text: Specifically, the cords of the reinforcing layer extending along the outside of the carcass ply are inclined on a circle formed by the upper end of the turn-up region of the carcass ply at an angle of 50° to 70° with respect to the radial plane of the tire and have an air gap ratio δ of 38% to 60% measured at a region where the cords of the reinforcing layer cross with a line tangent to a curved surface of a rim flange and extending in parallel with the rotary axis of the tire and given by the following formula ##EQU2## where b is a distance between the two midlines of two adjacent cords, measured perpendicular to the cords and c is a cord diameter.
