A pneumatic tire has a sidewall rubber insert axially inward of at least one carcass ply. Such insert may, for example, be an apex extending radially outward from the bead core region of the tire into the sidewall. Alternatively, it may be positioned higher in the sidewall portion of the tire and away from the bead core. Such insert is a rubber composition containg a dispersion of an ultra high molecular weight polyethylene and a dispersion of a starch composite.

Tire with sidewall rubber insert

Pneumatic tire having a rubber component containing a liquid polysulfide compound

The invention relates to the preparation of a partially vulcanized, pre-shaped rubber composition and use thereof as a component of an article of manufacture. In practice, the partially vulcanized rubber composition is adhered to an unvulcanized rubber substrate to form a composite thereof and the resulting composite vulcanized to create an article of manufacture. Such pre-vulcanized rubber composition is a composite comprised of at least one diene-based elastomer, amorphous silica, coupling agent and liquid diene-based polymer. Such partially vulcanized, pre-shaped rubber composition may be a component of a tire such as, for example, an apex, sidewall insert or tread. It may also be a component of an industrial rubber product such as, for example, a component of a conveyor belt, power transmission belt or a hose.
