摘要 |
<p>A rubber composition for a tire having improved grip performance on an ice snow road surface while maintaining abrasion resistance performance, containing 5 to 150 parts by mass of an aromatic vinyl polymer and 5 to 200 parts by mass of silica based on 100 parts by mass of a diene-based rubber component containing not less than 20% by mass of a natural rubber and not less than 5% by mass of polybutadiene. It is preferable that a cis content of the polybutadiene is not less than 93%, and a weight average molecular weight of the aromatic vinyl polymer is 300 to 10000.</p> |
