GLE 43 Coupe 22" Tire Options

I'd think that they use both tires at the factory, depending on what they have at the time. I've heard that things like tires are multi-sourced based on availability and price at any given time, so it could be either one on any given day...

I'm assuming that you left the wide rims on the back and the narrow rims on the front, or did you change all four positions to the narrower front rim???

Hummm...
I just found this link on TireRack:

It says this:

It says this:
Because tires have flexible sidewalls, a single tire size will fit on a variety of rim widths. A tire's rim width range identifies the narrowest to the widest rim widths upon which the tire is designed to be mounted during its tens-of-thousands of miles and years of service.
The width of the rim will influence the width of the tire. A tire mounted on a narrow rim would be "narrower" than if the same size tire was mounted on a wide rim.
Note: Because the overall diameter of a steel-belted radial is essentially determined by the steel belts, there is little, if any, change to the overall diameter of the tire due to differences in rim width.
The industry rule of thumb is that for every 1/2" change in rim width, the tire's section width will correspondingly change by approximately 2/10".
IF you did put the smaller tires on all the way around, according this webpage, you would not be changing the overall diameter of the tire. That's encouraging, and that may be something that I try next time as well. It would mess with the "look" a little bit, but I don't know how many people, other than me, actually notice things like the fact that the rears are wider than the fronts.
Aren't the stock rims 9" for the front and 10" for the back? If that's the case, the tires would only be 4/10" narrower than the stock setup on the rear tires. I have measured them, and the fronts are 10" on the ground and the rears are 11" on the ground. That would make the rear tires still wider than the fronts, but only 10.6" on the ground.
Interesting to see how this works out...

I need to correct my last post, as I misspoke. There are NO winter tires in that size, my apologies.
Just for the record, these are the tires that are available in the 285/40/22 size: (3 AS and 4 summers)

Very helpful, thanks for including the screen shots! Those may create some options if I could get away with running AS tires in the winter.
Another issue I am not sure about is what the 285 tire would look like like on the 22X11.5 inch rim. It probably won't look stretched, but the tire might look a lot narrower on the back of the car compared to the 325s.
I have the Conti-CrossContact LX in the 21", they are a bit noisy.

Oh shoot in the Contis. I just put the 22" version on my GLE43. I hope they are not noisy. They haven't been so far, but we only have a 1000 miles so far...

The tire calculator says 305/40s are only 1.9% larger than 285/40 (and 325/35), which should actually (within 3%).
The website for DIscount Tires stores in my area has a number of tire options for 305/40 22s.
So 305s may be an option, this might work better than 285?.

There would at least be some visible offset with that setup...
#38
Do you think there is enough clearance to run 305/40 all round (fronts too)?
This would lose the stagger, but no issues with a difference of the rear wheels having more 2% circumference than the fronts ?

285/40R22 on all four corners should work.
Diameter should remain the same at 31.0" and most 285/40R22 can be mounted on 9.5-11" rims.

...and there are all season options in that size as well!!
I'll keep this in mind for the next set.
On a tire related side note: When the rear Pirelli stock tires on our '17 GLE43 Coupe only lasted 10K miles, I decided to try the only brand in town, the Conti's. They seem to be holding up better than the Pirellis, but it's probably a little bit too early to tell. I'd still be surprised if we get 15K out of them...

Hey guys. I've been battling this problem with my 22" wheels for the past 6 months. I didn't want to pay $5000 or so for new wheels, which are the cheapest available for the 63S, but there are more wheels compatible and approved by MB for the winter.
Look at the MB After Sales Portal for the compatible wheels MB offers along with the tire sizes that fit. https://asp.mercedes-amg.com/certdocs
I had 22" and had to get 21" so I can have All Season and Winter Tires as needed. I just don't have space for my 22" wheels now.

I am thinking of going with 305/40/22 all around with Yokohama Parada Spec-X all season tire unless it is going to cause rub in the front, then next choice will be 285/40/22.

I don't think that anyone has responded to any of the post that have questions about the tire sizes all being the same size. I need to change all of my tires soon, and I think I'm going the all 285 route. I would still like to know if someone has done that, and what hapoehap, if anything...

Quick follow up on my tire journey...
I decided to purchase 285's all the way around, mainly because I wanted to get rid of the summer tires, and go to A/S (all season) tires. We were only getting 10K miles on the rears, the original Pirellis, and the Conti's, which I thought would be better, but were ultimately the same.
So, I was on the hunt for a 285 A/S tire, which is the front tire size, and I decided on Parada Spec X's, and I put them on all four corners. I'll try and get a picture of what it looks like, but it does not look as good as the 325's on the rear, I will say that up front.
The other issue that I had was that my local dealer would NOT install the 285's on the back, because they were NOT the factory tire. I decided to not even argue with about the tire diameter, and the fact that the tire would fit on the rims, yada, yada, yada. I had them installed at a local dealer. He did not stock the tire, so I had to order them off the internet, and they gladly installed them.
But, here's the unexpected results from this:
All-in-all, I'm actually happy with the switch so far, and again the only down side, is that it doesn't look as good from the back, with the narrower tires, but if these tires last even twice as long as the summer tires, it's a win, and now at least I have tires that are at least somewhat "winter" capable. Fortunately, we never really had any snow since we've had the Coupe, so we never had to try driving with the summer tires...

But, here's the unexpected results from this:
- No more issues being thrown around. If you look back at this thread that I started, I was having issues with our Coupe being thrown around on the road from our house into town. At times, it was actually almost unnerving what it was doing. After installing the 285's all the way around, this has almost completely gone away. The only thing that I can figure is that extra 40mm tire width on the back was actually much wider than the ruts in the road, and that was what was throwing us around. It obviously didn't have anything to do with the stagger, which is what I suspected the issue was
- Much smoother ride. It's either the tires that I installed, or there is just something inherently better with A/S tires, but the Coupe actually rides much smoother now, than it did with the summer tires. I would have actually thought the exact opposite, though, as the summer tires were much softer. I would have thought that they would have ridden much smoother. They absolutely do not.
- Much quieter ride. I guess that I never really realized it, but the cabin noise with the summer tires was much more than it is with the A/S tires. Again, maybe that's the design of the tread of one vs. the other, but it is definitely quieter now that it was with the summer tires
All-in-all, I'm actually happy with the switch so far, and again the only down side, is that it doesn't look as good from the back, with the narrower tires, but if these tires last even twice as long as the summer tires, it's a win, and now at least I have tires that are at least somewhat "winter" capable.

I did the exaxt change for my car three weeks ago. So far so good, like the Yokohama tire. Agree with the downside look of the narrower tires in the back but that is something will get use to with time. I am happy that I can drive the car all year long now.

Thank you for the update. I do some occasional commuting between cities and was looking to the Parada Specs myself.
Really interested in the pictures when you get a chance.

Pics of 285's on the rear...
I don't know if any of these pics do this any justice, but here they are. Please disregard the looks of our Coupe. It's a mess right now...
