PROBLEM TO BE SOLVED: To provide a pneumatic radial tire capable of improving in lopsided wear performance and fraction performance while maintaining draining and cornering performance. SOLUTION: A main wide groove 2 is arranged on the outer periphery of a tread 1 to be offset from a crown center C to a tire inside area during mounting on a vehicle, the main wide groove 2 having a groove width W1 twice or more a groove depth D and having an sectional shape with the angleα1 of an inside groove wall 21 during mounting on a vehicle set to be within 1.5-4 times the angleα2 of an outside groove wall 22 during mounting on a vehicle. A groove wall end 22a is set to be located in a tire inside area during mounting on a vehicle and a groove wall end 21a is set to be located a distance 35% a tread width from the crown center C. |
