Actually toe in is the difference in the distance from a point on the tread
of a front tire when it is level with and in front the axle center to the to
the same position on the other front tire, compared with the same
measurement when that point is behind the axle.
It is best to mark and measure at one point then roll the car forward and
measure again to eliminate the effect of wonky tires or bent wheels.
Using your level system you should measure, then move forward half a
revolution and measure again, then average the results.

Subject: measuring toe-in
I'm measuring the Toe-in on my '56 BN-2. It is driving real nice but I just
wanted to make sure the toe-in was set within range.
I'm using a laser level that I purchased for 10$ and a 2X4. Just for kicks!
I'm getting a measurement of about 0.4 degrees and I think that corresponds
to around 0.09 inches toe-in.
My question is in regards to how the toe in is measured.
I guess it may seem obvious to some but, is it the distance that the forward
edge of the tire turns in relative to the center of the tire? I know that
some people measure the rear edge and compare that to the front edge but
then do they divide by two?
My laser level technique is kinda cool, if anybody is interested I can put
the procedure up on my website www.RickNeves.com
