In a tire 2, a difference Fs (((Dd−De)/W)×100) in an amount of protrusion is greater than −0.4 and less than 0.5. A sum Fa (((Dd+De)/W)×100) of amounts of protrusions for a sidewall 6 satisfies mathematical expressions (3) and (4) in which an aspect ratio A is used, and a difference Gs (((Da−Dh)/W)×100) in an amount of protrusion for a tread 4 satisfies mathematical expressions (6) and (7). 0.02626×A−1.8615
