Abstract
Tire traction on dry surfaces is discussed with emphasis given to the viewpoint of the vehicle-tire system engineer. The paper indicates that, in this context, the mechanics of shear force generation assumes greater importance than the detailed mechanisms that control the frictional coupling at the tire-road interface. After postulating a working definition to distinguish between the concept of “tire traction” and the mechanics of shear force generation, the latter process is described in phenomenological terms. Initial, early, and current efforts to define and measure the shear force mechanics of tires in their normative operating condition are briefly reviewed prior to presenting test results obtained recently in several research programs. These findings relate to (1) the manner in which the longitudinal and lateral components of shear force depend on the longitudinal and lateral components of slip, (2) the shear force/slip relationship as a function of tire geometry and construction, and (3) the sensitivity of peak lateral force to small amounts of tread shoulder wear.
