Crazy uneven tire wear one 1 rear tire. How does this happen?
I noticed yesterday that my driver side rear tire is bald and wearing on the inside and the passenger side rear is not. What gives?
Full story: I absolutely knew that my rear tires were on the end of their life so naturally I decided to have a little burn out fun before I go get new tires. I suppose that I would not expect one tire to wear like this but then again I was doing donuts. Do you all think this is a result of burnouts or should I have something to worry about?
I have had regular dealer alignments, I dont drive the car often, and have always noticed that they wear evenly before now.
Just wondering if I need to get things checkout before I get new rubber. Thanks!

I'm not too familiar with these older cars, but that looks like the result of a one tire burnout. What are the specs of your car? Does it have the AMG Performance package which adds the limited-slip rear differential? If not, don't attempt to do burnouts or donuts with an open differential. Can end very badly due to the unpredictability of what the rear wheels are gonna do. Drifting, burnouts and donuts requires an LSD or locking differential.

Yep, then it's clear. Know thy diffs before going all Tokyo Drift. Not only did you burn up just one tire, but you may have also cooked the rear brakes on that side. I don't know if the W211 already had EDL (Electronic Differential Lock), but it's pretty much standard these days on cars with open differentials. EDL if you are not familiar with it uses the brakes to slow down the spinning side of the differential in order to force torque to the other side, basically faking an LSD. This works ok for normal driving on slippery surfaces, but in an attempt to do a burnout it will eventually cook the brakes in their desperate attempt to slow down the spinning wheel. EDL doesn't necessarily turn off if you turn off traction control as its purpose is to manage the torque distribution between the driven wheels. Then there is the risk of the spinning wheel suddenly hooking up on the pavement yanking torque to the other side and putting you in a world of hurt. It's a recipe for a totaled car.

I have a similar issue too. I just changed rear tires due to the insides both worn way more than outside. Mine is a non p30 and stock also. No donuts. But I went to a Mercedes indy shop with few decades experience who does alignments and he said these dont have camber adjustment just toe. But he was suspecting this is camber issue due to the ride height and my airmatic suspension? He suggested possibly a toe issue but it drives straight, and then said maybe a camber kit after I drive a few thousand miles and see the wear pattern.
Now, the interesting part, this is my second 211 e63 non p30 stock. The old one never had this wear pattern ever, it was always rather even and I can see from the outside corner tread how bad my tires were.
In my google research I believe the w211 or at least these AMGs have a neg camber purposely to aid in performance when cornering/handling, and its rather know to have a lil more wear on the inside. Esp more wear on inside if you drive hard and straight.
Im not telling it as it is, just wondering what someone thinks of the situations we are in.

Afaik its a camber issue. Please note that older suspension parts can play a big part in how the car sits (affecting geometry). I also have the extra inner wear both on the front and back. I just finished my suspension refresh on the front and it needs an alignment, On the front you can use camber bolts (and also caster bolts if you want to) to give a little extra adjustability. On the rear its a different story indeed and I believe there is only 1 aftermarker option for adjusting camber.

Update: I got new PS 4s' and took it to the reputable alignment shop. They said the rear was in spec and no other adjustments could be made. Thus i'm chalking this up to burnouts on rough pavement.

Since, I just finished a total suspension refresh (control arms, bushings, ball joints, etc.) replacement. I would say that you have rear suspension components that are totally worn out, either the rear torque arm or tie rod that is causing your tire wear.
Also is your car lowered, as that would also explain it. I would first have your car re-aligned, to see how badly your alignment maybe off. Before you start replacing suspension components.

Yeah, I had the alignment done and they checked over the suspension components. Said everything was good. Here are the results: https://imgur.com/a/ztgSrMy
As a result my rears showed slightly more wear on the inside. But nothing to the degree that you explained. But, now that I have a entirely new suspension under it now, my wear issue should be none existent.

Unless your just out in a parking lot doing donuts and burn outs.

Did the OP ever explain exactly how much more wear there was on the inside? Like, cords on the inside and 7/32" on the outside? Or was it cords and 2/32"? Makes a big difference.

Yuille---I do agree that it is odd. And just to note, my rear tires have always wore nicely. I only noticed it shortly after smoking tires. Mine is not lowered and I dont have a LSD. It is stock. I will still have my mechanic give it a once over in a few weeks. BTW, these tires (PS 4s') are AMAZING.

Kevm14 - not sure I know what you mean. The tire shop didnt do any measurements and I brought the car to the alignment shop after I got new tires.

What I mean is, exactly how uneven was the wear? 2/32" is even with the wear bars so a tiny amount of tread left. What did the "non bald" part of the tire look like in terms of wear?

The issue OEM there is only front & rear Toe (directional) adjustment.
No Camber or Caster allowing to adjust tire contact angles, spread load more evenly to correctly resolve costly, premature edge tire wear.
It is as simple as that. Alright for showroom height conditions but day to day commuting encountering high cambered roads with more right hand side edge tire wear. Or wheel squat through load carrying or lowering, fitting wide profile tires or not being able to compensate for curb knock damage.
Camber and Caster adjustment is essential - FIXING IT RIGHT THE 1ST TIME.
No more the frustration of going from one dealer or alignment shop to the next or resorting to constantly changing tire brands.
