2018 GLS-550 Tire Wear
#26
I currently have 2017 GLS550 with 11,400 miles on it. It still runs on the original set of Continental CrossContact UHP (Ultra High Performance) tires which I really don't like. Roads and highways in Sothern California are pretty rough and have grooves cut through the concrete surface to help with water drainage. This, in return, introduces more noice and with UHP tires the car experiences vibration since the tires seem to be tracking the groves in the road's surface. I bet that Germans never thought of such peculiar things as groves in the roads' surface when designing these cars for autobahn.
I am looking to replace the original set and currently considering ether Continental DSW06 PLUS or Michelin Pilot Sport All Season 4. Both of these models have 45-50k thread warranty and priced similarly. Does anyone have experience with these tires to provide a recommendation which set would be a better choice for GLS550?

We're about to need new tires on our 550, it has the CrossContact UHP's on it right now. What would you guys recommend for a tire where the car will most likely never be driven in snow and maybe drive in the rain 3-4 times a year? (Phoenix)

this is what the right rear looked like yesterday. I checked the toe myself, it had less than 1/8” toe in on that axle. I guess it must be the camber? Installed new Michelin Pilot Sport All Season’s today, but I’m planning on taking it to a shop to get it looked at. That kind of wear for no obvious reason is beyond ridiculous.

It's the factory camber specification. It's too much. The camber setting is chosen so that a GVW-loaded vehicle maintains yaw stability during an abrupt high vehicle speed lane change. Sounds like a good idea but the practical implementation means the GL/GLS is a tire gobbler.

Unknown, we bought the car a year ago with these tires on it. The fronts looked great, probably could have gotten another 15k out of them. We don't drive the car much aside from one 12 hour trip to Park City last fall, but the rest of the time it's to the grocery store and to pick up our son from daycare 2 miles away.

I bought my 17 GLS550 expecting to replace tires every 20k miles. I did the research. It is what it is. This is a high performance 7 passenger heavy SUV with dynamic driving capabilities close to a sports sedan. Tires won’t last on it like a GLS450 or a Lexus LX but neither drives like a 550. It’s a trade off. The 550 is not made for grocery getting mall cruising. That would be more so the GLS450. The 550 is more designed for performance driving as evident by the larger brakes and sport tuned suspension.

Before blaming Mercedes, I would start with a clean slate by ordering brand new tires (preferably with a mileage warranty), and take it to a MB dealer for mounting, road force balance and alignment.

You aren’t the original owner of those tires and you bought the vehicle used? Could be anything (faulty tires, bad alignment from shop from previous owner, bad wheel balance, under/over inflation etc.)

I’ll be taking to a shop where they can get rid of as much camber as possible, and I’ll have them check out the bushings back there to see if deflection is happening under acceleration or something along those lines. I know the Conti UHP’s are crap, but this is another level.

Alignment is within “spec”. And the car only has 34k miles on it. Already bought and installed Pilot Sport All Season 4’s.

REALITY IS OEM THERE IS NO FRONT CAMBER OR CASTER TO ADJUST TIRE CONTACT ANGLES !
Above is essential to spread load more evenly. All to do with cost cutting and ever increasing speed of Auto assembly lines.
For the rear there is Camber adjustment, but insufficient. We saw the need therefore to provide a Front Camber and Caster kit. Along with a rear Camber (and extra Toe) kit which allows to double the rear adjustment range.
Front kit #504016M $595 (Lowered Suspension #504016-1N $695)
(also same time replaces the 4 Front highest wearing bushings which OEM are expensive to replace).
Rear Kit #504026K $480

You may also have a bent wheel - Mercedes wheels are very strong, but I have bent two popping over a curb at around 30mph. I found a place that could straighten them and was very pleased.
I have a 2017 GLS450 - Installed Continental LX25's (275/55r19) at ~186000 back in 8-30-2021 - currently, I noticed the "S" of the "DWS" indicator worn off. I have about 256000 now. I will be reordering a new set of these tires soon. These tires also have alignment indicators when new.
I drive about 100000 miles a year (Highway and City) I have been keeping them inflated to 32PSI front and 34PSI rear (cold). Check the tire pressure sticker on the Gas fill Lid.
I also have the LX25 my 2007 GL450 (265/60r18) We don't drive this one that much anymore. It has 325000 miles on it.
I have also had a 2012 GL350 and a 2014 GL350. Both of these got up to 267000 and 263000 respectively. They had 21inch and 20inch wheels.

So far, we are loving the Michelins. My wife who drives the car mostly is by no means a "car person" but she commented to me that the car feels so smooth now. I completely agree that the tires really have made the ride even nicer than it already was. More stable, less tram-lining, nicer over sharp bumps, all of the above. Very happy with them. The wheel is not bent, they had inspected them during the tire change.

Here comes the Michelin Man

These were installed at 2yrs. The OEM Continentals failed State inspection because of sidewall cracks, terrible road noise, and shaking like crazy at speed.
I had to order from Tire Rack because the dealer refused to install them because they weren't OEM 👎

DO KEEP IN MIND NO MATTER WHAT THE TIRE BRAND - TODAYS MODELS THERE IS NO WHEEL ALIGNMENT CAPABILITY.
“FULL ALIGNMENT” IS ONLY BASIC TOE “DIRECTIONAL ADJUSTMENT”.
No longer Front or Rear Camber to adjust tire contact angles, spread load more evenly to resolve costly, premature wear. Excess edge load can also cause ruptured side walls.
FACTORY CAMBER IS SET FOR “SHOWROOM HEIGHT” CONDITIONS - no adjustment for varying height / load conditions or drivers and passengers side uneven wear encountered in day to day commuting.
Dealers only alternative (to try and placate / appease owners) stating “IS WITHIN FACTORY SPECS” (meaning at showroom height and conditions) !
ALSO SEE ABOVE #10 - ALL GLE W166, GLS W166X MODELS

Rear camber is easily adjustable. Loosen a bolt on the upper end of the knuckle and pull the top of the knuckle all the way out towards you and voila - way, way less camber and no more odd tirewear for 15k miles now. Tires are wearing perfectly. Front isn't adjustable, but they're wearing evenly as well.
