ABSTRACT:
The ground contact pressure on land portions44is uniformed so that drivability is improved and uneven wear is suppressed to improve wear resistance. The parts of the carcass layer28and belt layer33overlapping with the main grooves42are convexly curved toward the outside in the radial direction due to the internal pressure. The reinforcing layer49is arranged at the position spaced from the neutral axis of deformation in the compressed side in a certain distance, i.e. radially inside of the radially outermost carcass ply30, and the steel cords47which extend in the direction including the tire width direction and its approximate direction and which act as supports for resisting against the compression force are embedded in the reinforcing layer. As a result, the above-mentioned curved deformation can be effectively suppressed.
