To provide a tire for a passenger car capable of being improved in wear resistance performance.SOLUTION: In a tire for a passenger car, tread rubber T07 comprises cap rubber T07C and base rubber T07B. The cap rubber is located on an outer side in a tire radial direction with respect to the base rubber and is located on both outer sides in a tire width direction with respect to the base rubber. The base rubber is composed of rubber having the same composition throughout the whole. A width of the base rubber in the tire width direction is less than a width of the cap rubber in the tire width direction. A storage modulus E' of the base rubber is 2.0 times or more higher than a storage modulus E' of the cap rubber.SELECTED DRAWING: Figure 1

    【課題】耐摩耗性能を向上できる乗用車用タイヤを提供する。【解決手段】乗用車用タイヤであって、トレッドゴムT07が、キャップゴムT07CとベースゴムT07Bとからなり、キャップゴムは、ベースゴムに対してタイヤ径方向外側に位置するとともに、ベースゴムに対してタイヤ幅方向両外側に位置しており、ベースゴムは、その全体にわたって、同じ組成のゴムから構成されており、ベースゴムのタイヤ幅方向幅は、キャップゴムのタイヤ幅方向幅よりも、短く、ベースゴムの貯蔵弾性率E’は、キャップゴムの貯蔵弾性率E’の2.0倍以上である。【選択図】図1
