Not sure what you are talking about with rubbing but it is quite normal for the 63's to go through rear tires every 10k or less if you drive aggressively.

Ya I don’t quite understand either. No rear steer on the GLS63. Plus those are the 22’s, you can option 23’s, the sidewall drops to 35 but are still .31 inches taller than the 22’s. If it was a differential problem, like it being locked, the tires would literally drag and skip when turning, it would be very jarring. Also the GLS63 has airmatic and active anti roll bars, faults with them would have the tires rubbing the wheel well? The wells would wear out and be very noticeable before the tires had any sign of issues. An odd one that’s for sure! It’s most likely the GLS is chewing tires as expected, and the rubbing is something unrelated. Can’t wait to hear the answer/fix!
Update : post rebuild / repair / install new real differential

Thanks picked up her car the afternoon.
Shop foreman discovered rubbing noise only happened when car was cold/ not hot after running.
Forman said caused by rear differential malfunctioning and found gear oil silvery/dark. Not okay. They put in a new rear differential and rebuilt it all. Also Mercedes replaced both rear tires given the situation.
Drive- the car drives tight now and feels different. when checking out today with (service department) stated he worked 20 years at a Tires store and he never heard of a car going through tires at 6-7k miles. Obviously we know why now.
sales guy who was helping get the car repaired thinks:
issues caused by: Internal component was possibly compromised at production like the metal had some inferior qualities and with the gears running together one wore down and those shavings spread..
Let’s hope this resolves it. (See photo) Gear oil silvery/dark and burning smell - not okay
7k seems a little soon but im looking at a 2024/2025 and my research shows they go through tires pretty fast if you drive aggressively a lot
Let me know what you find out if you dont mind.
