Unusual front inner tire wear
Today I discovered my 2 front tires have an unusual wear pattern on the inner edges. They are 235 35 19 ContiSport Contact 5P’s on stock multispoke 19’s and have done only 10,500 km / 6,500 miles. There’s still a fair bit of tread on them but sections of the inside edges are tearing. I took the car into Tyreplus in South Melbourne where I had bought the tires and had an alignment done 11 months ago. The guy wasn’t sure why it is happening but suggests that when I replace them that he adjusts the toe to be less severe. A similar thing happened to my last front tires. Is anyone else having similar problems? Any ideas on what to do?

I had much the same problem with same tyre as you at similar mileage. Your wear does look more severe though. Mine had become quite feathered on outer and inner blocks so had become noisy ie lot of tyre hum/drone. Eventually decided to replace but got alignment done which was in spec. Dealer was pretty much "you get this with aggressive front end set up on low profile tyres". On my previous C63 on 18s I went thru a few sets of Conti CS5Ps on the front which would wear on the inner edge but I don't recall the feathering and noise. I believe there were subtle front suspension changes with the post 2011 models so I am assuming this and the 19s is the reason. I have in spite of all this stuck with the Contis - hard to see it will be different with other tyre types if it is related to suspension set up. What I have done though is this time go with the MO spec of the Conti tyre - maybe this has slightly different wear characteristics? Can update you on this logic in about 12 months or so!!!

I do have the same wheels and here's what happened to my front right the other day:
Although the tire does have 31k miles on it and is completely dry rotted.

Too much toe-in by the look of it. Maybe camber a bit if you are lowered. Camber is not adjustable and I think it is more toe-in anyway. If you want to stay in spec get it adjusted to the lower limits at the very least.

Toe out causes inner wear... And if you have a decent amount of camber it's a double whammy

Same thing happen to my Toyo R888R. My 14 C63 is on KW V3 suspensions you can’t adjus
Same thing happen to my Toyo R888R. My 14 C63 is on KW V3 suspensions you can’t adjust the camber as well, the only way i can think of is to adjust the car to stock high or get a $1000 camber plates.

You don't have to get that expensive. Just replace the two bolts with part number 000-333-10-71 what give you adjustability. The bolts cost about 50$ and you can get a more positive camber (I think it was about half a degree) on the front axel. I got mine replaced last week and I went from -2 degree on the front to -1 degree and 30 minutes.

...and just happened again to me on PSS... second time even after alignment.

Lots of posts on this. Many options.
Cheapest and helps it but doesn’t fix it is replace control arm and thrust arm bolts with Mercedes slotted fixed adjustment bolts as mentioned above. Can do one on each side camber only but doing the caster one affects camber too.
Other options are expensive but so are tires. Kmac bushing replacement or upper control arm replacement with adjustable ones allow you to dial camber in to whatever you want. Not without debates on drama though as you will read. Some say squeaky, some say they wear out quickly.

.... Yes always resolving issues by creating new concepts, ideas does create controversy !
But as a manufacturer proudly this “ ongoing development” we find is a whole lot better than merely watching, doing nothing flawlessly.
What we have achieved is filling a need providing Camber and Caster adjuster kits - Audi through to Volvo with over 800 P/N's involved. Always meeting / resolving along the way the challenges of creating fail safe long term durability (See Web Site www.k-mac.com ABOUT US).
W204 / AMG OEM full front & rear wheel alignment is only Toe (directional) adjustment !
No “ongoing” Camber or Caster facility allowing to change tire contact angles. Essential to cater for uneven tire wear, the result of high cambered roads, altered height through lowering or load carrying, fitting wide profile tires, worn bushings or simply curb knock damage and / or correctly resolving steering pull, Track Days adjustment to increase track width and reduce understeer or oversteer .
K-MAC adjusters replace the four FRONT highest wearing bushings – and are Camber and Caster adjustable, Mono ball / 2 axis design also improving brake and steering response. P/N 502616 K $480
Also replacement upper Strut mounts for coil spring models ( additional Camber & Caster for track days ).
Stage 2 (Street / Race) P/N 503016-2L $545
Stage 3 (Full Race) P/N 503016-3L $545
REAR – Camber ( and extra Toe) adjustable P/N 502226 K $480
NOTE : Both the Front & Rear unique K-MAC patented design kits allow “precise single wrench” adjustment accurately (under load) direct on alignment rack !
Also for REAR uprated bushings for the “6 multi link arms” – less rear end twitch / flex / loss of traction – especially when applying power to lane change / overtake P/N 502628 K $ 480.
Delivery $30 one kit $20 each additional
