Abstract
Official abstract text for this publication.
Provided is a studless winter tire achieving balanced improvements in abrasion resistance and performance on snow and ice. The studless winter tire includes a cap tread formed from a rubber composition, the rubber composition containing a rubber component including natural rubber and polybutadiene rubber, an aromatic oil, and silica, the rubber component including the natural rubber and the polybutadiene rubber in a combined amount of 30 to 100 mass % per 100 mass % of the rubber component, the rubber composition containing, per 100 parts by mass of the rubber component, 20 to 80 parts by mass of the aromatic oil and 15 to 80 parts by mass of the silica, the rubber composition being prepared by mixing the natural rubber, the aromatic oil, and a masterbatch prepared by mixing the polybutadiene rubber and the silica.
