ROLLING RESISTANCE OF PNEUMATIC TIRES

Potential improvements in tire power transmission efficiency are worth seeking for gaining improved automotive fuel economy. Summaries herein of tire rolling resistance as influenced by tire construction and design, tire materials, and tire operating conditions indicate clearly that current trends toward smaller, lighter automobiles and increasing usage of radial tires, in addition to reduced speed levels are positive contributions in their effort. Difficulties in obtaining accurate and relevant data are discussed, including the capabilities existing and new testing machinery, and the necessity for adopting standardized testing methods for tire rolling resistance.
