There's a wheel calculator posted on to make the appropiate wheel calculations. https://g35driver.com/forums/wheels-tires/2130-wheel-size-calculator-rim-weights.html

I've never tried to install the TPS on my C4's (Let me know if it works). The tire light does come on every now and then, but it doesn't bother me. It's mainly off unless I've been driving for long drives. No biggie.

 

So the advantage of a 2 or 3 peice wheel is that they can be adjusted for different offsets?

Does that mean adjusted from the manufacturer or adjusted by ones own self?

Could someone make a list of the advantages/disadvantages of single peice or multi peice?
