摘要：
在本发明中，在内压已经从标称内压P的0.05倍的内压状态增大到标称内压P时，点Pa、Ph、Pd以及Pe处的突出量分别表示为Da(mm)、Dh(mm)、Dd(mm)以及De(mm)。胎侧(6)的突出量之和Fa(((Dd+De)/W)×100)满足使用扁平率A的数学表达式(2)和(3)，并且胎面(4)的突出量之差Gs(((Da‑Dh)/W)×100)满足数学表达式(5)和(6)：0.02626×A‑1.8615﹤Fa(2)；Fa﹤0.02626×A‑0.6615(3)；‑0.010819×A‑0.084658﹤Gs(5)；Gs﹤‑0.010819×A+0.6713(6)。
摘要（英）：

In an internal pressure state where an internal pressure that is 0.05 times a normal internal pressure P has been increased to the normal internal pressure P, amounts of protrusions at points Pa, Ph, Pd, and Pe are represented as Da (mm), Dh (mm), Dd (mm), and De (mm), respectively. A sum Fa (((Dd+De)/W) × 100) of the amounts of protrusions for each sidewall 6 satisfies mathematical expressions (2) and (3) in which an aspect ratio A is used, and a difference Gs (((Da-Dh)/W) × 100) in the amount of protrusion for a tread 4 satisfies mathematical expressions (5) and (6).
