While I have seen what you describe in the past, in your case there are two tires listed on Tire Rack for your car and the specifications are different--namely the UTQG rating is 480AA for one tire and 400AA for the other.
In the case of the Continentals, there is only one ContiSportContact 5 SSR listed for the MB C300 with 19" wheels and I compared the specifications of those tires against the OEM tires on the car and they were exactly the same down to the Mercedes, MOExtended Mobility on both tires. I bought Pirelli's instead of the Continentals, but in the end, it is the constant alignment (every 10K) that is needed to prevent them from wearing. This is not something I have ever had to do on any car and certainly none of the many $50K+ I have owned and is not "well engineered" or the best "design" for cars like this.
ContiSportContact 5 SSR are SOFT ( UTQG rating is 280AA or worse). As I mentioned early my wife only got about 15k miles on hers so our experiences match. It's not an alignment issue (Costco tech tried to say I needed an alignment with regards to the rears, but his eyes glazed over when I mentioned negative camber). Alignment only covers uneven wear.
Mine was an alignment issue and it was the same on my AMG. Luckily, I kicked the AMG to the curb before replacing the tires.
