Hunter Engineering Company authorized service personnel.

Setting Up the Runout & Road Force Limits
Selects the amount of road force and runout needed to exceed limits.
Setting the “P” Limits
The control knob changes the “P” (passenger) tire limits. Push the control knob in to
select the measurement limit you desire to change. For more restrictive passenger
tire limits, rotate the control knob counterclockwise. For less restrictive passenger tire
limits, rotate the control knob clockwise. The light truck and sport utility vehicle limits
are based on the limits set for the passenger tires. As the passenger tire limits
change, the corresponding “LT” and “P/SUV” limits will also change.
Setting the “P/SUV” Limits
The control knob controls the “P/SUV” (P-Rated tire on a Sport Utility Vehicle) tire
multiplier. The multiplier is a figure that is multiplied to the passenger tire limit to
obtain the “P/SUV” tire limits. For more restrictive “P/SUV” tire limits, rotate the
control knob counter-clockwise. For less restrictive “P/SUV” tire limits, rotate the
control knob clockwise. As the multiplier changes, all of the “P/SUV” limits will change
corresponding to the current multiplier.
