Hey guys -

Does anybody know if an 11" width rim with offset ET18 will fit 2021 M550?

Right now my 668m rear wheels have a offset of 44 and I'm using 20 mm spacers.

Thanks!

I doubt that et will work. You'll probably be sticking out of the wheel by like 3/4".

Now, an et 40 would stick out the same amount as what you have and may just squeak in there on the inside clearance.

Thank you. Makes sense.

Their website shows a sizing table with a 44 mm offset as well. But I don't see it in there drop down selection. I'll call them tomorrow and see if they still make the 44 offset.

Question.. would a 10" wide rim with a 22 offset look the same as 11 in rim with a 44 offset? I'm speaking in terms of the face and the lip. Thank you.

I should clarify on the previous comment. The tire will stick out the same amount with an et40, assuming you're running 275/30r20 and will be running a 295/30r20. The rim will stick out about a third of an inch.

In your second scenario, you'd have about 5mm less poke than the 11x20 et44, and way more suspension clearance.

Here are a couple of great sites to compare wheel and tires sizes/offsets.

Thank you for the links. I was watching some YouTube videos and I was starting to get it, but it was still a bit slow for me to fully grasp.
