Use GLA250 winter wheel/tire on GLB?
I have a Tire Rack winter set I was given by a family member, only 1K miles on it, so I’d really like to make it work. From what I can tell from reading, it looks like I just need a 10mm spacer to make this 18x8 offset 35 wheel fit, or can I get away without the wheel spacer? I know tire size isn’t stock, but it’s a small enough difference for my predominantly around town usage that I don’t care about the speedo error or clearance change (coming from a Sonata N line I’m way in the green in the clearance column).
Thinking about These wheel spacers
Here’s specs on package, assume hub dia. and TPMS specs are same, but correct me if I’m wrong please.
18X8 5-112 ET35
A1028802GB GLOSS BLACK
SE A10-2{} 72.2MM
72.2-66.6 CENTER RING

My GLB35 is fine with 20x8.5 winter wheels with ET42's. I don't know if GLB250 and GLB35 has the same fender spacing, eg my MB wheels are wider 255/35R21 ET51, but your set up shows 0.7 mm more on the outside compared to mine which should be OK. Your new tire ET is pushing more to outside, so you don't need any spacers. Since you have the tires, you can install and check it if it clears the fender.

Compared to GLB250 set up your wheel size is going down 3.39% (2.86% compared to GLB35). They usually recommend staying below 3%. Also you are loosing nearly half an inch clearance. Lowering the clearance might not be good for snow and water puddles in winter depending on where you live... Again it is your choice...

I am jealous of your 35, I have seriously considered trading up to that, I thought I could live with the drop in performance, but man, it is such a huge drop. The midrange passing of my N line was better than even the 35, so the stock 250 is killing me, slowly.
