I was trying to say: unless a toe setting includes a toe span or an implied toe span (i.e. setting the car up on an alignment machine), it is unfortunately an almost meaningless number.
Is there a problem with using toe plates?

In other words, you are measuring to the face of the tire.
Lets do a thought experiment. Lets take the car to an alignment shop that has the latest and greatest alignment machine. It is so good, that it is perfect. Lets tell them to set the total toe at 1/8 of an inch or .125 inches. Now when they finish aligning the car you decide that you want to check and see how good this new alignment machine did. So you jack up the car and scribe the lines on the tires just as you describe. Assume for this example that the tire has a diameter of 27.04 inches. How well will the alignment machine check out to your method of measuring toe? Will you get the toe to measure .125 inches? No. I submit that you will read .118 inches of toe.
Now a completely separate argument could be made that this was close enough...
Sorry, I know doing the math can suck.
