An elastomeric composition includes at least one elastomeric diene polymer, at least one thermoplastic polymer, and at least one polymer comprising functional groups. The at least one thermoplastic polymer comprises a main hydrocarbon chain. Hydrophilic groups are linked to the main hydrocarbon chain. The functional groups are reactive with the hydrophilic groups. The composition may also include at least one reinforcing filler. The at least one reinforcing filler may include carbon black, silica, or both carbon black and silica. The composition may further include a silica coupling agent, a sulfur-based vulcanizing agent, or both a silica coupling agent and a sulfur-based vulcanizing agent. A tire for vehicle wheels including at least one element including an elastomeric material, where the at least one element include the composition, is also disclosed.

Elastomeric composition and tire comprising the composition

A pneumatic tire for vehicle wheels includes a radial carcass, a tread band, sidewalls and beads, and a belt structure. The tread band is provided with grooves on its surface for coming into contact with the ground and situated on a radial outer surface of the carcass. The sidewalls and beads anchor the tire on a wheel rim. The belt structure is disposed between the tread band and the carcass. Additionally, a fiber-reinforced elastomeric intermediate layer is placed between the belt structure and the tread band. Methods for manufacturing the pneumatic tire are also disclosed.
