To provide an automobile pneumatic radial tire having improved noise suppression properties.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 and an outer diameter OD of the tire satisfies a predetermined relational expression. The noise suppression body is provided at least on an inner surface of the tire in a center region and a shoulder region. When a thickness of the noise suppression body is measured in a direction orthogonal to the inner surface of the tire, a maximum thickness Tc in the center region is larger than a maximum thickness Ts in the shoulder region.SELECTED DRAWING: Figure 2

    【課題】本発明は、制音性を向上させた、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及び外径ODは、所定の関係式を満たし、前記制音体は、少なくとも、前記センター領域及び前記ショルダー領域における、前記タイヤの内面に設けられ、前記制音体の前記タイヤの内面に直交する方向に計測した際の厚さは、前記センター領域における最大厚さTcが、前記ショルダー領域における最大厚さTsより厚い。【選択図】図2
