Abstract:
1. A tire having at least one component of a rubber composition comprised of at least one conjugated diene-based elastomer, to the exclusion of butyl type polymers, based upon parts by weight per 100 parts by weight rubber (phr): (A) 100 parts by weight (phr) of at least one conjugated diene-based elastomer comprised of: (B) about 1 to about 30 phr of a liquid polyalkylene copolymer selected from: (C) about 25 to about 100 phr of reinforcing filler as: (D) optionally a coupling agent having a moiety reactive with hydroxyl groups of said ethylene/butylene copolymer and hydroxyl groups contained on the surface of said precipitated silica, if said precipitated silica aggregates are used, and another moiety interactive with said conjugated diene-based elastomer(s); wherein said butyl-type rubbers are: (E) copolymers of isobutylene and conjugated diene, (B) halogenated copolymers of isobutylene and conjugated diene, and (C) brominated copolymers of isobutylene and para methylstyrene.
