ABSTRACT:
A heavy duty pneumatic radial tire is disclosed, having bead portions with an improved durability. The tire is provided with a carcass of at least one ply, including a carcass body extending between both bead portions of the tire, and turn-up portions which are contiguous with the carcass body and arranged around and radially outwardly of bead wires. In a particular radial region of the tire, the distance G between center lines of the carcass body and the turn-up portion of the carcass is optimized in accordance with relevant dimensional parameters of the tire, to minimize strains and suppress separations in the bead portions.
