or at least larger than stock rims... in that case even smaller rims than normal like some 10" spoked gold daytons bling bling! hah. Anyhow anyone ever calibrate their speedometer to reflect the difference in the reading? Is there even a way to do that? Or is everyone just estimating as to how far they have traveled/mpg after the wheels upgrades?

If you get the right size tires the speedometer will be pretty close from what I was told by my tire guy. They should be able to figure what profile to match the stock height pretty close. My stock wheel and tires were 225/50/16's and I have 225/45/17's on the front and 245/40/17's on the rear. Both sizes are very close to the stock height.

CRE: How? Interested as well, as I just put 17" Mustang GT wheels with 245 55's on, and my speedo is definitely off.

CRE: Thanks for the link :) Need to pull my cluster to fix a squeaky cable anyway, so I can do this at the same time. A whole lot cheaper than buying tires, to....

As far as changing tire size to compensate, I already plan on that(to a degree, I hate really short sidewalls: they look really bad), just wanted to know how to recalibrate the speedometer.
