Zusammenfassung:A pneumatic tire and a process to retread a tire is provided. The retreaded tire has a carcass and a crown region, wherein the crown region comprises a belt reinforcement structure located between the carcass and a tread. The retreaded tire further comprises a cementless cushion layer located radially outward of said belt reinforcement structure, and one or more reinforcement plies located radially outward of the cementless cushion layer. The one or more reinforcement plies is formed from a substantially continuous strip 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. Se proporciona una llanta neumática y un proceso para recauchar la llanta. La llanta recaucha tiene una carcasa y una región de corona, en donde la región de corona comprende una estructura de refuerzo de banda colocada entre la carcasa y una banda de rodamiento. La llanta recauchada comprende además una capa de cojín sin cemento radialmente hacia fuera de la capa de cojín sin cemento. La una o más capas de refuerzo se forma desde una tira substancialmente continua de elastómero reforzada que se enrolla desde un lado de la corona al otro lado de una manera substancialmente continua. La capa de refuerzo se puede formar enrollando espiralmente la tira alrededor de la carcasa, o una o más capas de refuerzo se puede formar desde el arrollamiento de la tira alrededor de la carcasa en un patrón de zigzag.
