The invention relates to a tire with a component composed of a rubber composition containing at least two diverse carbon blacks. In one aspect such tire is a heavy tire and such component is a tread for a heavy tire which contains at least two diverse carbon blacks to aid in providing an improved path for thermal conductivity for a heavy tire with its relatively thick cross section such as, for example, its relatively thick tread.

Tire with tread of rubber composition containing diverse carbon blacks

A barrier layer composition for a pneumatic tire that contains a mixture of an 4-phenyl isocyanate and sulfur as a crosslinking material, with higher than normal levels of filler or reinforcing material loading. The barrier layer formulation exhibited improved green strength properties, and also improved aged flex life, aged tear, and reversion resistance.

Barrier layer composition

A method is disclosed for increasing the rate of vulcanization of a halogenated isobutylene sulfur rubber composition comprising heating said halogenated isobutylene rubber composition to a temperature ranging from 100&deg; C. to 200&deg; C., wherein said halogenated isobutylene rubber composition contains from 0.05 to 10 phr of sodium thiosulfate pentahydrate.

This invention relates to the discovery that the combination of a hydrated thiosulfate and a bismaleimide compound provides for excellent final rubber vulcanizate physical properties including improved adhesion to aramid reinforcement.

Rubber compound containing a hydrated thiosulfate and a bismaleimide

Pneumatic rubber tire containing reinforcing steel elements therein characterized in that said tire has an adherent inner liner or an inner tube with its polymer portion comprised of a halobutyl rubber and/or copolymers of isobutylene and cyclopentadiene mixed with a prescribed polybutene polymer.
