Hi Everyon

I just brought a 2007 BMW 530i.I'm going to put some m5 166 rims, Two front tires are size 255/40/19, and two in the back are size 285/35/19, Do i need any spacer?? Please let me know. So i can put it on this Sunday.

Thanks again and have a nice day!!!

 

Hi and welcome to the forum. I've been looking for a good used set of OEM 166s and from what I recall, spacers are recommended. Do you know which offset you have? I think those come in a M6 offset as well, as style 166 wheels are offered as an option for the M6. I could be mistaken though I'm sure the well informed will chime in soon.

 

With OEM M5 166, spacers are not necessary though the stance will look a lot better with it.

The fronts are running a little wider than what's recommended (245/35) but will fit. I think the back tires are just right however, the recommended size is 275/30. I believe the tire sizes might be a bit too tall.

As far as spacers go, it's not necessary but would look more aggressive. If you do decide to use spacers, go with 15mm in rear to get flush with the fenders or, 12mm (like me) to be a little "tucked." Keep in mind my rear tires are only 275. Your 285 will definitely be closer to the fender so 12mm might do the trick.

BTW you joined in 2008 and only now is your first post?! wow Very belated Welcome!

 

You're right. They come in two different offsets, one for the M5 and the other for the M6. With the M5 offset the rears are set further in the wheelwell than the M6. The M6 almost sit flush to the fenders. The front wheels are identical on both. If you dont want to deal with spacers than M6 offsets are the ones you want.
