Abstract
A pneumatic radial tire, particularly for a construction vehicle, has a carcass ply arranged toroidally between a pair of bead cores, containing rubber coated steel cords disposed radially therein, being turned up around each bead core from the inside to the outside of the tire and the turn-up portion of which around each bead core extends to around 1/2 height of the tire height H. When the radical length of an overlapping portion of the turn-up portion of the carcass ply and the main carcass ply is h.sub.1 and the thickness of the overlapping portion is w.sub.1 within a range of .+-.0.1 H having half height H/2 of the tire height H as the center, the radial length h and the thickness w of a reinforcing rubber material arranged between the turn-up portion of the carcass ply and the main ply satisfy the following formulae
