Samenvatting
Miniature force transducers were used to measure (1) the cord stresses due to shaping tires during vulcanization, (2) the change in cord stress patterns caused by post-inflation, and (3) the cord loads caused by tire inflation and by cornering. Liquid metal gages were used to measure rubber strains on tire surfaces. A photo-elastic method was used to measure the strain distribution interior to the tire under simulated load. In each of these procedures, particular attention was given to the differences in properties among bias, belted bias, and radial ply tire.
