Good Afternoon all! Just purchased a 2025 GLS450, with all the nice options, and the lovely catalana interior about a week ago. So far, love the design, interior, the M256 quietness, and MPG. However; one thing I’m noticing, and noticed quickly is the rough ride. I have the 21 inch amg 5 spoke pirelli p zero all season tires on mine. However, it still seems to ride very harsh over small and big bumps for a vehicle having airmatic. I do have a 2023 EQS SUV also but it has a wonderful magic carpet ride. The previous vehicle I traded on this GLS (2024 MDX Type-S) rode better which is shocking to say. Tire PSI is 31-32. Noticed the 22 inch rim option has same sidewall ratings but with summer tires. Should I have went with those instead if they provided a smoother ride? Just confused because I have driven GLSs in the past, and they all rode very smooth. Has anyone else noticed this as well?

That's odd.
You said tire pressure is 31 - 32. How does that compare with the gas flap recommendations?
My 21 inch Conti's call for 35 - 41 and they don't feel harsh.
I normally associate lower pressures with smoother ride, but too low might reduce the springiness of the tire.
Let us know what the gas flap says.

Well I don’t see anything underneath when I looked. The vehicle I bought was a dealer trade out of state from my local dealer. (Only been on their lot for about 1-2 weeks). However, just noticed this one has a production date of 12/24. Wonder if it sitting on the lot for 6-7 Months affected the tires?

Does it have run-flats I am not sure if someone already answered?
Check tire pressure again. Make sure the tires look ok at a shop and get them balanced. Are they run flat? I would personally get rid of the tires and find a nice set of Michelin. Is the car in comfort setting? A GLS at least the ones I have been in all have a the magic carpet ride. If that doesn’t work consider a small rim and thicker tires. Large rim sizes tend to give poor ride.
The GLS will never ride better than the EQS, but should ride much better than the GLC.
Did you check the tire pressure via an actual pressure gauge? 32 PSI should be great. I like the factory tires that came with those wheels, but am gonna replace them this month with MICHELIN
PRIMACY TOUR A/S. They also come with 55,000 mile threads warranty.

Tire pressure according to app is 31-32. I will go to a shop and have them check tires and balance them to see if that’s the issue first. Cannot go wrong with Michelin. Definitely will be getting a set next. GLS always has been in Comfort/Eco.

I did not actually think of that! Will check at my local tire shop tomorrow. Yes. You’d think 32psi would be wonderful! This has airmatic so over the littlest bumps I felt it in the cabin quite a bit and was shocked. Will go Michelin next. Yes, EQS is so good when it comes to ride quality,
We’re 21’s staggered as well, but not AMG (I don’t do MB AMG, but different topic). Ours came with the Pirelli’s as well, then switched over to the Michelins at 25k ;staggered set up, rears wear twice as fast as fronts.) We’ve been happy with the Michelins ever since (90k). We replace the rears about every 25k, fronts about 45k. We too run st 31 psi.
that said, not a major difference between the Pirelli and Michelin when we made the change, in terms of ride quality. Never been bad, but the car does transmit the surface of the road a bit regardless. I will say though, I think the Michelin’s prioritize comfort over sport, and I personally think the sidewall has a little more forgiveness.
that also said, check your drive mode setting. Make sure it’s not in sport, which lowers it and firms it up a little. Leave it in comfort, or eco for less transmission shifting as well. I’m in eco 98% of the time when I’m driving it.

read the fine print on the warranty if you’re a staggered setup (wider tires in the back). Michelin knows and acknowledges the fact the rear tires wear twice as fast, and therefore that warranty is adjusted accordingly for the rear tires.

Not if you buy it from DiscountTire. The warranty goes through DiscountTire and they are backing it up based on their own fine print. You are right though if you order through other shops that will rely on the OEM warranty not their own. DiscountTire would just match the manufacturer, and you will deal directly with them for tires replacement. They will then deal with the manufacturer on their own. I’ve had a claim once for thread lifetime warranty through discount tire on a staggered setup; no issues at all through DiscountTire.
This is the same reason I just bought new set for my i7 as an EV through discount tire, cause I know that tire will only last 10K-15K miles, but they come with a 40 or 50K miles warranty as a I remember. DiscountTire has no fine print about staggered fit. I confirmed and asked the question when I got the tires.
Interesting, I’ve never heard of a tire shop overriding the warranty language of the manufacturer before! I’ll have to check them out when we’re ready to replace ours again!!

