GLC43 Rim size and offset?
Can anyone tell me the OEM rim sizes and offset? Also any good rim recommendations?
Looks good! Have you tried lowering the rear air suspension with the button/switch in the back? Would you mind doing that and taking a pic inside the fender?
Curious what the clearance is like.
I wish there was more info on this too....it seems hardly anyone has changed the wheels on these. The few that I've seen weren't done well. (IE sticking out too far and or even narrower than stock sizes)

The official package comes with 4 19 inch wheels. Does anybody know what offset/width they are?
Ideally I want wheels that are sticking out as much as the summer wheels that came with the car.

it is too early for winter tires or should I say to late LOL
19 stock size
F- 235/55-19 8Jx19 ET38
R- 255/50-19 9Jx19 ET20
Hope this help
The size you gave me are the official rim size with summer tires right?
I was wondering what size/offset were the 19 wheels that I linked for the winter tires configuration that MB sells here. They all seem to be 235/55R19.
I’m new to the forum and the GLC43. I got an aftermarket set of square setup wheels for the winter and the rear wheel looks too tucked in. I’ve been looking for compatible spacer, but there isn’t much info. I even called H&R and they can’t guarantee the fitment because all they list is the 300 model. You are one of the first folks I see running spacers. Can you please share what you successfully installed?
I’m looking for 20rear and 5 mm front. The new 19” winter wheels are ET38. The front one is slightly rubbing against the caliper and the back one fits but it is too tucked in.
Any guidance is greatly appreciated.
Thank you

Those spacers seem to work.
If you go to the ECS tuning website you can find the HR DR Trak Spacers that are 5mm, 15 and 20.
Also you will need longer bolts as discussed in that thread. I believe stock bolts are 45 mm long so add the spacer thickness you want to that.
So 45mm + 5mm spacers you would need 50 mm long bolts.

FYI I don't know if it's true but I was told that the specs for the GLC 300 are the same as the 43 and that 13mm is the minimum that you can use.
