tires) on a car? from 17's to 20's? I know it has something to do with larger tires taking longer to complete revolutions. Do the tire guys have to do something to the cars computer to make sure my speedometer reads correctly? Help me guys, I don't want the tire shop guys to try to take advantage of me. I need to have my facts straight. Chrysler 300 base. From 17's to 20's.
