PROBLEM TO BE SOLVED: To provide a pneumatic radial tire for a two-wheeler capable of maintaining the driving force and the steering stability performance by suppressing the braking force generated in the tire grounding surface during the deep turn in which a vehicle is largely inclined. SOLUTION: In the pneumatic radial tire 10 for the two-wheeler, a bead core 20, a bead part 18, a carcass 16, a spiral belt layer 22 on the outer side in the tire radial direction, a crossing belt layer 26, and a tread 28 are arranged in this order. The distance X1 from the tire axis to the center line L1 in the thickness direction of the spiral belt layer 22 and the distance from the center line L1 to the surface of the tread 28 are reduced on tread 28 end side more than the tire equatorial plane CL side, and the distance from the center line L2 in the thickness direction of the crossing belt layer 26 to the center line L1 is reduced on the tread 28 end side more than the tire equatorial plane CL side. Thus, the braking force generated in the grounding surface during the turn of a vehicle can be suppressed, the driving force can be maintained, and the steering stability performance can be maintained.
