Abstract
The present invention aims to provide a tire having improved abrasion resistance and appearance, as well as reduced rolling resistance and therefore improved fuel economy. The present invention relates to a tire including a tread, the tread containing 0.9 to 1.5% by mass of a wax, 0.9 to 1.5% by mass of an amine antioxidant, 0.3 to 1.0% by mass of a quinoline antioxidant, and a tread rubber component containing 3% by mass or more of a polybutadiene rubber, the tread having a rubber thickness between a tread groove bottom and an outermost belt-reinforcing layer of 0.1 to 2.0 mm.
Claims3
A tire, said tire comprising a tread having a belt therein,
- the tread containing 0.9 to 1.5% by mass of a wax, 0.9 to 1.5% by mass of an amine antioxidant, 0.3 to 1.0% by mass of a quinoline antioxidant, and a tread rubber component containing 3% by mass or more of a polybutadiene rubber,
- the belt being disposed radially outward of a carcass of the tire and extending in a tire circumferential direction, the belt comprising a belt layer comprising a cord forming an angle with the tire circumferential direction of 15 to 30 degrees and at least one belt-reinforcing layer disposed radially outward of the belt layer, said belt-reinforcing layer comprising an organic fiber cord forming an angle with the tire circumferential direction of 0 to 5 degrees, and
- the tread having a rubber thickness between a tread groove bottom and an outermost belt-reinforcing layer of 0.1 to 2.0 mm.
