You're limited by your rear tire selection, and a 20x10" fits any tire you could want to run in the rear if you plan to stay within the maximum tire widths recommended for an F10.

If you have a serious need to add rear traction, a different selection of tires, or a wider tire can help, but on this platform, adding a massive rear tire and a massive rear wheel does nothing but hurt the overall feel of the car with an unnecessary stagger and added rotational weight.

Again, it depends on the overall goal you're going for, but to increase the wheel size, and still keep the car feeling quick on it's feet and increase the vehicles responsiveness and overall dynamics, go for a light wheel in a 20x9" & 20x10" set-up. That's what we run on F10's, and have had nothing but great feedback so far. A 20x10.5" is fine in the rear too.

Hope this helps!

Here's one of our 20x9" & 20x10" set-ups on an F10, running a 285/30/20 out back:

This is what one of my quotes recommended:

TOYO PROXES SPORT
Ultra High Performance Summer
245/35R20
275/30R20

I'm in the exact same situation and am two weeks out of delivery of my F14s.

I'm running 20x9 ET+35 front's with 10mm spacers so ET+25 on 255/35/20 and 10.5 ET+40 rear's on 285/30/20 NITTO INVO tires, 2013 535i Xdrive M sport lowered on H&R sport springs, no rubbing at all with 5 people in, it actually drives awesome.

I am always so lost on the spacing vs all other spacing.

I just bought myself a 535i 2013 and want to go with the biggest tires I can go with on my car. The picture below with Size: 20×9.5 | 20×10.5 is exactly what i want but the rim size does not specify what the offset should be. I don't really understand what the offset means either

I can buy them from here

20x10.5 Blank (Custom Drilled BP) Gloss Black 30MM

20x9.5 Blank (Custom Drilled BP) Gloss Black 30MM

Is the 30mm spacing fine for my car? is the difference notable say if I got 35mm spacing? Thanksa to anyone who probably has answered this question a 1000 times

30 is not enough on the back, you'll want 40 for a 285 tire and min 45 for a 295 tire in my opinion. This is based on what others here are using. Some claim success with more aggressive fitment, but that's starting to cut it real close.

Thanks for the reply. Can I just buy a 10mm spacer for my back and that fixes the issue. I am very clueless about spacers and the whole offset thing. Thanks again for the help

No, spacers make it worse. Makes the offset lower, in this case putting a 10mm spacer on a wheel with an offset of 30 makes is 20.

Thanks again for the help so for my back i want to go 20x10.5 @40mm and the front would be the 30mm be fine?

Those offsets should work but may depend on your tire choice. A 295 will be tight on a 40 offset, so if you can't get 45 you may need to stay with a 285.

Once again, many claim they can go more aggressive but I would err on the side of caution unless you want to tinker to get the fit just right. This could include changing tire/wheel sizes/offsets and playing with alignment settings, and will depend on whether you are lowering the car or not.

If you are not lowering the car, more aggressive fitments can stick out or "poke" which looks bad, in my opinion. The tires move inwards as the suspension compresses, so a lower car will support a more aggressive fitment than one that sits at stock ride height.

Your best bet would be to do some research; look at a lot of pictures and ask lots of questions about the wheels you're buying. Be comfortable with the purchase ahead of time. Good luck!
