Thanks for your input everyone.

Zerochief: A few questions: Are the Style 87s considered BMW rims or is another manufacurer? What's the width on the staggered setup? Have you kept the stock brakes?

TurnAround and Bluedog: Can one of you guys post a web link to the 19" Style 132s? Would that be a staggered setup just like the 20" ones above?

I want to gather up as much info as possible in case I go ahead with a switch. FWIW, I just changed my Michelin Energy MXV4s (on the 18") after 31K miles as a precaution, but they still had PLENTY of tread left. I'm pretty sure they could have gone all the way to 50K. Would I get that much life on a 20" tire?

P.S. Villajoe: It's a Dinan exhaust
