Tire size is 235/40 R20. Both front tires were extremely worn in an uneven way with 1 having metal showing. Discount Tire inspected the tires and stated that we were, "Lucky to be alive given how dangerous it is to drive on tires worn so badly with metal exposed." Discount Tire in Lafayette, IN inspected the tires. We ordered new tires that would take at least a day to be shipped. Wouldn't even let us leave their parking lot with the car in the condition it was in due to safety concerns. Luckily, we carry a spare, and were able to use that to get home. Michelin reviewed the warranty claim submitted by Discount Tire, and denied the claim due to improper servicing. No warning alerts. The main issue is that the vehicle was recently serviced by the Mercedes dealer in Lafayette, IN on 3-24-26. They collected the payment and handed my wife the key. They did not volunteer ANY issue of ANY kind. She questioned if they even checked the warning alert about the brakes. They stated that the brake pads were in the yellow, and needed to eventually be changed, but it could wait. Several days later, I was riding in the vehicle and noticed a loud road noise. Could not initially detect any damage to the outer/visible areas of the tires such as a nail. But the sound persisted. When we stopped again, I turned the steering wheel to expose the inner part of the tires. There was zero tread on the inside of the driver front tire with sharp metal exposes. Immediately took the car to Discount Tire. They confirmed it was an OBVIOUS alignment issue causing the uneven wear. Shocked Mercedes didn't fix the problem. Should have never given us the key back due to the high level of danger. Midas fixed the alignment $120. Both the dealer and MB USA hq were notified.
