In the years I've been testing using a Racelogic V-Box GPS system, I've found most odometers to be witihin acceptable tolerances on standard tires... about 1-2%.

It's speedometers that are way off. Some over-reading by over 5 mph.

Pays to keep a GPS device in your car... or at least calibrate against a GPS device.
