  • Radial ply aircraft tire and rim
    Patent number: 4813467
    Abstract: A radial ply aircraft tire (11) is mounted upon an H-type rim (10) which was originally designated for use with a bias ply aircraft tire. The ratio of the axial distance (WBF) between the rim flanges to the maximum cross-sectional width (CSWR) of the tire is in the range of 0.7 to 0.9. The ratio of footprint width to footprint length for the tire is in the range of 0.45 to 0.65. Preferably, the carcass (12) and the belts (14) are reinforced with aramid cords. A line (T) which is tangent to a carcass ply (12) and passes through the center of a bead (13) is inclined at an angle (.alpha.) of greater than 60.degree. with respect to the tire's axis of rotation.
