On my 03, I put 315's before the dealers even knew how to change rev's per mile, so he picked the 285 size. The odometer is off by 5. 8 % (calibrated by mileposts over 10 miles), and since most speedometers read 1-2 mph faster anyway (liability issue), I need to add 3 mph to the freeway speed, 2 mph in town. Not enough to get you a speeding ticket. I also need to add 1 mpg to the overhead.
I got used to it, and the warranty lasted a little longer.
