    • In a pneumatic tire of the present invention, a tread reinforcing rubber layer composed of a rubber having larger tensile modulus of elasticity than that of a rubber composing the tread rubber layer and is less stretchable is provided in a thickness direction central area of a tread rubber layer. Because the tread reinforcing rubber layer diminishes the amount of lateral expansion and the amount of vertical compressive deformation when the tread rubber layer contacts the ground, generation of heat in the tread rubber layer can be suppressed. Therefore, in the present invention, the unique tread structure reliably suppresses heat-generation and the rubber of the tread rubber layer exhibits excellent tire wear resistance. As a result, suppression of heat-generation and high tire resistance can readily be achieved simultaneously.
    • 在本发明的充气轮胎中,在胎面橡胶的厚度方向中心区域设有胎面增强橡胶层,该胎面增强橡胶层由具有比构成胎面橡胶层的橡胶的弹性拉伸弹性大的橡胶构成的伸缩性较小的橡胶, 层。 由于当胎面橡胶层接触地面时,胎面增强橡胶层减小横向膨胀量和垂直压缩变形量,因此可以抑制胎面胶层中的热量产生。 因此,在本发明中,独特的胎面结构可靠地抑制发热,并且胎面橡胶层的橡胶表现出优异的耐轮胎耐磨性。 结果,可以容易地同时实现发热的抑制和高耐轮胎性。
