Abstract

Mobile apparatuses have been constructed and employed to evaluate the shear forces produced by pneumatic tires on actual paved surfaces. These devices have permitted extensive examination of tires designed for service on passenger cars and on light and heavy trucks. Considerations of system design and mobile test methodology are discussed as they constitute a special interest within tire test technology. The specific design characteristics and capabilities of mobile traction test machines developed at the Highway Safety Research Institute are discussed. Example data are presented illustrating the characteristic measurements for which mobile techniques are most suitable.
