    摘要： A tire (10) and a method to retread a tire is provided. The retreaded tire (10) has a carcass (30) and a crown region, wherein the crown region comprises a belt reinforcement structure (40) located between the carcass (30) and a tread (25). The retreaded tire further comprises a cementless cushion layer (50) located radially outward of said belt reinforcement structure, and one or more reinforcement plies (60) located radially outward of the cementless cushion layer (50). The one or more reinforcement plies is formed from a substantially continuous strip (70) of reinforced elastomer which is wound from one side of the crown to the other side in a substantially continuous manner. The reinforcement ply may be formed from spirally winding the strip about the carcass, or one or more reinforcement plies may be formed from winding the strip about the carcass in a zigzag pattern.
