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.

A composite of a flexible, releasable backing having discrete portions of thin, sulfur vulcanizable, carbon black filled adhesive rubber composition thereon is used for adhering a tire tread splice and other applications in assembled rubber articles. The adhesive composition comprises a rubber composition containing a sulfur curative together with carbon black, processing oil, and tackifier resin. The invention is further directed to a method of preparing a tire having tread ends joined together with said discrete adhesive composition. The adhesive is applied to the tread from its releasable backing so that tacky adhesive need not be physically contacted by an operator or machine.

The marking of a surface of an uncured diene rubber product with a marking, or identifying coating, which maintains its identity upon curing the rubber. In one aspect, the coating is applied as a water based dispersion of zinc oxide pigment in a sulfur curable polymeric latex binder. An article can be produced thereby as a cured assembly of rubber components.

Rubber surface identification coating and rubber products prepared

The marking of a surface of an uncured diene rubber product with a marking, or identifying coating, which disappears upon curing the rubber. In one aspect, the coating is applied as a water based dispersion of a white colored metallic salt of a fatty acid having a melting point below 150.degree. C. (e.g. zinc stearate) in a sulfur curable polymeric latex binder. An article can be produced thereby as a cured assembly of rubber components.

The marking of an uncured or partially cured rubber surface with a marking, or identifying coating, which basically, disappears upon curing the rubber. In one aspect, the coating is applied as a suspension or solution in a specified solvent mixture. An article can be produced thereby as a cured assembly of rubber components.
