Abstract

A pneumatic tyre has reinforcing plies in the tread portion, each ply comprising a layer of rubber reinforced with steel cables. The edges of the lower ply are folded upwardly around the edges of the upper plies and on each side of the reinforcing plies is provided a band of rubber having good shock absorption characteristics and extending in the direction of propagation of the tyre. The strength of the tyre is increased in the regions adjacent the edges of the reinforcing plies.
