The textile cords are disposed around the circumference of the tire in planes which are substantially parallel to the longitudinal direction of the tire and at densitities along the lateral edges of the breaker which are at least about 50% higher than the density thereof in the crown zone of the breaker.

Abstract: A pneumatic radial tire has as a reinforcement for a crown a belt consisting of a plurality of laminated plies whose cords intersect to each other. A coating rubber having a higher modulus is applied to the central zone of the belt which would be subjected to the most of the vertical stresses caused by the inner air pressure when the tire is inflated, and a coating rubber having a lower modulus is applied to the edge zones of the belt. The lower modulus coating rubber has a high elongation and a high tensile strength at break which serve to reduce shearing strains at the edges of the belt. Such coating rubbers having different properties are used in central and edge zones of the belt to match the requirement of the strengths of the belt, thereby increasing the service life of the tire.
