The 9x20 ET28 wheels will fit just fine at all four corners though and at least a couple of people have done that (all 4 wheels identical) so that you can "rotate" between front and rear each season to help balance out wear.

Thank you for the reassuring reply! 🙂

I think though the winter OEM 764M rear wheels are 9,5x20 ET39. 9x20 ET28 is only poking out 4,7mm than this wheel and 1,7mm less than the 21" OEM 892M wheels. So I really cannot see any problem with it. The advantages of a square setup for winter are obvious to balance out wear 😉

Hey all.

Just wanting to ask a quick question about the setup I'm looking at to see if you all think it will fit with no issues.

MSW type 74:
19x8.5 +35 w/ 255 45r20 Scorpion winter
20x9.5 +35 w/ 265 45r20 Scorpion winter

Thanks for any help you can provide!

255/45R20 square is the proper winter setup, don't go wider if you live anywhere that gets consistent snow/ice.

I find the 255 too wide still, and I find they slide too much compared to the 225s I had on my 340i I just got rid of, but those were also much better tires (Hakkapeliitta R5) compared to the Scorpions. When I have to replace them I'll probably go with 245/45R20 Hakkapeliitta R5 SUV.

You should be fine!

I know the old school of thought was the skinnier the better in the snow and ice but I've had some pretty wide rear tires on my Cayenne Turbo, CLS550 and now my X4mComp and have run square set ups as well. I have had zero problems and they feel like they brake better.

The biggest issue I've had w the X4M is it absolutely burns through the rears with the rear traction bias. Here in Minnesota, the roads are cleared of the snow quickly and regularly, the soft winters just get eaten up by the bare pavement in between storms.

On a side note I went with Michelin Cross Climate 2's All Weather and have seen zero drop off in traction in deep snow on ski trips.

Best!

Here a nice write up on width:
