Upgrading from 20" to 21" inch Wheels - Advice Please?
My thinking is this will work great as I'll use the 20" wheels in Winter/Fall and the new 21" for Summer/Spring. I believe I found the exact wheels I'm looking for (or very very close)- link below.
- I found these via a aftermarket shop that I've heard good things about. I have two friends who both used them (one with a Mercedes and one with Range Rover) and they were very pleased with the result.

Looking for any advice from folks who have successfully done a wheel upgrade like this? Thanks in advance!
Did a quick and dirty mock up to show the change in look (rear wheel is the 21" front is the old 20").

I tend to agree with Hutch that finding some OEM takeoffs would be better - shouldn't be too hard (like this good deal with tires and sensors: https://mbworld.org/forums/market/770937).
Also, add your location to your profile.

My 450 wasn't AMG package and I had that problem when I ordered my aftermarket wheels. But I already had planned on adding the AMG styling so at the end it worked out.
I have noticed that my car with the current 20" does seem to have the more flared black plastic on Fenders...I'll take a picture of my GLE later today.
On the MB website I see that if I configure a GLE with the 20" non AMG:
Then if I swap to the NON AMG 21"
--the black fender plastic is alot wider. This is how my GLE looks- the black stick out a good bit for sure.
I added my location...I'm outside Philadelphia but also in NYC area a lot. As for the deal you posted...are they exactly the same fit 2020 vs 2022?

If your GLE looks like the bottom pic with the larger wheel flares, then you are sorted. 21"s will fit just fine.
Here's my wife's non-AMG GLE with 21"s (275/45 fronts and 315/40 rears). Front flares are also slightly larger than base model:

@gregw - Can you share where you pulled the wheel specs from...I wanted to check the difference between the 21" non-amgs (like in images above) vs the 21" multi spoke amg...I think the amg wheel may be a hair wider but could be wrong.
@EddieKBG - I'm going to check with my dealer what the AMG front end would run. That is the one piece I'd like to swap in. Thanks for the info!

If you manage to pull your rims out can you right down the part numbers of the rims please (front and back).

When I traded in my SL550 and bought my SL55 AMG those wheels (20-inch with staggered Continental Extreme Contact Sport Plus) had 4000 miles on them since new, so I kept those wheels and had the selling dealership transfer the wheels.
They used rusty lug bolts from the SL55 to put on my nice new wheels. Looked awful, besides I didn't know if the lug bolts were the right length, also the bolt to wheel interface can have different shapes: cone, ball, taper, etc.
So I called Tire Rack, told them what the dealer monkeys had done, and they knew what exact lug bolts had come with my wheels. Sent me a new set for only $30 instead of $8 each!
My GL450 SUV is wearing XIX X15 22-inch wheels with Lexani tires.

Here are pictures of my car (non-AMG style GLE450), where I swapped from the standard 20s to 21s. I bought the replacement 21" rims from eBay, from another GLE owner, and added the tires/TPMS from Tirerack. The tires are Yokohama GeoLandar X-CV in the factory staggered 21" sizes.
I believe my fender flares are the more flared variety, which gives the new 21s a tucked-in look.

I have been looking for them. Im tempted to buy some Niche wheels 20x10.5 all around.
