A pneumatic radial tire for a passenger vehicle. Said tire has a carcass comprising radial cord plies extending toroidally between a pair of bead parts. Radially outside of said carcass, said tire is provided with a belt and a tread in that order, said belt comprising one or more belt layers. This tire is characterized in that: if the section width (SW) of the tire is less than 165 mm, the quotient (SW/OD) of said section width (SW) and the outer diameter (OD) of the tire is 0.26 or less; if the section width (SW) of the tire is greater than or equal to 165 mm, the section width (SW) and the outer diameter (OD) satisfy the relation OD ≥ 2.135∙SW + 282.3; and letting V2 be the total volume of grooves formed in the surface of the tread and letting V1 be the volume of rubber that radially lies outwards of a radially-outermost reinforcement member in the widthwise center of the tire and widthwise lies inwards of the widthwise edges of the belt layer that is the widest in the width direction of the tire, V2 is at most 20% of V1.
