thinking of new wheels

kingka · 06-01-2009, 12:39 PM

I have stock e90 sports package wheels. 18" 225/40 front and 255/40 back (i think). I do not want to modify the ratio of the tire but i want to move up to 19". I hear that there will be an issue with the speedometer which makes sense. Can this issue be handled by re-calibration? and If yes, at the dealership? or can a tireshop do this?

TIA

use the calculator at the top of this page. And then search for plus sizing or search the forum..........

I'm pretty sure your not the first one to put 19's on your car

you don't need to re-calibrate your speedo because the 19's have a low profile tire that is almost equal to that of the stock 18 inch set up.
