I think I’m just gonna avoid it with the all terrain for now nervous about bending one of these nice rims. I got the non staggered to be able to rotate them.
Ka-thump, ka-thump, ka-thump (repeat a thousand times) - that's so true about driving over the Mount Hope Bridge!

Even areas around southwest Florida the roads are getting really worn out and rough. Rhode Island has always been bad. The other day I was only going 30 mph and I still bottomed out over the last set of bumps. It’s ridiculous all I can think of is the state is trying to deter people from going over the bridge to save on wear and tear to prolong having to build a new bridge. The bridge was built in 1933. I just wish so many modern cars didn’t use such low profile tires. If the car used 17s with higher profile tires it would save people a lot of aggravation in replacing damaged tires and rims. Would not look as good but would be a lot more functional
The roads all across the country are in bad shape. In TN they are pretty bad with lots of huge potholes that look like they can swallow a small car. Most roads are just riddled with crappy patch jobs. When they do rip up the pavement and lay down a fresh layer of nice smooth pavement, it lasts about a year and it starts to deteriorate. I think there is just too much traffic and too many heavy vehicles driving on them. I took a ride to Detroit today and roads are even worse which was expected. Much worse than TN, particularly on the interstate.
I haven't seen any potholes in my area, Clearwater, Florida. Our city is proactive when it comes to street repairs. Of course, we benefit from stable temperatures all year. IMO it is the freeze/thaw cycle that kills roads.

If in the salt belt, salt makes it worse, it creates a void.
Proactive my area of MS - Interstate, state highways and county roads are always in top smooth shape versus Louisiana
You can tell where state line is just by the quality of road.
Around here they add lanes before they are needed and bridge repairs etc.
I guess it is all that Casino Money from the Gulf Coast helping as most roads that lead to HWY 90 on Coast tend to be very nice.
State made interstate 3 lanes before it really needed by years and are continuing on that project so I-10 will eventually be 3 lanes from Louisiana to Alabama.
Just to be safe today I brought the pressure up to 37.5. A little less likely to damage a rim. Too little tire pressure can bottom out the tire with the rim on a sharp pothole and rim damage is more likely to these 20 inch rims sure are at risk with the low profile tires. If I’d thought about it more I woulda went with the 19 inch rims sure are option which I believe was base for these cars. Not crazy about the way the base ones look though.
As Rowersaay posts in #19 above the 2024 GLE has 4 identical wheels and tires, except for the different offsets of the front versus the rear, and this make tire rotation impossible, short of flipping tires. I would investigate either machining down the hub of the two wheels with the greater offset (the two that sit the most outboard) and then compensate for the difference with wheel spacers. All 4 wheel offsets would then be identical and the tires could be rotated.
I think this would be a bad idea. First, removing any material from the wheels with higher offset would increase the difference between the wheels. Second, the lug bolts might be too long if material is removed from the wheel. Finally, altering the actual offset without changing the ET designation on the wheel is likely to confuse people.

My proposal is predicated on the assumption that all 4 wheels are identical except for the thickness of the hub that accounts for the offset difference. Machining the 2 thicker hubs to match the dimension of the 2 thinner hubs makes all 4 wheels identical. (Alternately, purchase 2 more of the OE wheels with the thinner hubs.) Then compensate for the difference with spacers in the 2 locations to achieve the original offset. The lug bolts for the thicker hubs should already be longer, and fit the now thinner hub plus spacer just as with the original thicker hub.
Crazy? No more so than the MB engineer who signed off on equipping the vehicle with Franken-wheels. And no crazier than all the owners who install suspension lifts, carve away wheel-well liners, relocate oil coolers/plumbing and install wheel spacers with longer lug bolts all toward achieving that "aggressive" look with bigger tires that they can't even see from the driver's seat.

Correct, 18" 5 spoke are standard for the W214. I'm not a fan of the wheel design myself. That's more why I got the 20" even though I planned on getting custom wheels.
Maybe for the sedan. The wagon wheels are slightly larger/wider and begins at 19", as far as I know. For instance, the widest tires that come on the Sedan are 245/275mm front/rear, while the wagons come with 255/285mm front/rear tires.

That's how mine came. The 19's are a nice compromise. A bit better ride than the 20's, looking better than the 18's.

The European All-Terrain, gets optional 19s, with the staggered 255/285 wider tires, in addition to the 20s with the 255/285 tires. I like the wider tires, but prefer if they came with 19s than the 20s, but of course in the US, we only get the 20s with the wider/staggered tires.

I replaced my standard/square 19s, with the staggered 20s with the 255/285 tires. I don’t find any difference in the ride quality, between the two sets.
I would not go below 36 psi cold. 32 psi seems underinflated to me.
Either way, the conditions you describe, sound awfully brutal to the suspension of any car. More off-roady than on-roady.
Remember, the tire air pressures do tho things. First to carry the static and likely dynamic load and Second, along with the tire construction, the handling characteristics of the vehicle. So, consider using the vehicle placard pressure and not adjust for ride compliance.

I agree. The tire pressure details seem to be present within the Gas-tank filler cap, when you pop it open. It shows the pressures needed during normal load, pressures under maximum load conditions and also a +2psi when driven over a 100mph.

The tire pressure on the gas cap, not the ones on the door jam should be used.
For my E450 under normal driving conditions it is 32 psi, front and rear. I keep my at 35 psi all around. (10% more) I find the handling is a bit sharper, tire wear and mpg a bit better, ride no different than at 32 psi, an excellent compromise. The 35 psi is cold, after standing in my garage overnight. I do it first thing in the morning before driving.
On a lighter note, my 20" Mercedes staggered wheels/tires (factory upgrade combination) arrived today, and now they are on the All-Terrain. To me, they look pretty cool.
20x9 ET32 front, with 255/40ZR20 tires
20x10 ET48.1 rear with 285/35ZR20 tires
I expected the combo to ride a bit firmer than the stock 19" with the 19x8.5 square wheels with 255/45/19 tires, but no, the ride is as compliant as the original combo, and the steering feels sharper and more responsive.
The tires that came on the stock 19" combination was All-Season, while these are Pirelli Mercedes-OEM-Spec Max Performance Summer tires, and I will change them to my standard Michelin Pilot Sport A/S 4, once the summer wraps up.
After some hemming and hawing, I switched to my regular favorite Michelin Pilot Sport A/S 4 (Ultra-high performance All-Season category) tires, right away, rather than waiting till the end of the summer season.
I went slightly wider in the rear……. instead of the standard wagon size of 285/35/20, I went with 295/35/20. I kept the fronts the standard size of 255/40/20.
The front set (255/40/20) is 28” tall, while the factory sized rears (285/35/20) were 27.9” tall. My rear set (295/35/20) is 28.1” tall.
I was debating putting 265/40/20 in the front and 305/35/20 in the rear, and in the wagon (which does not have the rear wheel steering of the sedan, and thus has a lot of room), there’s more than enough space for this combo, with no spacers or other complexity, but I decided to go conservative and stick to a size close to the factory size. This 265/305 combo would have added an additional 0.4” to the tire height (front and rear), and resulted in a bit of speedometer difference, but of course since I did not go for it, the point is moot.
At the recommended 36PSI tire pressures, front/rear, I felt the ride to be too soft, even in Sport mode. I switched to 40 all around (which is recommended by Mercedes for a full load and at higher speeds), and the ride is taut/firm, and perfectly aligned to my preference. Love this new setup, and the rear has a solidly planted look and feel. I went on my regular mountainous road with a lot of curves and twists, and the car hangs onto sharp curves like there’s no tomorrow, despite speeds that were significantly higher than the posted limit.
