A pneumatic tire comprising: a tread that comes into contact with a road surface; a band located radially inward of the tread; and a belt located radially inward of the band and including at least two layers (46a, 46b) stacked in a radial direction, wherein each layer (46a, 46b) included in the belt includes a large number of belt cords aligned with each other, the band includes a band cord extending substantially in a circumferential direction, the band is a full band that covers an entirety of the belt, on a cross-section, along a plane including a rotation axis, of the tire in a state where the tire is mounted on a normal rim, an internal pressure of the tire is adjusted to 10% of a normal internal pressure, and no load is applied to the tire, wherein the normal rim means a rim specified in a standard on which the tire is based and the normal internal pressure means an internal pressure specified in the standard on which the tire is based, an outer circumferential surface of the tire has a profile that is convex radially outward, the profile includes a center portion including an equator of the tire, a pair of middle portions each located outward of the center portion in an axial direction, and a pair of side portions located outward of the middle portions in the axial direction, respectively, the center portion is represented by a circular arc having a radius TR1, each of the middle portions is represented by a circular arc having a radius TR2 smaller than the radius TR1, and each of the side portions is represented by a circular arc having a radius TR3 smaller than the radius TR2, and a ratio of the radius TR1 of the circular arc representing the center portion, to a width of the tread, is not less than 4.94 and not greater than 5.21, characterized in that the full band has a width larger than the width of the tread, the band cord is a cord formed from a polyethylene terephthalate fiber and a load at 4% elongation of the band cord is not less than 60 N, wherein the load at 4% elongation of each band cord is measured according to the test method for "load at constant elongation" specified in JIS L 1017. a tread that comes into contact with a road surface; a band located radially inward of the tread; and a belt located radially inward of the band and including at least two layers (46a, 46b) stacked in a radial direction, wherein each layer (46a, 46b) included in the belt includes a large number of belt cords aligned with each other, the band includes a band cord extending substantially in a circumferential direction, the band is a full band that covers an entirety of the belt, on a cross-section, along a plane including a rotation axis, of the tire in a state where the tire is mounted on a normal rim, an internal pressure of the tire is adjusted to 10% of a normal internal pressure, and no load is applied to the tire, wherein the normal rim means a rim specified in a standard on which the tire is based and the normal internal pressure means an internal pressure specified in the standard on which the tire is based, an outer circumferential surface of the tire has a profile that is convex radially outward, the profile includes a center portion including an equator of the tire, a pair of middle portions each located outward of the center portion in an axial direction, and a pair of side portions located outward of the middle portions in the axial direction, respectively, the center portion is represented by a circular arc having a radius TR1, each of the middle portions is represented by a circular arc having a radius TR2 smaller than the radius TR1, and each of the side portions is represented by a circular arc having a radius TR3 smaller than the radius TR2, and a ratio of the radius TR1 of the circular arc representing the center portion, to a width of the tread, is not less than 4.94 and not greater than 5.21, characterized in that the full band has a width larger than the width of the tread, the band cord is a cord formed from a polyethylene terephthalate fiber and a load at 4% elongation of the band cord is not less than 60 N, wherein the load at 4% elongation of each band cord is measured according to the test method for "load at constant elongation" specified in JIS L 1017.
