Abstract:

A pneumatic tire having a carcass and a crown region is disclosed, the crown region comprising a crown reinforcement structure and a tread portion with a radially inner side and a tread on its radially outer side. The crown reinforcement structure is located between the tread portion and the carcass and comprises a plurality of adjacent cord reinforced strips. The cord reinforced strips are in direct contact either with the inner side of the tread portion or are separated from the tread portion only by a rubber cushion layer. A process to manufacture such a tire comprises the steps of: () preparing an assembly with a carcass, a green tread reinforcing rubberized ply layer applied radially upside of the carcass, and a green tread portion applied onto the green tread reinforcing rubberized ply layer, and () transferring the assembly into the pneumatic tire by curing. The green ply layer is formed by winding a continuous green rubberized cord comprising strip radially upside onto the carcass or an intermediate layer applied onto the carcass. The green tread portion is applied in such a way onto the green tread reinforcing rubberized ply layer that it is either in direct contact with the green tread reinforcing rubberized ply layer or that it is separated from the green tread reinforcing rubberized ply layer only by a rubber cushion layer. Slightly modified, this process can also be used to retread a pneumatic tire, in particular an aircraft tire.

Abstract:

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.
