TIRE TRACTION GRADING PROCEDURES AS DERIVED FROM THE MANEUVERING CHARACTERISTICS OF A TIRE-VEHICLE SYSTEM. VOLUMES I AND II (COMBINED)

The report contains: (1) wet-surface longitudinal and lateral shear-force data for 10 tires which differ in construction and/or state of treadwear; (2) rank difference correlations between tire traction quality rankings derived from tire testing and tire rankings derived from tire-vehicle system tests; (3) a comprehensive tire shear force model and a mathematical method for fitting tire data (these are included in Vol. II) and (4) results from analyses and simulation studies of tire-vehicle system performance in J-turns and locked-wheel diagonal braking stops.
