A COMPARISON OF LABORATORY AND HIGHWAY TIRE ROLLING RESISTANCE TESTS
Rolling resistance measurements on the 1.7 m. roadwheel and Clayton twin roll simulator, and outdoor fuel consumption and coastdown test results were compared for tires specially formulated to illustrate differences. Twin roll results correlate poorly with other test results, especially for grouped radial and bias tires. Thermal analysis showed that the twin roll test accentuates the tread region more than the 1.7 m. test. Equations including tire type and tread and sidewall hysteresis provide a good correlation between the twin roll and the other test methods. The Clayton twin roll simulator has become an important apparatus for measuring and specifying tire rolling resistance since it simulates tire deformation on the Clayton dynamometer used in Environmental Protection Agency fuel consumption tests. If raw Clayton simulator rolling resistance data are used for developing low rolling resistance tires, the results can be quite misleading; the resulting tires will not necessarily be the best for minimizing fuel consumption.
