ABSTRACT:
There is provided a radial tire reducing rolling resistance by having a breaker cushion or a side wall packing comprising a rubber composition in which the loss tangent tan δ is reduced and the complex elastic modulus E* and the fracture feature are improved in good balance. A radial tire having a breaker cushion or a side wall packing comprising a rubber composition containing 20 to 55 parts by weight of carbon black having an iodine adsorption amount of 25 to 75 mg/g and a DBP oil absorption amount of 110 to 150 ml/100 g and 5 to 30 parts by weight of silica having a BET specific surface area of 115 to 200 m2/g based on 100 parts by weight of a rubber component.
