Jeff's suggested method is what everyone I know uses, and I've done it that
way for years myself. It is a superb method that works well and provides
accurate results. Do use the mold-marks Jeff mentions as measurement
points, it's the only way to get accurate and repeatable measurements.

It works well for me, especially in view of the fact I always get much
better than typical tire wear out of my big-a$$ tires.
