ABSTRACT:
A pneumatic radial tire comprising an annular tread, a pair of sidewalls, an annular bead, a carcass, and an annular belt, when mounted on a standard rim to specifications and inflated with a standard pressure, staisfies the following condition:
.theta.1.ltoreq.30 degrees and .theta.2.ltoreq.30 degrees, wherein .theta.1 and .theta.2 are the acute angles formed by lines P1 and P2, respectively, with respect to an imaginary straight line D which extends radially from the axial outer end point (62) of a rim flange (61) in a plane containing the rotating axis of the tire, the lines P1 and P2 being tangential to the outer surface profile (22) of either sidewall at points E1 and E2 where the outer surface profile (22) intersects with the straight line D.
