looking at a set of 17" wheels with tires; I know the ideal size is 225/45, these wheels have 225/50. How much would that affect the accuracy of my speedometer?

Not by much. You'd probably lose the 3mph extra that is 'programmed' into it anyway.
Hah! So that's intentional? I always noticed that discrepancy when I pass those flashing speed limit signs that tell you how fast you're going. Thanks for that trivia tidbit :thumbup:

Don't know if it is intentional, but it's there. Mine is 5% off. A larger tire will throw the odometer and MPG reading off since the odometer is accurate on the car.
