Plus Sizing your rims

[Jester236]

So a question to those of you that have gone from a 14 inch rim on a protege to a larger one. How much was your speedometer and or odometer affected? I believe that low-profile tires would help keep the margin down, but I wanted to know if anyone has any specifics. Thanks.

I have about a 1% difference between the speedo and the actual speed according to my GPS and the lovely radar signs they put around town. Pretty much negligible, unless you're doing well over the speed limit, but then it doesn't really matter, huh!?

Thanks for the link and info.
