Instead, I would advise checking your speedometer against a GPS. My wheels were put on at the dealership, so I don't know it the speedometer was recalibrated or not; but with my 17" rims my speedo is spot-on.

On my Jeep I found putting on 2" larger tires actually made my speedo more accurate. It was optimistic beforehand, as are most...

You car also check the odometer against the highway mile markers.

I agree.. If you can hold your speed for more than a couple minutes (straightaway on flat level surface), GPSs can be VERY accurate at determining your speed.

My Yaris speedo is showing about 2.5 MPH too high on stock 15" wheels..
