Abstract
A pneumatic radial tire in which a tread weight .alpha. per unit ground contact area is selected to be not greater than 1.80.times.10.sup.-3 kg/cm.sup.2, a cord reinforcing ply which extends up to a location outside of a top end of a bead filler in a radial direction of the tire is disposed in a bead portion and a cord angle .theta. of the cord reinforcing ply relative to a circumferential direction of the tire is selected to be 25.degree.-80.degree., a height RH of the cord reinforcing ply from a rim base up to the top end of the cord reinforcing ply, which is measured in the radial direction of the tire, is selected to satisfy the ratio, RH/SH=0.28-0.65, with SH being a cross-sectional height of the tire, and a height FH of the bead filler from the rim base up to the top end of the bead filler, which is measured in the radial direction of the tire, is selected to satisfy the ratio, FH/SH=0.11-0.28, with SH being the cross-sectional height of the tire.
