Abstract:
A pneumatic radial tire comprising; a pair of bead portions with a bead core therein, a pair of sidewall portions, a tread portion toroidally extending between both sidewall portions, a radial carcass reinforcing these portions and a belt reinforcing the tread portion at the outer circumferential side of the radial carcass, in which a thinned portion is formed in at least a part of each tire side portion located within a range of 0.5-0.8 times the carcass height (H) from the bead core at a state of inflating under an air pressure corresponding to 10% of the normal air pressure so that a minimum total tire thickness of this thinned portion as measured in the normal direction of the radial carcass at the meridional section of the tire is not more than 75% of a similarly measured minimum total tire thickness of the side portion located outside said range of 0.5-0.8 times the carcass height.
