Zusammenfassung:PROBLEM TO BE SOLVED: To provide a pneumatic radial tire capable of increasing the rigidity of a tire side wall part and improving the steering stability of the tire without impairing the riding comfort or the durability of the radial tire. SOLUTION: In this pneumatic radial tire having a rubber-filament fiber complex disposed on the side wall part, the rubber-filament fiber complex comprises filament fibers and a rubber component covering the fibers, the filament fibers include crystalline fibers having the strength of >=3.0 cN/dtex and at least repeating thick-thin structure, and the value of the thick-thin ratio (%)=(the diameter or the maximum of the maximum diameter of the filament)/(the diameter or the minimum of the maximum diameter of the filament)×100 satisfies the inequalities 105
