AIR-FILLED RADIAL TIRE

Provided is a pneumatic radial tire having improved pinch cut resistance without increasing the weight of the tire. The radial tire has a rubber chafer 7 arranged on the carcass ply in an contacting area of a bead portion with an applicable rim; a bead filler 8 arranged radially outside on the bead core; and a side rubber 13 extending along an outer surface of the carcass in each a side wall portion. In a state where the tire is mounted on an applicable rim R and inflated with a predetermined pneumatic pressure, an outer end 6a of the folded portion 6 of the carcass and an outer end 8a of the bead filler 8 are placed inward from an outer end r of a rim flange Rf of the applicable rim R in the radial direction; an outer end 7a of the rubber chafer 7 is placed outward from the outer end r of the rim flange Rf in the radial direction; and at least a part of a side rubber 13 located outward from the outer end of the rim flange Rf in the radial direction is disposed between the rubber chafer 7.
