Hi 2Addicts,

I'm a new owner of my alpine white f22 m240i.

I have a brand new set of 18x9 +42 square set of wheel originally for my e82 135i, but this car has taken the spotlight and I wanted to see what the scope was like to put these on.

- Tire Size Options - I was considering Michelin PS4s (they do run thicker)
- Suspension Clearance Requirements (camber, etc)
- Body Modification (Rolling/Pulling Fenders)
- Spacers (mm size?)

This car will be a street and fun road driver for me.

I was only able to find info here about this set up here:

https://apexwheels.com/fitment-guide...-fitment-guide

"Front & Rear: 18x9" ET42 with 255/35-18 tires
Available in: ARC-8
8mm front spacers required (hub extender required).
Additional front negative camber recommended. At least -2.5° is required for 200 or lower TW tires that run wide.
Additional rear camber or fender rolling may be required with tire models that run wide."

Hope someone has tried this or can give me guidance. If not, I will find a used tire and try to test fit in the next week.

All help is appreciated. Thanks!

Front

Note: fitting wide front tires on this car is a principal downside of ownership

I have Apex 18X9 ET42 ARC-8 wheels in the front with 255/35-18 PS4S tires on them. The fenders are rolled slightly and the camber is -2.6°. I have hub extenders and 8mm spacers installed, too. The fit is entirely satisfactory on my lowered car. (Pics here (note the 17X9 ET42 in front), although with different 255 tires: https://www.2addicts.com/forums/show...2&postcount=18).

The negative camber was achieved via camber plates that came with a coilover kit I bought for the car. Because there's not much room in front (made worse when lowering it 1¼", as I did), I recommend contacting Harold at HP Autosport (HP Autosport) if you plan on installing coilovers. Harold has a list of coilovers that offer more room in front than do other coilovers.

Rear

I have Apex's 18X9½ ET58 ARC-8s with 5mm spacers back there and the same 255/35-18 PS4S tires. Those fenders are also rolled slightly, the camber is -2.3°, the rear is lowered 1", and the fit isn't an issue.

I'm afraid I'm not conversant enough with this stuff to say how well and under what circumstances 18X9 ET42s with the 255 PS4S would fit in back. My guess is that it will work. It might be worth a call to Apex, or to Harold, as this is their world. Other members may have useful and specific input, too, of course. My solution was to take my car to a shop that does only this sort of thing and only for BMWs.

Note that the BMW-specific Michelin Pilot Super Sport tires in 245/35-18 that came on the car when delivered have a tread width of 9.2" and a section width of 9.7", and the non-BMW specific PS4S tires in 255/35-18 have a tread width of 8.8" and a section width of 10.2". If I'd known this before I bought the PS4S 255s, I would have chosen the 245 PSS tires for the greater amount of tread where the rubber meets the road.

I ran this exact setup on my 228i. Because I had coilovers, I ran the setup with a 12mm spacer in the front and can confirm that at least -2.5 degrees of camber was necessary in order to clear the fender. I ran millway street plates in order to achieve the camber gain. I went with extremecontact sport 02's which tend to not run as wide as the mps4s so expect to have to run a degree or two more than I did.

I personally believe that this is the best setup for the f22 chassis and am going to run it again on my m240i with a 17" wheel instead.

Thanks so much! Looks like there is a slight chance to make this work, but a very long shot.

And "downside of ownership" lol - I feel that!

I might just use this set on my 1er instead and get a better spec wheel set for the 2er! Looks like staggered is the move, but i really want to do the square! I will research and plan some more.

Thank you again for the great advice and guidance.

Consider 235/40/18 or 245/40/18 if you don't mind losing a little contact patch. 245/40/18's look and drive great on my 18x8.5 ET35 FL-5's, though fitment is a bit questionable up front after lowering it. Camber's at -2.3 and fenders aren't rolled, but could definitely use it.
