I took a quick look to find the previous thread regarding inside rear tire wear on S55's but without luck. I just had my 55 4 wheel aligned because of inside rear tire wear with the winter tires. The car was very close to spec and required little if any adjustment. The tire wear seems to indicate negative rear camber. There does not seem to be any bent or worn rear suspension components to blame.

Does anyone have an answer to this problem?

Thanks Highlander, that was the thread I was searching for. This thread however seems to be primarily related to front tire wear. Seemingly Mercedes has set the front suspension to provide better steering response than tire wear.

My problem is related to inside rear tire wear that seems camber related rather than toe in wear. There is no feathering apparent on the inner edge.

 

My rears have always worn worse on the inside, despite all the aligning and balancing I could muster. I think that's typical of how Mercedes has set these cars to handle, camber and toe. That said, Bob, I wonder if yours isn't related to the ABC rear valve.

The more I look at this issue the more confusing it becomes. Since the car doesn't sag over a period of time I'm having second thoughts about seal damage in the blocks. There has to be a sensor that controls the application of the hydraulic pressure to each of the tires/wheels under different situations or demands. I'm starting to think it is a sensor or electrical problem. Please tell me if I'm crazy and running down the wrong path but it is real easy to throw money at this problem and still be no further ahead. I don't mind spending a dollar but I sure as H--l hate wasting money, if you know what I mean.
