Thanks for the replies guys!!

Yes, I've considered the ride height will be about 1/2 - 3/4" taller (tire differences are about 1.5" diameter), however to conteract this I will be installing a full under body tray very soon. I like that my effective gear ratio will go down, also it's a narrower tire which is better for aero and the wheel covers will help too. I'm only worried about them being a lot heavier. Currently my wheels with tire weigh less than 25lbs each...

Oh and is there any way to correct the speedo? Or will I have to make my own corrections when doing MPG calculations?
