AOn an Mway, drive a set distance as shown by the "mileposts".20 MIles or 30 KM should do. Record the 'mileppst' readding at start and finish and odometer reading at the same times Compute and see how far the damn thinmg is off. Drvie 20k miles and repeat and see how much tyre diameter change has changed your error. Retired Safety Officer and car nut! |
