Old time alignment guys will tell you that toe-in is a TOTAL measurement. Think about the way Larry does toe-in. With regards to this, you can have perfect TOTAL toe-in with the tires turned 30 degrees, but the car won't go down the road straight. With the steering box locked at center, the tie rods are adjusted accordingly to give correct toe-in (& total toe-in) AND have a centered steering wheel.

HTH,
