You are doing a four-wheel alignment on a customer’s vehicle.  During the alignment, you made the following toe measurements.

Tire

Distance from centerline of vehicle to

Calculate tire toe

 

	Centerline of the tire at the front of the tire (A)	Centerline of the tire at the rear of the tire (B)	A – B
Right Front	71.3079 cm	71.8921 cm
Left Front	71.8413 cm	71.3587 cm
Right Rear	71.9048 cm	71.2952 cm
Left Rear	71.4984 cm	71.7016 cm

a.  Complete the table by calculating the toe on each tire.  Express answers in millimeters.

b.  Calculate the total toe on the front end by finding the sum of the right front toe and the left front toe.

c.  Calculate the total toe on the rear end by finding the sum of the right rear toe and the left rear toe.

 Solutions:

   a. 

Calculate Tire Toe

A – B

–5.842 mm

4.826 mm

6.096mm

–2.032 mm

b.   Total toe on front end = –5.842 mm + 4.826 mm
Total toe on front end = –1.016 mm

c.      Total toe on rear end = 6.096 mm + (–2.032 mm)
 Total toe on rear end = 4.064 mm
