Final Edition C63s / RS3 Sportback
PS4s and PSS5
Hi guys
Would be an issue fitting ps4s in front and pss5 rear? Understand same tires same axle shouldn’t be a problem
No pss5 sizes for c63s front…
Thanks

You can technically have different tires front and rear, but it will change the balance of the car as the tires weren't matched to work together from the factory and by AMG. Among other things, the OE spec/sizes tires are matched to each other, so the front and rear axle are working together. If you fit two sets of tires that weren't designed to work together, the outcome may be less than desirable. I wouldn't do it. Always stick with OE spec tires or if you go aftermarket with another spec tire, make sure the sizes, grip levels etc. were designed to work with each other.

The result will be more or less understeer than oem, and one end will probably break traction before the other. Unless you are pro driver, push the limits, or on a track you may not notice.

I called the Dealership and they replaced it with the correct Michelin Pilot Sport 4 S. While I did not noticed any handling change, I was not comfortable and did not want to be thinking about it by having a mismatched tire.

superswiss is factually correct, but like smiles201 mentioned, unless you're pushing your vehicle to the limit, you likely won't notice it at all.
I've run into the situation numerous times where a vehicle comes with tires I don't like (eg Pirellis or Contis), and I want the PS4s or Pilot AS4 (my daily with high mileage). I've typically replaced the tires only as needed, a pair at a time. Typically the fronts wear out much quicker than the rears due to the aggressive OEM camber. So I've run Michelins on the fronts and Contis on the rears for *thousands* of miles, until I had to replace the rears. My daily driving doesn't bring out the subtle handling differences with the mixed tires, and I wasn't a fan of spending another $1K in tires and wasting perfectly good tires with tons of tread. Too frugal maybe? But definitely no issues whatsoever in doing so.
Having said that, I would never change a single tire with a different model/brand. Different grip characteristics on the same axel is a no-no.
