Wheel Calibration Tool

I have my track wheels at 18" on the front and 19" on the back. It throughs the speedometer off by about 5 mph while driving and then more on the track at higher speeds. Has anyone use some OBD 2 tool to change the tire sizes? I would like to be able to change back and forth as I switched the wheels. Thanks for any guidance.

Why do you need a speedometer on the track? Just curious...

I don't think I've seen where you can change the tire diameter on the biderectional scanners but can maybe check tomorrow when I'm in my shop.

LOL, it is that tricky drive to and from the track that will get you. Especially leaving the track as the local boys don't appreciate you still doing over 100.
