5.9 Determining Toe In/Toe Out
1. Inflate all pneumatic tires to recommended tire pressures (listed
on the sidewall of the tire).
2. Measure the distance between the centerlines at the rear and
front of the rear wheels at approximately 12 inches (30.48 cm)
from the ground/floor.
For optimum accuracy, perform STEP 2 with the
wheelchair occupied.
If you have an alignment gauge, refer to 9.1 Using the
Alignment Gauge, page 65.
3. Determine difference between two measurements. If difference
between the two measurements is greater than 1/2-inch (1.27
cm) (0 + 1/4-inch (.63 cm) for maximum rollability), one of two
conditions exists:
•
If the back centerline measurement of the rear wheels is
SMALLER than the front centerline measurement of the
rear wheels, a TOE-OUT condition exists.
•
If the back 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
1/2-inch (1.27 cm), correct the toe-in/toe-out condition.
