8.1 Determining Toe in and Out

Fig. 8-1
1. Inflate all pneumatic tires to recommended tire
pressures (listed on the sidewall of the tire).
2. Measure the distance between the center lines at the
rear and front of the rear wheels at approximately 12
inches from the ground/floor
For optimum accuracy, perform STEP 2 with the
racing chair occupied.
STEP 2 may be performed with using alignment
gauge (available as an option for the racing
chair).
3. Determine the difference between the two
measurements. If the difference between the two
measurements is greater than 1/4-inch (0 ± 1/8 inch for
maximum rollability), one of two conditions exists:
• If the rear centerline measurement of the rear
wheels is SMALLER than the front centerline
measurement of the rear wheels, a toe-out
condition exists.
• If the rear centerline measurement of the rear
wheels is LARGER than the front centerline
measurement of the rear wheels, a toe-in condition
exists.
4. If the difference between the measurements is greater
than 1/8-inch, correct the toe-in/toe-out condition.
