A radial tire has a carcass ply (17) with turn-up portions (19) extending around each bead (13). On the side of the carcass ply (17) furthest away from each bead (13) are located two reinforcing plies (21,22). Each reinforcing ply (21,22) has portions (21A,22A, and 21B,22B) disposed on each axial side of the associated bead (13). The first portions (21A,22A) of the reinforcing plies adjacent the carcass ply turn-up portions (19) extend radially outwardly thereof, and the second portions (21B,22B) of the reinforcing plies on the other axial side of the bead extend radially outwardly beyond said first portions (21A,22A). |
