Hey guys , I am a little surprised about the lack of response on my mileage post . I think it is significant that by putting bigger rims on a car your odometer will no longer give a valid mileage. If one of us were to buy a used car with aftermarket rims on the car and the car had 40000 miles , when in all reality depending on the size of the rims you could be getting a car with as low as 44000 or as much as 48000 with 20" rims. Buy wisely . Rich

Your speedo would be off as well - so in order to correct that you'd edit the ECU with the corrective factor, which in turn would correct the odometer.

Its not just the size of the rims, its how you use them. :histeric:
Seriously though, you can go with a low profile tire on a 20" rim and have the same wheel circumference as a taller tire on an 18" wheel. As long as they did the math correctly when resizing, there wouldn't be any issues.
