Abstract
It is generally accepted that steering axle tire wear rates are considerably higher in turns than in a straight ahead condition. Ackerman correction accounts for the different turning radii of the left and right steering axle tires in a turn but does not take into account slip angle. Slip angle is a significant factor in tire wear. “Optimum Ackerman” does take slip angle into account and should theoretically reduce tire wear. Theory, simulations, and field results are presented.
