To provide a pneumatic tire capable of suppressing generation of groove cracks.
In this pneumatic tire 1, relationships among the width WA of a half of the tire base width, a distance WB from a Y axis to the maximum width position P of a carcass layer 3, a distance WC from the Y axis to an inflection point Q of the carcass layer 3, a distance HA from an X axis to a top R of the carcass layer 3 in a center crown CL, a distance HB from the X axis to the maximum width position P of the carcass layer 3 and a distance HC from the X axis to the inflection point Q of the carcass layer 3 are defined as 48[%]HB/HA52[%], 98[%]HC/HA100[%], 108[%]WB/WA115[%], and 55[%]WC/WA75 [%], in the cross sectional view in the tire meridional direction when the tire is held as a single body, such that the tire base width becomes 100[%] and 120[%] of the rim width of an applied rim.
