I'm waiting for my F07 (come with 18") and looking for a larger size wheels. Which size will you guys suggest? Any experience and comments for me?

People have put up to 22" wheels on this vehicle - as far as I know, 20" is the biggest available from the factory. Keep in mind that the vehicle is heavy, and larger tires wear faster (as they're almost always available only in higher performance versions). As long as you choose a wheel with the right offsets and internal clearances, and choose a tire with the same rolling diameter, your odometer and factory gearing will remain the same. A 22" wheel's tire on this vehicle is not much more than a rubber band - almost no height and the slightest bump is likely to damage it or crack the rim. Not all wheels will work with the TPMS, so you have to talk to a reputable source to verify they will fit properly. I'd start at www.tirerack.com, then branch out from there if I didn't find something I liked.

Personally, and BMW warns about this, larger tire/wheel combos are more prone to wheel/tire damage and the ride characteristics (IMHO) degrade. I like the stock 18" wheels...can't see them while driving, and I'm old enough not to care about what others think!

I think 20" or even 21" is a nice size on the 5GT.

20" is your best bet. Looks great without risking damaging it. I have 20's on my GT and love them. Check them out in my bio.

If go for the 22" rim, can 22" 9J ET36 (F) + 22" 10J ET36 (R) fit into F07.
how about tire size may i use 255/35/22 (F) + 295/30/22 (R)
or any suggestion, please.

remmib, thanks.
But i still wonder the rim can fit in or not,
as i count by Offset Calculators
(F) 9J ET36 vs 8J ET30 = 19mm LESS clearance on the strut side.
(R) 10J ET36 vs 8JET30 = 31mm LESS clearance on the strut side.

which the rear wheel should be fine, but the front have 19mm inner i fear will hits the frame.

Any suggestion ?

People that put such large wheels with short sidewall tires must either live in a near perfect world with billiard table smoothness, or don't drive their vehicle much...it's a cracked wheel waiting to happen situation IMHO. Good luck...I'd much prefer a vehicle I can drive reliably on typical roads.

Very happy with the 18 inch wheels. Much less chance of rim cracks with the run flats.

While 18"s are good for preventing cracks, both 18"s and runflats ruin the driving feel, as well as the look IMHO.

18"s make the car look ugly and monstrous, anything 20"s and above (with a drop) make it look much sleeker.

I'm going 21"s on my next GT.

Beauty is in the eye of the beholder, and I also will take function over beauty, at least up to a point. Being a big vehicle and given the roads I drive, I have no need or desire for higher performance tire/wheel combination. Add to that fact, I've got winter tires on it at least a third of the year may give you another indication of function. All season tires are a compromise all seasons, and summer tires are crap when it gets cold or there's even a hint of frozen stuff on the road. With freeze/thaw road issues, bigger wheels are a fools choice here as well. Plus, the narrower/higher profile stock rims and tires cut through the snow better.
