Abstract
A tire with a rubber containing component compound of, based on 100 parts by weight (phr) of rubber, (A) from 10 to 90 phr of a terpolymer rubber having pendant hydroxyl groups; and (B) from 10 to 90 phr of a rubber containing a nitrite moiety.
Claims20
A rubber composition comprising, based on 100 parts by weight (phr) of rubber,
- (A) from 10 to 90 phr of a terpolymer rubber comprised of repeat units derived from
- (1) 30 to 89 weight percent of a conjugated diene monomer which contains from 4 to 8 carbon atoms;
- (2) 10 to 50 weight percent of a vinyl substituted aromatic monomer;
- and
- (3) 1 to 20 weight percent of at least one co-monomer selected from the group consisting of the following general formulas I, II, and III:
- 6
- wherein R represents a hydrogen atom or an alkyl group containing from 1 to 8 carbon atoms;
- wherein R1 represents a saturated alcohol group containing from 1 to 8 carbon atoms;
- (B) from 10 to 90 phr of a rubber comprised of repeat units derived from
- (1) 30 to 99 weight percent of a conjugated diene monomer which contains from 4 to 8 carbon atoms;
- (2) zero to 50 weight percent of a vinyl substituted aromatic monomer;
- and
- (3) 1 to 20 weight percent of an olefinic unsaturated nitrile selected from the group consisting of acrylonitrile, methacrylonitrile, ethacrylonitrile, crotononitrile and mixtures thereof.
