MOBILE MEASUREMENT OF TRUCK TIRE TRACTION

A mobile dynamometer system has been developed for use in measuring the lateral and longitudinal traction properties of truck tires on actural paved surfaces. The apparatus is described, together with certain practices which are employed in its use. Data are presented covering basic characteristics measured with the longitudinal-testing portion of this apparatus. The data describe those sensitivities of truck tire traction which are of first-order relevance to the limit braking behavior of heavy trucks on dry pavements.
