I was at tire shop week ago , just to find out my front tires are at inside arches totaly ****** (pics below), already replaced them all around now with Michelin Pilot Super Sport I never saw a tire in that state , mean they are all over top normaly wear off, just the inside arches are ***** on both one more than other,
I am going to set the alignment first, or is there something other what i have to check also ?
Or is this normal for this car, due to some "different" alignment settings ?thx

More likely from toe settings than camber although more camber will make it worse. When it is the very inner edge that is worn badly and the rest of the tread is in fair shape it is likely incorrect toe settings and the tires are scrubbing.
Good thing the front wheels turn so far lock-to-lock on these cars, because it allows you to see inside tire wear pretty easily...and losing a front tire could have been a pretty dramatic event.
I agree with everyone else here who has said you should get an alignment. Our cars go through REAR tires very quickly but I'm only on my second set of front tires and I've put over 30,000 miles on my car.
I had that EXACT same problem on all 4 tyres.
It was dignosed as a PRESSURE/INFLATION problem...I had been running pressures too low, because I'd misread the TPRs. They were actually running at around 22psi....I won't let that happen again.
My tyres still had plenty of tread on them at 22Ks, worn perfectly even across the face of the tread,...except for the inside edge.
I had Yokohama look at them prior to replacement & they confirmed it was an inflation issue.
Cheers, Pickles.

I am already booked for alignment nexe thursday, will see what they find
Sure I am not low on press, all arround 2,8-3,0 bars, as stated on fuel cap
No problem, but I'd be checking the tyres with a guage, that's what I do now, every couple of weeks,,,39psi in front, 41psi rear.(19" rims)
Cheers, Pickles.
just come back from MB service, they find out that convergence - hope i translated it well, was on front right wheel ***** (where the tire was also badly wear off), so 45 minute work and all is back to standards
was told that just with one pot hole you can do mess like that ... with the *** road over here in Slovakia i am not surprised ...
I got the same problem... not the first time... both wheels are like that.. Here is the spec that they used and a picture of my rear tire... If someone has the OEM alignment spec for C63 2012 P31 please can you share with me so I'll be able to validate that they use the correct one...
Avant: Front. Arriere: Rear. Chasse: Caster. Carrossage: Camber. PARA.: Toe. Gauche: Left. Droit: Right. (multiple years of French language instruction and the military sent me to Germany....).
Are you sure that photo isn’t one of the front tires and not the rear?
The left and right rear tire initial specs were within the maximum/minimum range recommended by the factory. Should be no undue wear.
The initial front measurements, however, have terrible toe settings! Left front toe-in was twice the maximum factory setting, right front tire was toe-out.
If that is the rear tire, you might want to consider replacing the inner and outer bushings; if worn, the car will align statically (on an alignment rack) but will move in and out of alignment under dynamic conditions (acceleration and braking). This I discovered on three of the four corners of my 2005 E55. Replacing bushings and ball joints corrected that issue.
There's virtually no toe in the rear. That's just normal camber wear.
Thanks, but I'd argue that's not camber wear. No way it would be so limited to the shoulder, much less with -2 degrees. Camber generally wears at a pretty even slope.

That's a rear and it's normal.
-2° is very significant. Maybe you need a visual to grasp what's happening.
OP, drive that b¡tch harder and scrub the outside more.
