Claim Text:
1. A pneumatic radial tire, characterized in that: in a cross sectional view in the tire widthwise direction thereof in a state where the tire is assembled with an application rim, inflated at a predetermined air pressure and mounted on a vehicle under a predetermined load exerted thereon, provided that: L radius of curvature (R a negative ratio of a ground-contact surface of the tread of a half portion, on the vehicle outer side with respect to the tire equatorial plane, of the tire when the tire is mounted on the vehicle is smaller than a negative ratio of a ground-contact surface of the tread of a half portion, on the vehicle inner side with respect to the tire equatorial plane, of the tire when the tire is mounted on the vehicle; an outer end in the tire radial direction of a turn-up portion around a bead core, of a carcass constituted of at least of one carcass ply, is disposed in each of the half portions of the tire at a height in the tire radial direction of at least 40% of the tire cross sectional height under no load exerted on the tire; and the tire cross sectional height (SH) as a height in the tire radial direction measured from the rim baseline to the outer diameter of the tire, of the tire side portion on the vehicle outer side, is smaller than the tire cross sectional height (SH) of the tire side portion on the vehicle inner side.
