To provide a pneumatic radial tire for heavy loading which can be lightened while sufficiently securing durability around a bead.

The rolling up part 2B of a carcass layer 2 approaches extremely the body part 2A of the carcass layer 2 from a position S separated from a bead core 3 toward a rolling up end 2e and distance from the center C of the bead core 3 to the rolling up end 2e is set to 40 mm or more, and also while a hard rubber layer 6 is arranged as a bead filler in a range on a bead core peripheral side held by the rolling up part 2B and the body part 2A, soft rubberlayers 7a, 7b softer than the hard rubber layer 6 are arranged in the peripheral range of the rolling up end 2e and a rubber gauge (t) between the rolling up end 2e and the body part 2A is set within the range of from 1 to 5 mm.
