Re: Quick question - tire size
As said above, not a problem. I ran 255/60-17's for over 4 years without any rubbing. They are .492 inches shorter though, which throws the speedometer/odometer off a little. The diameter of the 255's is .492 in. less than the stock tires. When the speedometer is reading 65 mph, you're actually going only 63.9 mph.
IMO, the best bet would be to go with 265/60-17's, as the diameter difference is only .019 in., with the 265's being slightly shorter. At 65 mph indicated, you'd actually be going 64.95 mph. No much difference at all.
