NOTE
Vehicle must be on level ground with wheels set straight ahead.
Steps 1 through 3 will determine centerline of tire.
“Point of Measurement” for checking toe-out will be where lines
marked in steps 1 and 3 intersect.
Mark line (4) on center tread (1) of tire (2) 16-3/2 in. (42 cm) from ground.
Measure total width of tire tread (3) and record.
Mark line (5) on center tread (1) at one-half total tread width (3).
Repeat steps 1 through 3 for opposite tire.
Measure distance between “Points of Measurement” on front side of tires (2) and record.
Rotate tires (2) by moving vehicle forward until “Points of Measurement” are 16-1/2 in. (42 cm)
above the ground at rear side of tires (2).
Measure distance between “Points of Measurement” on rear side of tires (2) and record.
NOTE
If measurement is larger on rear side of tires than measurement
on front side of tires, tires have toe-in.
If toe-out alignment does not meet specifications, repeat
checking procedures to eliminate any possible reading errors.
Subtract measurement from rear side of tires (2) step 7, from measurement from front side of
tires (2) step 5. The result of this subtraction represents inches of toe-out. Refer to table 8-2 for toe-
out specifications. If toe-out does not meet specifications, adjust toe-out (task c). Refer to table 8-2
for toe-out adjustment specifications.
If toe-out is within specifications, refer to (task c), and perform step 5.
NOTE
Vehicles should be at curb weight to ensure proper alignment. Refer
to table 8-2(a.) for adjustment specifications.
Table 8-2(b.) is optional and can be used when the vehicle’s average
operation is at less than gross vehicle weight. Vehicle is to be loaded
to its average operating weight when using this table.
