Temperature Buildup and Radial Spring Rate Properties of Six Off-The-Road Tires

Temperature buildup tests and load deflection tests have been conducted on six tires; three sizes with one bias and one radial ply carcass construction per size. Temperature buildup curves are given for each tire at various conditions. Curves of load versus deflection are shown for each tire during both loading and unloading. Loss energies occurring during the loading-unloading cycle are tabulated.
