A pneumatic tire for heavy duty having an aspect ratio of 65% or less comprising: a tread portion; a pair of bead portions; a carcass extending from one of the bead portions to the other one of the bead portions via the tread portion; and a belt layer arranged inside the tread portion, wherein the tread portion includes a plurality of circumferential grooves extending continuously in a tire circumferential direction, the circumferential grooves include a pair of shoulder circumferential grooves and at least one crown circumferential groove arranged between the shoulder circumferential grooves, each of the shoulder circumferential grooves is a wide groove that does not close when contacting the ground under the condition of being loaded with the maximum tire load, the belt layer includes a plurality of belt cords made of metal and arranged obliquely with respect to the tire circumferential direction, and a pair of outer ends in a tire axial direction of the belt layer are each positioned axially outside a respective one of the shoulder circumferential grooves, characterized in that the crown circumferential groove is a narrow groove that closes when contacting the ground under a condition of being loaded with a maximum tire load when the tire is mounted on a standard rim and inflated to a standard inner pressure, wherein the standard rim is a wheel rim specified for the tire by a standard included in a standardization system on which the tire is based, and the standard inner pressure is an air pressure specified for the tire by a standard included in a standardization system on which the tire is based, and wherein the maximum tire load is specified for the tire by a standard included in a standardization system on which the tire is based, and a belt half width from a tire equator to one of the outer ends of the belt layer is 55% or more and 85% or less of a carcass half width, the carcass half width being a distance in the tire axial direction from the tire equator to the carcass at a maximum tire width position in an axial half of the tire. a tread portion; a pair of bead portions; a carcass extending from one of the bead portions to the other one of the bead portions via the tread portion; and a belt layer arranged inside the tread portion, the tread portion includes a plurality of circumferential grooves extending continuously in a tire circumferential direction, the circumferential grooves include a pair of shoulder circumferential grooves and at least one crown circumferential groove arranged between the shoulder circumferential grooves, each of the shoulder circumferential grooves is a wide groove that does not close when contacting the ground under the condition of being loaded with the maximum tire load, the belt layer includes a plurality of belt cords made of metal and arranged obliquely with respect to the tire circumferential direction, and a pair of outer ends in a tire axial direction of the belt layer are each positioned axially outside a respective one of the shoulder circumferential grooves, the crown circumferential groove is a narrow groove that closes when contacting the ground under a condition of being loaded with a maximum tire load when the tire is mounted on a standard rim and inflated to a standard inner pressure, wherein the standard rim is a wheel rim specified for the tire by a standard included in a standardization system on which the tire is based, and the standard inner pressure is an air pressure specified for the tire by a standard included in a standardization system on which the tire is based, and wherein the maximum tire load is specified for the tire by a standard included in a standardization system on which the tire is based, and a belt half width from a tire equator to one of the outer ends of the belt layer is 55% or more and 85% or less of a carcass half width, the carcass half width being a distance in the tire axial direction from the tire equator to the carcass at a maximum tire width position in an axial half of the tire.
