This report describes a field test program aimed at quantitatively determining the changes in vehicle dynamics and driver response characteristics when radial, bias belted, bias ply, and lower pressure radial tire sets are intermixed on the front and rear of passenger cars. The driving tasks included highway lane tracking in the presence of simulated crosswind disturbances, transient tasks such as normal and emergency lane changes, and limit of control tasks such as a high-speed slalom. The results indicated that radial fronts with belted rears produced the greatest reduction in base vehicle understeer. Both this and a configuration with radial fronts and lower pressure radial rears were tested for time delay margins.
