So i need some help. I have a 2009 550i that I will be putting E60 M5 style 166 wheels on. Tire size that i will be using will be 245/35/19 in the front and i have a choice of 275/30/19 or 285/35/19 in the rears. Which one of the rear sizes will work with no rubbing and look better? Also which size spacers do i need to use in the rears the get the best look and stance for the car? Also do i need to use spacers in the front? PLEASE HELP all info is appreciated Thanks

my choice was 285/30/19 in the rear on my 166's with no issues and a 12.5mm spacer in the rear.

there is a set of 166s with offsets meant for an M6 which has a lower offset. if you have that set you will not need spacers in the rear. if you have the M5 set, the rear offsets should be ET28 and a 12mm spacer would bring the wheels flush. if interested we do have 12mm spacers good in stock

How can you tell if i have the ones meant for the M6 or M5 and how much for the 12mm spacers? Also i heard you can you 10mm spacers what will that do?

Also if i have to use the 12mm spacer do you know which tire size would be better for the rear 275/30/19 or 285/35/19 ? Also the car is not lowered and i dont plan on lower it because i want the stock ride. I just want to get an idea whats the best set for these wheels to make them look good.

Thanks for all your help.

Do i need spacers for the front at all or leave it the way it is with a 245/35/19

info@trinityautosport

front offsets should be at ET12 on the OEM 166 wheels, so no spacers would be needed in the front
