Rubber composition and tire |
abstract |
The present invention provides rubber compositions and tires which provide improved overall performance in terms of wet grip performance and dry grip performance. Included is a rubber composition having a hardness that reversibly changes with water, satisfying the relationships (1) and (2) below, and having a stress at break of 8.0 MPa or more,Hardnesswhendry−Hardnesswhenwater-wet≥1wherein each hardness represents the JIS-A hardness at 25°C of the rubber composition,0.90≤Volumewhenwater-wet/Volumewhendry≤1.01wherein each volume represents the volume at 25°C of the rubber composition. |
