RUBBER COMPOSITION FOR TIRE |
| 摘要 |
An object of the present invention is to provide a rubber composition for tire that is excellent in abrasion resistance, initial grip performance and stability of grip performance while maintaining processability. The rubber composition for tire comprises a diene rubber component, a hydrocarbon resin containing a component unit derived from a monomer component having a heteroatom or a hydrogenated product thereof (resin A) and a hydrocarbon resin that does not contain a component unit derived from a monomer component having a heteroatom or a hydrogenated product thereof (resin B), wherein a content ratio (mass ratio) of the resin B to the resin A is 0.1 to 50. |