There is a new Les Schwab store in our town and I went in for a flat fix, which is free in their effort to draw customers.
I asked them about mileage limitations on staggered tires and they said they base it on individual manufacturers' limitations.
I called Costco about Michelin Cross Climate that I plan to get for my new wheels. The guy asked if the car has a spare which mine does not, and he informed me that Costco will not honor the road hazard warranty then. He said they void it due to having to drive with a flat that will ruin the tire. I get it I guess but I told him if I get a flat on highway I am not stopping on the highway to change it if I had a spare. That part doesn't make sense to me at all. Anyone ever hear this ?

what do you mean with harsh ride?
for example we have a 2024 GLS 450 with airmatic suspension + 23 in pirelli summer tires.
The only magic carpet ride we have had that idolated everything except big bumps was the Range Rover sport 2018 and land Rover discovery 2017.
I had a 2020 x6 g06 with adaptive m sport air suspension.
Very very compliant but no magic carpet.
THIS gLS is soft... yes... but you feel the vibration on the cabin and can hear it on the trim... bigger bumps are felt and heard too...
Over all is acceptable for who wants a very soft car...
but minee is extremely soft and the rear suspension skips side to side...
Carwow did a review and confirmed an unsettled ride quality on the gls.
ITS not the first time ive heard that the 21 in doesnt feel very soft..but usually is subjective...
comparing a sedan vs an suv isnt the best...
did you test drivee the gls before purchase?
the mdx type S adaptive air suspension... personally isolates the vibrations i had the opportunity to do a drive back to back... between my x6 vs the type S....
my bmw won... but it was an acceptable rival.
Interestingly... my 2019 lexus ux250h f sport... has a better ride quality than the GLS...
and my 2022 Land Cruiser Prado 150 series with kdss drives a lot better.
then again its subjective.

Yep, that makes sense to me. Snippet below is directly from the Michelin website on warranty coverage, so it's pretty impressive that Discount Tire would overrule this policy for a staggered setup car. I have little doubt that if Discount Tire were to honor a 50k mile warranty at 30k actual miles and look to Michelin to compensate them for the coverage that Michelin would deny their claim in a staggered set up car, such as the GLS with the staggered tire size option.

What is the deal with that side to side shimmy? I feel it in my 2022 with the 23" and it's strange, also saw the CarWow review that mentioned it. Is this a flaw in the suspension geometry or is it the massive 325 width tires tramlining?

It's tramlining. I get it on my GLE with the same width tires on 22" wheels. When I switch to my winter wheels running 275/50R20 on all corners, the tramlining disappears. I rented a GLS with 21" wheels two summers ago and did not get any tramlining.
I was curious about this, as we're probably 10k from needing new rears again. I can confirm on the 21' staggered setup, Discount Tire will not honor the 55k mile warranty on the Michelin Primacy tires due to the staggered setup. When you buy a "certificate" from Discount Tire (basically like those protection plans for when you buy a new gadget), if there is something defective with the tire itself, they will replace it for the cost you paid for the tire. This protects you from price inflation. However, if I were to come into Discount Tire at 27,500 miles with 2/32 tread depth on the rear tires and tried to activate my previously purchased Discount Tire Certificate that I paid extra for when I bought the tires, Discount Tire will deny the claim, citing the rear tires performed to manufacture specifications via their language for 50% tread life on staggered setups.
SW222, you may have a unique shop you're dealing with, or they didn't quite understand their program when they sold you the tires, but according to Corporate, no Discount Tire warranty overrules the manufacture's stated coverage / limitations. I'm bummed by this, as I was hopeful that you unlocked a new level of unicorn for the universe!! If it's working for you though, then you're lucky and should buy that shop you deal with some free pizza and beer!!
