A pneumatic tire having a tire profile equal to or less than 65, the pneumatic tire comprising: a pair of bead cores; a carcass layer that bridges between the bead cores in a toroidal shape; and a belt layer that is arranged on an outer side of the carcass layer in tire radial direction, characterized in that in a cross section of the pneumatic tire in tire meridian direction when the pneumatic tire is held without an external pressure to have tire base width equal to or more than 100[%] and equal to or less than 120[%] of a width of an applied rim, relationships 48 % ≤ HB / HA ≤ 52 %, 98 % ≤ HC / HA ≤ 100 %, 108 % ≤ WB / WA ≤ 115 %, and 55 % ≤ WC / WA ≤ 75 % are satisfied, where, when a straight line that is drawn from a position A of rim height FH in tire width direction is X-axis and a straight line that is drawn in the tire radial direction via center crown CL is Y-axis, WA is distance of a half of the tire base width, WB is distance from the Y-axis to a maximum width position P of the carcass layer, WC is distance from the Y-axis to an inflection point Q of the carcass layer, HA is distance from the X-axis to a peak R of the carcass layer on the center crown CL, HB is distance from the X-axis to the maximum width position P of the carcass layer, and HC is distance from the X-axis to the inflection point Q of the carcass layer, and wherein the inflection point Q of the carcass layer is positioned to satisfy 1%≤RA/RB≤10%, where RA is curvature radius of the carcass layer in a position on the outer side of the belt layer in the tire width direction and RB is curvature radius of the carcass layer in a position on the inner side of the position of RA in the tire width direction. a pair of bead cores; a carcass layer that bridges between the bead cores in a toroidal shape; and a belt layer that is arranged on an outer side of the carcass layer in tire radial direction, characterized in that in a cross section of the pneumatic tire in tire meridian direction when the pneumatic tire is held without an external pressure to have tire base width equal to or more than 100[%] and equal to or less than 120[%] of a width of an applied rim, relationships 48 % ≤ HB / HA ≤ 52 %, 98 % ≤ HC / HA ≤ 100 %, 108 % ≤ WB / WA ≤ 115 %, and 55 % ≤ WC / WA ≤ 75 % are satisfied, where, when a straight line that is drawn from a position A of rim height FH in tire width direction is X-axis and a straight line that is drawn in the tire radial direction via center crown CL is Y-axis, WA is distance of a half of the tire base width, WB is distance from the Y-axis to a maximum width position P of the carcass layer, WC is distance from the Y-axis to an inflection point Q of the carcass layer, HA is distance from the X-axis to a peak R of the carcass layer on the center crown CL, HB is distance from the X-axis to the maximum width position P of the carcass layer, and HC is distance from the X-axis to the inflection point Q of the carcass layer, and wherein the inflection point Q of the carcass layer is positioned to satisfy 1%≤RA/RB≤10%, where RA is curvature radius of the carcass layer in a position on the outer side of the belt layer in the tire width direction and RB is curvature radius of the carcass layer in a position on the inner side of the position of RA in the tire width direction.
