I've got a GLB 250 4matic and was wondering if this size wheel would fit. I have seen some GLB 35s on here with wheels of the size and was wondering if there was something not allowing the 250 to run the same setup.
Current Setup: 235/50R19 99H 7.5x19 ET53
New Setup: 255/40R20 9.5x20 ET40

i heard if you upgrade from 19 to 20 inch wheels you will have to get summer/ winter tires

Your new set up compared to your current set up:

Here is GLB35 sizes:

I recommend to lower your wheel size to 8.5". I am using 255/40R20 8.5x20 ET42 with no problems on GLB35. Similar size 255/45R19 8.5X19 ET42 didn't fit due to AMG brakes, so I have to use 15mm spacers that I had. So it depends even on your wheel selection eg ET 42 may/may not fit. If you go ET40, you might need spacers or might be OK depending on wheel design. It will be good to try them in a local shop or order some wheel spacers in case unless sb already tried and has been using those wheels on a GLB.

No, you can have any tires you want as long as the tires/wheels meet the MB specs. MB puts summer tires on GLB35 with 255/35R21 and 255/40R20 tire/wheel combo in the factory as they don't give any A/S option to buyers. Similarly Tesla comes with 255/35R21 Michelin PS4 AS's as standard, which I used as summer replacement tires for 21" wheels on GLB35...
