Question about tires for 2015 S550
The tires it came with were:
Front tires are: ProContact GT SSR 245/45 R 19 102
Back tires are: ProContact GT SSR 275/40 R19 101
1. Is this the right combination? Or do the front and back tires need to be exactly the same size?
2. I need to replace front tires. Do I need to buy same brand? Or can I get any brand, as long as these numbers are the same (245/45 R 19 102) ?
The fronts and the rears are likely different sizes. You can look at the sticker on the drivers door pillar and see what size came on it. I'd surely go back with the propers sizes if you don't have them already.
To answer your question about what brand to put back on it, If you don't care about tires beyond them being black and having tread then yes you can put any brand on the fronts you want.
If it were me I'd replace all four with a good tire. You can go to tirerack.com and find your car/sizes and see what gets good ratings.
Back tires are: ProContact GT SSR 275/40 R19 101
1. Is this the right combination? Yes, Or do the front and back tires need to be exactly the same size? staggered sizes are de rigueur these days.
2. I need to replace front tires. Do I need to buy same brand? Or can I get any brand, as long as these numbers are the same (245/45 R 19 102) ?
If all you replace are the fronts you need to buy the same brand, same size, and to the extend possible, from the same month of manufacture.
If you replace all 4, you are free to buy whatever you like of proper sizing.

I was guessing that the T was a mistake given that the rest of it fit and they come on W222's
front tires are a bit narrower than the rear tires on my AMG wheel package 2016 S550.
My car came with summer tires (run flats) which i took off right away - i got the car delivered when it was snowing, and summer tires harden below 45 degrees.
Yeah, run flat winter tires swapped with summer seasonably might have been the way to go, but i didn't want to be bothered.
Folks have also switched out their run flats for more comfortable conventional tires. personally, i'd rather have a worse ride and fun flats - i'm a nervous guy, but there are no run flat all seasons in my size, so....
i'm happy with the continentals. i'd check tire rack if you can just replace what you have with newer ones, or if the extreme contact might be a step up and then i'd replace both front at the same time, and both rear at the same time. extra bonus to replace all 4 at once.
just my .02 - good luck and welcome to the site!
