HEAVY-DUTY PNEUMATIC TIRE

A heavy-duty pneumatic tire includes a carcass ply including a main portion extending between bead cores and a pair of turn-up portions, a first reinforcing layer (10) of a steel cord disposed in each bead portion in a U-shaped manner, and a second reinforcing layer (11) of an organic fiber cord disposed in each bead portion and at least a part of the second reinforcing layer (11) extending in a radial direction of the tire at an axially outward location of the first reinforcing layer (10). The second reinforcing layer (11) includes an axially inner second ply (11A) and an outer second ply (11B). The outer second ply (11B) has an inner end (20) positioned below the bead core. The inner second ply (11A) has an inner end (18) located axially inward of the inner end (20) of the outer second ply (11B), and has a substantially same length as the outer second ply (11B) in a tire cross-section.
