I just picked up a brand new 2012 335i Coupe with MSport suspension and am a noob when it comes to fitting aftermarket wheels. I've always been an OEM guy. But I am considering replacing my OEM 19" Style 230's with a set of gunmetal VMR710's on my NEW 2012 E92 with sport package and I have a question. My current tires are 225/35/19 on 19 x 8 wheels in front and 255/30/19 on 19 x 9 wheels in the rear. Will re-using my tires on the VMR wheels (8.5 in front and 10.0 in rear) stretch my tires too much such that I lose what little protection the rubber provides the wheels from curb rash? Will it leave my setup looking like the 20 year old kid with massive amounts of metal lip hanging way out there? I don't want that. I also don't want to buy new tires.

I am also considering some Avant Garde M510's and they come in 8.5 and 9.5. Would that be a better option if keeping my NEW existing tires is the priority?
