A plurality of circumferential main grooves extending circumferentially within the tread tread surface, an organic fiber belt within the tread crown, and a tire extending at a relatively small angle in the circumferential direction. In a pneumatic radial tire having at least two belt layers intersecting with each other, main grooves sandwiching the tire center and disposed axially outward of the tire at least 50% of the ground contact width under load. The groove bottom blocking protrusions are arranged at substantially equal intervals around at least the corner of the groove bottom near the tire shoulder, and the circumferential spacing of the protrusions is 10 times the ground contact length under load.
% to 90%, and the groove depth is 20% to 80% of the main groove depth from the groove bottom. 2.
