I have a 200 2.0 and I just put in 18" wheels with 40 profile tires... I now have a larger overal wheel/tire convo on my car. So my speed should be reading slower that it actually is...also affecting my milage reading. Does anyone know a site where it can give me my % of error?

Try this web site. You can input your stock wheel & tire size, your new wheel & tire size and it will calculate everything for you. I have a 1999 2.0 with 225/40/18's and the stock size was 205/55/16 so my speedo is actually reading a tiny bite slow. check out site it's very helpful. :D
