Abstract
The invention relates to an all-steelload-carrying low profile radial tire. The all-steel load-carrying low profile radial tire comprises a tire body cylinder, a tire tread, and belted layers arranged between the tire body cylinder and the tire tread, wherein the belted layers consist of a first belted layer, a second belted layer, a third belted layer and a fourth belted layer bonded between the tire body cylinder and the tire tread in sequence; and a separator is arranged between the ends of the second belted layer and the third belted layer. The all-steel load-carrying low profile radial belted layer structure is formed by bonding four belted layers; the tire body is not twisted in the vulcanization process and a defect that tire body wires under the belted layers bend is avoided; and meanwhile, the stress suffered by the central belted layers is reduced, so that a problem of roughness on a tire cavity of a finished product is solved.
