Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a pneumatic radial tire for passenger car which has a low tire rolling resistance value (RR value), which is lightweight, and which has high air barrier property.SOLUTION: The pneumatic radial tire for passenger car of the invention has a large diameter, a narrow width, and its use inner pressure condition is regulated. The pneumatic radial tire has an inner liner whose dynamic storage elasticity is 500-8000 MPa at -40°C. 【課題】タイヤ転がり抵抗値（ＲＲ値）が低く、軽量化され、且つ高い空気バリア性を有する乗用車用空気入りラジアルタイヤを提供する。【解決手段】本発明の乗用車用空気入りラジアルタイヤは、大径化、狭幅化し、使用内圧条件を規定したものであり、かつ、−４０℃での動的貯蔵弾性率が５００〜８０００ＭＰａであるインナーライナーを備えるものである。【選択図】図８
