Is this typical tire wear? Continental RF almost done at 12k miles
Dealer put on new MOE Continental RF (18") when I bought the car CPO.
After 12k miles, my rear tires look close to needing replacement. The right tire looks more worn than my left tire overall, especially when looking the inner edge to the middle.
Is this typical for a C300? I understand these cars chew through tires due to its camber, but wanted to understand if the uneven wearing is somewhat expected?

Too soon. Clearly there is an issue here. You don’t say if square or staggered.
It's all to do with no longer any adjustment - other then Toe directional adjustment.
Today’s models the often quoted, reassuring “FULL FRONT & REAR ‘4’ WHEEL ALIGNMENT” - is in fact only Toe directional adjustment (new car industries best kept secret).
No more essential Camber and Caster allowing to adjust tire contact angles, spread load more evenly to resolve costly, premature edge wear.
Catering for other then showroom height conditions - day to day commuting encountering excess inner edge tire wear passengers side through high cambered roads or wheel squat through lowering or load carrying . Fitting wide profile tires along with no longer the capability of ongoing adjustment for curb knock damage.
IT’S ALL TO DO WITH COST CUTTING AND EVER INCREASING SPEED OF AUTO ASSEMBLY LINES.
We saw the need to re instate once again full precise single wrench adjustable front and rear kits.
FIXING IT RIGHT THE 1ST. TIME - NO MORE GOING FROM ONE DEALER OR ALIGNMENT SHOP TO THE NEXT OR IN FRUSTRATION CONSTANTLY CHANGING TIRE BRANDS!
Example Front Camber kit C300 #502816-1 $345both sides - less then cost of one hi performance tire.
FRONT CAMBER #503416-1i $345 ..........CAMBER & CASTER #503416K $480 REAR CAMBER (& EXTRA TOE)#502226K $480
KMAC unique patented design - precise single wrench adjustable on car accurately under load (direct on alignment rack). Front Caster adjustable bushings are Monoball / Self aligning with more then twice the load bearing, impact area. Replacing the soft rubber, oil and air voided OEM bushes. Result is this KMAC design still allows arms to travel through their required suspension arcs but providing significant improvement to brake and steering response.

So far I have gotten about 25K miles on my continental RF tires and the rears are quite warn and ready for replacement but the fronts are not that bad and still have decent tread on them.

I have read but cannot find the solution in your post ? please help !

IT’S EASY / ELEMENTARY. It’s all about awakening owners “Can fix it right the 1st. time”.
OEM a “full alignment” should not be just Toe.
No Camber or Caster to cater for other then Show room height conditions.
Allowing to adjust tire contact angles spread load more evenly !
No more going from one dealer or align shop to the next or resorting to constantly changing tire brands.
If you have the C300, you should not have any problem with your tires like on the C450/C43/C63's
The C300 sits flat, so you must make sure your tire pressure is set properly plus after some time, you should also get a realignment done if you purchased from a dealership outside of MB or if you see uneven tire wear.
The 18's sit flatter on the C450/C43 cars even with the rear camber BS that is setup in the cars and can not be adjusted however the C300 do not have rear camber sport setup.

Hope this helps.
What do you mean by the C300 sitting flat? Do you mean the camber? My last alignment done back in Oct 2021 shows that my car has -1.5/-2.0 camber on left and right side, respectively.
This is why I am still confused after reading all the forums :-)
It's sometimes difficult to know the truth: can we fix or not this problem on the C-Class W205 ?
Thank you for your help.
What I am saying about "Flat" is that your front and rear should be 0.0 camber or very near it. Also the toe should also be 0.0 as the C300 is not setup for sporty driving but more luxury smooth driving.
As others have said, this is a common issue of uneven tire wear on the rear of C300's. The factory rear camber setup is excessively negative IMO. The proper way to correct this is by getting a quality rear camber adjustment kit... or just keep buying tires. :p
Mine had the same issue. I have the K-Mac rear camber kit (highly recommended) and it has corrected my issues. Plus I can have it adjusted at will, if I want to go more aggressive for handling, etc.

So yeah......looks like two different cars!!!
I'm going to the dealership to have them do a wheel alignment. They're running a special for $109, so I thought it was a good value.
At this point, my Mercedes indy said that all the suspension components look good. So hopefully this is just an alignment issue...
I'm also under CPO warranty so I will push the dealer to quickly check all the suspension components, just in case. Hopefully they don't charge me a diagnostic fee

sorry but i must be too stupid and still don't know what is the solution to this problem...

As explained OEM the often quoted reassuring “Full Front And Rear ‘4’ Wheel Alignment” in reality is only Toe (directional) adjustment!

I will update this post after.
Got back from the dealership this week. Did my 60k transmission service early + did a wheel alignment. The alignment came back with only the rear-right wheel out of alignment. So the conclusion is that it was an alignment issue.
I was told that these tires still have a good chunk of life left. I'm gonna keep a closer look till then. Hopefully I can get a good 25k miles out of it (halfway there so far).

Glad to hear you got some service and an alignment check, and I believe the conclusion is correct; it is an alignment issue. Unfortunately though, it's unlikely they solved it. Getting maybe 25K out of tires that are good for ~45K+ is not cool to me, but everyone has their own tolerance.

Even though camber does not affect tire wear nearly as much as improper toe the fact you have a one half degree camber difference between left and right suggests to me the right rear upper control arm has bushings that are collapsing or worn. I can see a 0.1° difference in camber but one half degree? That suggests something is worn.
From the photos it appears your car has the steel coil springs. If so it is much easier to change the upper control arm on your car than on a car with the airmatic suspension.
Have you had any major components in the suspension replaced? If so it is important to properly preload the suspension before you torque all of the bolts down to the specified values.
So I have a 2015 CLS400 4Matic (staggered setup)and I have burned through two sets of rear tires in less than two years. This last set, Michelin run flats, lasted me 8 months with less than 10k put on them. My car started to fishtail on the highway last week in the rain and that’s when I realized how low the tread was. Even wear on both tires. My car has always been dealer maintained and when I asked Mercedes to replace these two tires at no cost to me given the unique circumstance they told me to screw. So now I’m going through the claims process with Michelin to try and get them to cover these tires even though I know the responsibility should be put on Mercedes. Any how the problem seems to be getting progressively worse each time and I can’t afford to burn through anymore tires. Any help would be appreciated on the cause of the premature wear on these rear tires. Thanks.
I told understand telling you to screw. I’d run it up the ladder. What was the mileage warranty on the tires? Most tire manufacturers only warranty the rear tires on a staggered setup for 1/2 the miles.You have had the alignment checked? What about tire pressure? I have 11,000 miles on mine and I can’t tell the difference between the front and rear.
