2019 C300 - Alignment, FrontEnd, Tire help

hi,

I bought new c300 as certified preowned in 2021. Since than I replaced the tires twice. I keep having them align every 10000. Originally the dealership put on continental tires. ContiSport contact SSR>. $500 a piece. Run flats that are seasonal and can't run below 45. I store the car in the winter. I replaced the original set of tires once after 10,000 because of coupling. Dealership said it was cause of cold winter driving. I accepted that, and just bought a whole new set of continental contisports ssr.

Since I only got about 15000 miles with being stored in the winter on this new set and the coupling is happening again. I am assuming these tires are not meant for this vehicle. Can anyone recommend a set of tires that can get 40000k, or are a good tire for the C-300? Could it be something beyond the tires, such as alignment, front end complications. I had them run diagnostics on that twice as well. everything checked out.

any help would be great!

thanks MBworld

are they wearing evenly across tread width?

Not much they can do on alignment to STOCK MB except for toe.

wear in middle but not edges means too much air pressure.

Try lowering the front pressure
