The Problem of Tire Sizes for Airplane Wheels
This is a 1932 NASA technical report, issued in the NACA technical memorandum series, on how airplane wheel tires should be sized, written for aeronautical engineers and aircraft designers. Its charts plot tire loading against deflection at different inner pressures in atmospheres, and its photographs show a tire compressed under load at successive stages. A designer could take from it the way tire bulge and deflection change as pressure rises, a useful reference for the shape of loaded tires in mechanical drawings.
