It is normal for stock alignment and setup.
This is a good reminder for everyone to park their car at full steering lock next time you pull into your driveway, just to check that inside shoulder. The outward half of the front treads tell you nothing about the current life of your tires on these cars.

Shouldn't be normal for any car. Depending on the wear pattern, either your camber or toe is not optimal.
I'd take it to a reputable alignment shop. The camber can't really be adjusted on our cars, but a good camber adjustment kit is well worth the money if you need it. A lot cheaper in the long run than contunually replacing tires with tread life on them.

Plenty of aftermarket solutions.
I have same problem with rears.
Outer tread is about brand new and inner tire is worn to belts.
Eat tires like crazy - no tire life.
I am looking at site sponsor K-mac as they are basically eccentric bushings to allow aligner some adjustment,
Other type is adjustable upper bar link for rear.
front and entire different beast.
If you track it they all different types of kits.
I am sure k-mac will post in this soon or go find his posts and links good info

I highly recommend K-Mac, high quality and heavy duty kit.
My W205 would eat rear tires for breakfast, inner edges. The car should've just shipped with bicycle wheels and tires, cause that's the only width of tire it used, lol.
I did the K-Mac camber kit and after ~5K on new tires, the wear was perfectly spread across the tread. Camber was set at 0.5% negative and zero toe.
Parts and labor was around $650 to fix it forever, opposed to buying $700 worth of tires every 8K miles. Also don't lose sight of the safety aspect of this issue too. I know I'm not comfortable riding and chewing up my inner tire edges at freeway speeds, hoping I still have enough cords to keep me out of a ditch.

well said Keith.
MB designs and builds them without ability to adjust camber so pure luck on what you get.
My fronts seem to be OK and wear good the rears - arggggg.
Dealer said nothing they could do nor would do other then sell me new tires.
Local shops said they cannot adjust as it is nothing they could do so they walked away so to speak.
Soon I will buy the kit and have installed and tires aligned for better life as I am not racing this LUXURY car.

The reality is day to day commuting encountering high cambered roads with excess passenger side edge wear or Camber change through altered height - load carrying or lowering. Fitting wide profile tires or curb knock damage.
No longer is there ongoing adjustability for Camber (or Caster). Only basic Toe (directional) adjustment !
It is all to do with cost cutting and ever increasing speeds of new car assembly lines.
FOR ALL MODEL W213 WE THEREFORE MANUFACTURE COMPLETE RANGE OF FRONT AND REAR KITS.
Example Front and Rear “UPPER ARM” or “LOWER ARM” adjuster kits.
Background is “Upper Arms” are more difficult to fit and adjust. Also when wanting to resolve Costly, Premature excess inner edge tire wear arms need to adjust outwards reducing important clearance top of tire to outer fender.
While “Lower Arm” adjusters retain this clearance along with Front and Rear Camber adjusters CAN BE FITTED WITHOUT NEED FOR CONTROL ARM REMOVAL.
Also the unique K-MAC “Patented design adjustment system” has eliminated the need for time consuming disassembly to allow Camber change.
NOW IT IS PRECISE SINGLE WRENCH “ULTIMATE ADJUSTMENT” - DIRECT ON ALIGNMENT RACK “UNDER LOAD”.

Yes either showroom height or lowered:

I have 15500 miles on my Michelin P/S4 A/S on my 2021 E63S wagon. My latest service inspection showed even wear across both rhe front and rear tires. However, the tread depth on the passenger side both front and rear was 1mm less than that on the driver side. No explanation from the tech that did the measurements. I don’t see any unusual shoulder wear on the inner part of the fronts either. I wonder how much the difference in tire construction contributes to the shoulder wear being seen by others.

that's good you are not showing inner tire wears for front & rear. I am already on my second of PS AS4 (having replaced 2 seasons after the first due to inner wear problems).

The Michelin front tires went a bit over 12,000 but I wasn't driving the car as hard during this set as I did the original tires, more mountain runs and fun. More daily commuting and easy road trips on the second set. Rear tires still ok despite some good heavy throttle time spent in race mode around my favorite corners. Dealer didn't have a problem with me replacing only the front tires.

I'm on my third set of front tires at 22,000 miles. Just had the car in for annual service and replaced the fronts with new PS4s. Original Pirelli tires lasted less than 10,000 miles, front tires were done on the inner edges, rear had life left in them. Replaced with PS4s all around at that time.

I'd like to add that the comments and opinions I'm making here are focused on optimizing tire wear, not focused on squeezing out maximum handling performance or tracking the car. If you spend most of your time carving twisties with maximum thrust or track your car often, you'll probably want 2%+ negative camber and 1/8-1/4" toe in. But if you drive your car like that most of the time, you'll use all of your tire and wear them out long before you'll see the effects of negative camber in street driving.
I don't know about you guys, but the majority of my driving is not tearing up corners at warp speed, lol.

So at least for my case I don't think it is ride height that is impacting the tire wear - I'm sure it's the aggressive camber.
BTW, suspecting as much, I had the car in Race mode and surprised the heck out of Tesla Model 3 yesterday who foolishly thought they would pull me after the light changed to cut over to the Interstate on-ramp lanes. Nope, they had to merge behind me

The dealer will tell you "they shouldnt wear like that" which is a reasonable assumption (classic dealerships, just assuming everything), however if you press them for solutions they wont have any, because it is how the car is designed and there is nothing they can do.
Factoring in the soft tread of Pilot Sport 4S tires and yeah you go through tires pretty quickly compared to "normal" cars
