Abstract
Driving stability and durability is efficiently improved. Since a protecting layerembedded with reinforcing cordsis disposed between a treadand a belt reinforcing layer, both of the protecting layerand the belt reinforcing layerdecentrally bear a large bending force generated when a pneumatic tireruns on a sharp projection or a difference in level. As a result, even if reinforcing elementsin the belt reinforcing layerare extended by large tension due to fill internal pressure, increase of strain generated in the reinforcing elementscan be effectively suppressed.
