    • W is the width of the belt layer 5a in the innermost side in the tire radius direction. A is the region of the belt reinforcing layer 11 which is the region at the both sides of the tire equator plane 30 in the tire width direction. B is the region in the outer side of the region A in the tire width direction. C is the region that is further outer side of the region B. Ma, Mb and Mc are tensile modulus per inch of the region A, B and C respectively. The width Wa of the region A is 2 to 10% of W, the width Wb of the region B is 15 to 40% of W, Mc is 350 to 2000N, Ma is 100 to 400% of Mc, Mb is 200 to 800% of Mc, and Mb is larger than Ma.
    • W是轮胎半径方向上最内侧的带束层5a的宽度。 A是作为轮胎赤道面30的轮胎宽度方向的两侧的区域的带束层增强层11的区域。 B是轮胎宽度方向上的区域A的外侧的区域。 C是区域B的另外的外侧的区域.Ma,Mb和Mc分别是区域A,B和C的每英寸的拉伸模量。 区域A的宽度Wa为W的2〜10%,区域B的宽度Wb为W的15〜40%,Mc为350〜2000N,Ma为Mc的100〜400%,Mb为200〜800 Mc的百分比,Mb大于Ma。
