How to calibrate speedometer for bigger wheels?
I know this isnt really engine tech but I just put 18" wheels with 225/40/18 tires and was wondering how to calibrate the speedometer for my car so that /i know how fast I am going. Any help would be great.

your speedo will only be a few mph off. I just did a quick check here http://www.miata.net/garage/tirecalc.html and it looks like you'll only be 3.6% off. So when your speedo is at 60, you'll be going 62.2, no big deal IMO
