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).
