I am in the process of trading off my stock 2002 330i sedan wheels for a stock set from a 2003 330cic. As far as I can surmise, these are the same width and 'offset'. Am I correct?
What exactly is offset anyway? How far the tire is left or right vs the hub?
One more question - I was going to put Pirellii Pzero M+S on the 4 wheels and was thinking about the optional wider tire (same as the ZHP front). If I do this, and my fullsize spare is the OEM wheel and tire, is this a dangerous situation if I have to run the spare upon getting a flat?
Any other disadvantages of the wider tire? I really don't look forward to lower mileage or heavier tramming (but the pirellis do not come in the OEM width).
