Abstract
A pneumatic tireincludes: a tread; sidewalls; a carcass; and a belt. A distribution of a thickness Tg(y) of the tread in a region extending in an axially outward direction of the tire, is represented by equation Tg(y)=A−a×Ct(y). A represents a thickness of the tread at a crown center. Ct(y) represents a distribution of a displacement of the tread surface in a radially inward direction of the tire , in a region from the crown center to an end portion of the belt. a represents a coefficient selected from a range of values that are greater than or equal to 0.10, and are not greater than 0.35. A displacement Cc(y) of the carcassin the radially inward direction of the tire, in a region extending in the axially outward direction of the tire from the crown center, is represented by equation Cc(y)=(1−a)×Ct(y).
