To provide an automobile pneumatic radial tire satisfied in both noise suppression properties and tire durability.SOLUTION: An automobile pneumatic radial tire includes a carcass striding in a toroidal manner between a pair of bead parts and composed of a ply of a radial array cord. A section width SW (mm) and an outer diameter OD (mm) of the tire satisfies a predetermined relational expression. On an inner surface of the tire, one or more noise suppression bodies are provided. The noise suppression body is not provided on the inner surface of the tire in a region in an outer side beyond a 1/4 point in one of halves bordered by a tire equator plane in the tire width direction.SELECTED DRAWING: Figure 2

    【課題】本発明は、制音性とタイヤ耐久性とを両立させた、乗用車用空気入りラジアルタイヤを提供することを目的とする。【解決手段】本発明の乗用車用空気入りラジアルタイヤは、一対のビード部間でトロイダル状に跨る、ラジアル配列コードのプライからなるカーカスを備え、前記タイヤの断面幅SW(mm)及び外径OD(mm)は、所定の関係式を満たし、前記タイヤの内面に、1つ以上の制音体を設け、前記制音体は、タイヤ赤道面を境界とするタイヤ幅方向一方の半部における前記1/4点よりもタイヤ幅方向外側の領域での前記タイヤの内面には、設けられていない。【選択図】図2
