PROBLEM TO BE SOLVED: To provide a radial tire containing air for aircraft which is lightweight, prevents generation of a breakdown of a bead part due to a separation or the like at the junction of rubber members, and improves the durability of the bead part. SOLUTION: A rubber chafer and a second stiffener of the radial tire containing air for the aircraft are arranged between a point a and a point b. The rubber chafer has a coefficient of elasticityαof 3.1 to 4.6 MPa at the time of 100% elongation, and the second stiffener has a coefficient of elasticityβof 2.5 to 3.7 MPa at the time of 100% elongation. Then a linear dimension between the point a and the point c is expressed by the following formula, 0.24×(α/P) to 0.35×(α/P), and a linear dimension between the point b and the point c is expressed by the following formula, 1.69×(β/P) to 2.03×(β/P). Then an elasticity coefficientγof side rubber at the time of 100% elongation is 1.2 to 2.1 MPa, and a creeping distance between the point a and a point d on the tire surface is 15.6 to 64.2 % of the distance between a contact point A, which is a linear dimension on a rim flange, and a most outward point E of the rim flange.
