The object of the program was to develop basic, general, radial ply aircraft tire design parameters and construction techniques. Four (4) sizes of aircraft tires, 20x4.4/12, 30x8.8/22, 44x16/28 and 20.00-20/22 P.R. were selected for the study. A summary report of the literature survey and a design manual were issued for Phase I. A total of 81 tires were built of which 49 were tested. One 20x4.4/12 P.R. tire with revised tread shoulder configuration completed 200 mph qualification testing but the result could not be duplicated. Best performance was obtained on the 44x16/28 P.R. tires. An 8 actual ply 3 breaker tire completed 200 mph qualification testing. The principle mode of failure on dynamic tests was separation between the tread and breakers. Variations in the tread, breaker construction to improve dynamic performance were tested.
