摘要： 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.

摘要： A heavy duty pneumatic tire having improved resistance to uneven tread wear includes a tread portion provided with an axially outer longitudinal main groove and an axially inner longitudinal narrow groove, each extending circumferentially about the tire to define a narrow rib therebetween, the axially inner edge of the narrow rib being chamfered by a slope. In the tire meridian section, the slope is straight or concave. The axial width of the axially inner longitudinal narrow groove is in the range of from 0.5 to 2.5 mm. The axial width (W3) of the slope measured between the upper and lower edges thereof is in the range of from 0.3 to 0.8 times the axial width (W2) of the narrow rib, and the radial height (H2) of the slope measured between the upper and lower edges is in the range of from 0.3 to 0.8 times the depth (H1) of the axially inner longitudinal narrow groove.
