A construction vehicle tire comprising: a carcass body portion formed by a covered carcass cord; and a carcass folded portion continued to the carcass body portion and folded at a bead core from an inner side in a tire width direction toward an outer side in the tire width direction, the carcass folded portion being formed by a covered carcass cord, wherein a distance between cords, which is defined by a distance between the carcass cord of the carcass body portion and the carcass cord of the carcass folded portion, becomes smaller from the bead core toward an outer side in a tire radial direction to a minimum value a, and after the distance between the cords become the minimum value a, the distance between the cords becomes larger toward the outer side in the tire radial direction to the maximum value b, wherein the distance between the cords is defined by a distance between a center in a thickness direction of the carcass cord of the carcass body portion and a center in a thickness direction of the carcass cord of the carcass folded portion; and wherein, when the construction vehicle tire is mounted to an applicable rim and inflated to defined inner pressure according to a prescribed standard, a height HA of the carcass cord of the carcass body portion corresponding to the minimum value a from a base line of the applicable rim, a height HB of the carcass cord of the carcass body portion corresponding to the maximum value b from the base line of the applicable rim, and a flange height HF of the applicable rim from the base line of the applicable rim fulfill relations of 1.2 HF ≤ HA ≤ 2.5 HF 2.6 HF ≤ HB ≤ 3.5 HF 1.10 ≤ b / a < 1.40; characterised in that a crossing angle θ between a straight line SL1 passing a position of the carcass cord of the carcass body portion corresponding to the minimum value a and a position of the carcass cord of the carcass body portion corresponding to the maximum value b, and a straight line SL2 passing a position of the carcass cord of the carcass folded portion corresponding to the minimum value a and a position of the carcass cord of the carcass folded portion corresponding to the maximum value b fulfill a relation of 2.00 ° ≤ θ ≤ 5.00 °. a carcass body portion formed by a covered carcass cord; and a carcass folded portion continued to the carcass body portion and folded at a bead core from an inner side in a tire width direction toward an outer side in the tire width direction, the carcass folded portion being formed by a covered carcass cord, wherein a distance between cords, which is defined by a distance between the carcass cord of the carcass body portion and the carcass cord of the carcass folded portion, becomes smaller from the bead core toward an outer side in a tire radial direction to a minimum value a, and after the distance between the cords become the minimum value a, the distance between the cords becomes larger toward the outer side in the tire radial direction to the maximum value b, wherein the distance between the cords is defined by a distance between a center in a thickness direction of the carcass cord of the carcass body portion and a center in a thickness direction of the carcass cord of the carcass folded portion; and wherein, when the construction vehicle tire is mounted to an applicable rim and inflated to defined inner pressure according to a prescribed standard, a height HA of the carcass cord of the carcass body portion corresponding to the minimum value a from a base line of the applicable rim, a height HB of the carcass cord of the carcass body portion corresponding to the maximum value b from the base line of the applicable rim, and a flange height HF of the applicable rim from the base line of the applicable rim fulfill relations of 1.2 HF ≤ HA ≤ 2.5 HF 2.6 HF ≤ HB ≤ 3.5 HF 1.10 ≤ b / a < 1.40; characterised in that a crossing angle θ between a straight line SL1 passing a position of the carcass cord of the carcass body portion corresponding to the minimum value a and a position of the carcass cord of the carcass body portion corresponding to the maximum value b, and a straight line SL2 passing a position of the carcass cord of the carcass folded portion corresponding to the minimum value a and a position of the carcass cord of the carcass folded portion corresponding to the maximum value b fulfill a relation of 2.00 ° ≤ θ ≤ 5.00 °.
