Hello Guys, I purchased this GLS450 2018 Used last year. I noticed the rear original tires had almost no thread comparing to the front ones and decided to get new tries and wheels.
The wheels are AMG Replicas that I used before on another vehicle and had no problems. The tires I used are Bridgestone Dueler Alenza ( the ones that comes OEM on Suburbans and escalades )
these tires have INCREDIBLE tradewear and should last 50K+
after only 4k on these tires, i drove the vehicle this weekend ( it's my wife's car) and the car slipped / skipped seriously on rain at very low speeds ( 45, 50 ) to the point we had to get out of the highway. very scary!
I supposed the tires were still new, but for my surprise they were eaten on the inside only on the rear end. The front ones still look new. I also noticed that one side's camber looks more inclined than the other side!
My next step will be getting a new set of rear tires and have it aligned. What do you suggest? do you think my bigger wheels ( from OEM 20 to Aftermarket 22 ) could have caused the wrong camber, or does it seems like it has a suspension defect? sounds like a warranty issue?
should Mercedes do the 4 wheel alignment ( extremely overpriced ) or my tire shop can do?
Thanks for the inputs!
This side looks angled This side looks straight Front tires like new Rear tires (only 4k miles ) very wear Rear tires (only 4k miles ) very wear

Sorry to hear about the tire wear. It is a very common complaint on the GL/GLS.
Your car is an X166, correct? This has been posted in the X167 forum.
22” wheels are part of the problem. Larger diameter wheels with excessive, although OEM spec, rear camber will create more tread wear.
Assist systems like active lane keeping, basic cruse control and Distronic all use the rear brakes and contribute to rear axle tire and brake wear.
Its a crummy arrangement and in my view Mercedes has missed the boat completely on this.
