I need your help. Where do I start to look for the problem? I was changing head light bulbs earlier. When i turned my wheel to the inside, I noticed the entire inside track of my tire, at least an inch has worn away! I’ve noticed a slight pull to the right while driving at higher speeds but did not know this was happening. I took it to tire shop to see how long I’ve had it on there, its gotten 34,000 miles and who knows when this started tk happen.. any help would be great. Thanks.
are you running the standard wheels and tyres for your car and the suspension its at its standard ride height ?
if you have the wrong wheels and or fiddled with the suspension height - I'm not surprised you have issues - but that is so far off the edge I wonder if its hitting a suspension arm or ARB when on steering lock
heavy wear on the edge can be suspension geometry out of sorts - like too much camber or toe - but to break up so far off the side seems strange for that

what tyre pressures are you running?[/QUOTE
i am running standard wheels and tires. Suspension height hasn’t been adjusted. Car is stock.
im taking it in to my mechanic on Friday, he says it could be multiple things and obviously would have to take a look at it to get a better idea..
i was just checking here if anyone else may have experienced something like this before.

My 2010 CL550 4matic has this issue too, Front passenger. Very annoying, this tire definitely had some meat left. Still trying to get to the bottom of it🤷🏻♂️

I would check the camber. They sell a lot on eBay for our cars if you lower it. eBay item# 294449321081 is for the rear and eBay item #115362560365 Is for the front. You need 2 of these bolts for the front. Your mechanic then needs to do a wheel alignment after installing these parts and all will be good

hopefully tomorrow they’ll be able to tell me more. Like a comment mentioned, camber could be the issue.
Glad you found it , if it were the middle sections I would say you are running high on the tire pressures ( I had come across that and I was told my tire pressures were high ) I have not seen anything like this before
I recently had this issue on my car as well. As the suspension ages and wears, there is not enough adjustment left in the factory setup.
Mercedes makes a bolt kit with longer adjustment to combat this issue without replacing all of the suspension components.
The dealership installed this kit, and my problem was solved. Alignment was able to be brought into spec.
well we will see, my tech checked air suspension, height, all four tires balanced, air pressure, and the alignment angles. He adjusted camber. And i put a new tire on before going to the shop. So far rides straight. And i can tell big difference on the feel of the ride with that new tire.
Mercedes specifies excess camber, the cause of rapid tire wear. One of the worst examples is AMG GLS models.
maybe so. I just wanted to add that I’ve owned this CL for almost 9 years, 140k miles, and this is the first time it’s ever shredded a new tire in 8-12 months
