Show Least Pull 
By pressing “Show Least Pull,” the placement of tire/wheel assemblies on the vehicle 
that will yield the least net tire pull will be shown. This positioning tries to place the 
two tire/wheel assemblies on the front axle that have the same amount of pull, but in 
opposite directions when on the vehicle. 
Lateral Force Results 
Lateral force of a tire will cause the tire to pull inward or outward. As long as the 
lateral force of one tire is pulling in an equal and opposite direction of the other tire on 
the same axle, the vehicle will travel in a straight ahead direction, whether the 
amount of lateral force is small or large. 
Show Least Vibration 
By pressing “Show Least Vibration,” the placement of tire/wheel assemblies on the 
vehicle that will yield the least vibration will be shown. This positioning will place the 
tire/wheel assembly with the greatest amount of road force on the passenger side of the 
rear axle (farthest from the driver). The tire/wheel assembly with the second highest 
road force will be placed on the driver’s side of the rear axle, and the tire/wheel 
assembly with the lowest road force will be placed on the driver’s side of the front axle. 
Show Alternate Placements 
By pressing “Show Alternate Placements,” the result of each of six different 
combinations of placements of tire/wheel assemblies on the vehicle may be 
previewed. The first screen shown will be the configuration that will yield the least 
amount of net pull. Each press of the “Show Alternate Placements” softkey will show 
the configuration that will provide the next least amount of net pull.
