Abstract
A heavy duty radial tire comprises a radial carcass ply turned up around bead cores from the axially inside to outside of the tire, and a steel cord bead reinforcing ply disposed along the axially outer surface of the carcass ply turnup portion. The height of the carcass ply turnup portions is 1.5 to 3.5 times the rim flange height. The bead reinforcing ply extends so that the radially inner end is disposed on the radially inside of a straight line drawn between the axially inner extreme end and the axially outer extreme end of a bead core, and the radially outer end is spaced apart from the radially outer end of the turnup portion by a radial distance of from 5 to 20 mm. The radially outer ends of the turnup portions and the radially outer ends of the bead reinforcing plies are each covered with a cap made of hard rubber having a JIS-A hardness of 75 to 85 degrees.
