Rubber composition for pneumatic tire |
摘要 |
A rubber composition for a tire, in particular for a tread rubber part of a studless tire, comprising: diene rubber component consisting of natural rubber and/or other diene rubber; powder of hydrophilic modified cellulose amounting 0.1-30 mass parts relative to 100 mass parts of the diene rubber component. In preferred embodiments, the hydrophilic modified cellulose has degree of etherification in a range of 0.2-1.0 and its powder has average particle size in a range of 20 μm to 100 μm. |
