I've only had my car for a week, and I'm already considering my first mod.... 19" OEM style 166 wheels. My car currently has the stock 18" sport package wheels w runflats. Not knowing anything about wheels and how they work, is there anything I need to consider? Will the OEM 166's fit properly on a 545i by just bolting them on, or is there something else I need to do? Will the different size wheels affect the speedometer/odometer readings, and does an adjustment need to be made to those? I notice that the 166 rear tires are wider than the front ones... is this a problem? What other questions should I ask the tech?
If anyone who has replaced stock 18's with 166 19's can guide me through it, I'd appreciate it. Thanks!

there's nothing wrong with a staggered set-up. you just wont be able to rotate the wheels. yes they will fit perfectly on a 545 but not with the tires of an M5. recommended tire sizes are 245/35/19 front and 275/30/19 rear. the offsets of the oem 166s i believe are front ET12 and rear ET28. they will fit, but if you want the rear wheels to be flushed with the rear fender, and for a more wider stance, you could add 12mm spacers. and also for a better ride, no more runflats. hope this helps.

So if I go with 245/35/19 front and 275/30/19 rear tires they will fit okay? Since I can't use the M5 tires, what brand/model of tire would you recommend. Can I get the 12mm spacers from BMW, or are they aftermarket. and are they needed on all 4 tires or just the front?
Thanks.

I also recommend lowering your car when you get new wheels..

Thanks.
Since you have sport package, you may get back without lowering it. Personally I won't lower it since although it looks nicer, it's quite easy to scrap the bottom of the front bumper... I don't have SP so it's almost a must to lower it with a 19" combo.

If I were you just side step the 19" and go straight to 20" wheels.

Yeh i have 20in wheels, looking stunning on lowered eibach springs, however the ride is a bit choppy on bumby roads, otherwise no real concern
in the latest PBMW magazine this month i saw a E63 645i with 26in spinners....!!!!!!!!!

My setup (described below) is pretty standard, except that most get the 15mm spacers instead of 20mm.
Looking back, I think that 20" is the way to go to really make an impact, but my 19" wheels are nice too.
