I want to make sure that we are talking about the same thing. Since I spoke about tires in plural, there could be a mixup as there are also two different tires. There is a "PS4" and the "PS4 S". I mean the latter...

PILOT SUPER SPORT 255/35/19 front + 285/30/19 rear = $250x2+345x2 = $1190
PILOT SPORT 4S 255/35/19 front + 295/30/19 rear = $236x2+312*2 = $1096
Am I missing something?

Spot on. The PS4S with a slightly wider 295 will actually provide the exact 26" wheel diameter as the front wheel (unlike the factory spec)

Going with Pilot Sport4s
Width is slightly wider at approx 1/2” on a 295 and will confirm with a tire shop that there’s no interference with brakes or other parts.
Simply keep a fitkit with goo and inflator.
Also checked the brand new Michelin self sealing tires, and not avail now in SL sizes.

MOE = Mercedes Original Equipment - (aka Manufacturer's Original Equipment)
It's a term often used by Tire Manufacturers and Tire Sellers to describe a particular brand/type/size of tire that MB or another car manufacturer has selected as their 'factory standard' for one or more models, (i.e. the tires installed on that vehicle at the Factory when the car is assembled). If you've ever shopped the on-line Seller 'Tire Rack' (by vehicle type), then you've probably seen the term 'OE Tires' shown there, which of course, designates those tires that were 'original equipment' for a specific vehicle..
In some cases a manufacturer like MB will work with a Tire Manufacturer during testing and development to ensure a particular tire is able to meet the expected performance criteria MB expects for a particular model.
Once in awhile, a new model with very advanced levels of performance will reqire an entirely new performance tire to be co-developed in conjunction with one of the Tire Manufacturers. It may then become a 'brand exclusive tire' offering for that one particular brand and model.

Wolf, exactly right as I’ve done a lot of research. The reviews on the 4s tires are fantastic!
Width is slightly wider at approx 1/2” on a 295 and will confirm with a tire shop that there’s no interference with brakes or other parts.
Simply keep a fitkit with goo and inflator.
Also checked the brand new Michelin self sealing tires, and not avail now in SL sizes.

Interference hasn't been an issue for me and everything works perfectly, the ride is a ton smoother, traction has improved, NVH is much lower, and the PS4S is a ton better looking than the stock tires. One regret I have is not refurbishing, repairing, and cleaning my rims before install.

Regarding the MOE (Mercedes Original Extended) designation on tires, I found it interesting that the harsh riding Continentals shipped on new SLs don’t even technically qualify as run flats at all, since they don’t meet all requirements for that designation, but rather are a sort of light duty run flat. So Mercedes did recognize the negative impact on ride quality and tried to do something about it. For me it wasn’t enough - I switched to Michelins and it made a big difference. See the TireRack webpage in previous post for more info if interested.
