| 简介 |
Provided is a pneumatic tire including a tread formed from a specified rubber composition, thereby achieving a balanced improvement in fuel economy, wet-grip performance, and abrasion resistance while simultaneously having excellent durability. The present invention relates to a pneumatic tire including a tread formed from a rubber composition, the rubber composition containing : an oil-extended BR having a cis content of 95 mol% or more, a vinyl content of 1 mol% or less, and a weight average molecular weight of 530, 000 or more; a SBR having a bound styrene content of 30-50% by mass and a weight average molecular weight of 700, 000 or more; silica; and carbon black, the oil-extended BR being synthesized using a rare earth catalyst, the rubber composition containing, based on 100% by mass of rubber solids, 10-67% by mass of the BR component contained in the oil-extended BR and 10-50% by mass of the SBR. |
