摘要:
A heavy-duty pneumatic tire includes a section width being equal to or less than 335 mm, an aspect ratio being equal to or less than 55%, and a toroidal carcass extending between axially spaced bead portions through a tread portion and sidewall portions, wherein the carcass includes a carcass ply which includes a main portion and a turn-up portion, a belt layer disposed radially outward of the carcass in the tread portion, a sidewall rubber defining an outer sidewall profile of each sidewall portion, and a chafer rubber defining an outer bead profile of each bead portion, wherein in each bead portion, on a straight line that is perpendicular to the main portion of the carcass ply and passes a radially inner end of the sidewall rubber, the chafer rubber has a thickness of from 40% to 60% of a thickness of the bead portion.
