Run Flats?
https://mbworld.org/forums/wheels-ti...in-priced.html

With 9200 miles on my '16 S550 4matic I punctured one of the front tires with a long screw. MB dealer told me they cannot fix/plug the hole so I have to buy a new tire (they will not plug runflats--period). Of course they convinced me to buy a second tire since I would have one tire with 9200 miles and one new one on the front. So I ended up spending $800 for two front new tires. I hate the fact that I had to buy two new tires where on conventional tires they would have plugged the hole. On the other hand, it is nice to now that if I had punctured the tire somewhere out in the middle of nowhere I could have driven on the tire. It just so happens that this puncture happened within 1/2 mile of the dealership this morning so this was pretty much a non event except for handing the dealer 800 more dollars.



That said, I will be replacing my conventional tires with run-flat on my Maybach 57. Especially since the OEM tire size is not available anymore. I will replace with Continental Runflats this Fall in the 285/45-19 size. The OEM 275/50-19 is not available, at least according to TireRack.com



In all my years of driving Mercedes and prior to that Audi's I have had two on road failures. Neither would have been fixable with the pump and goo. In both cases I was able to keep driving at reduced speed to a tire store. About 4 miles. One was on the 210 in Pasadena and one was on the 5 in San Diego. With 30 and 35 profile tires if one drives carefully they will stay on the rims and provide continued mobility.

So I decided to buy another S550. I just got a 2016 S550 and I HATE the run flat tires. The ride is so much different. Thank God I can replace with regular Michelin tires. I just have to wait until they need replacing .
Good to know I wasn't the only one who thought the drive was different.
I called up MB corporate and they are escalating the case and they said they will try to swap my tires to non run flats.
I did a search on tirerack, but for curiosity's sake, I searched under S65, instead of a 2014 S550 which I currently drive. Surprisingly, the OEM size for this vehicle is 255/40ZR20 front and 285/35ZR20 rear. The 2014 S550 with 20" sport wheels has OEM 245 front and 275 rear...
I wonder why this is? Should I ask for this higher profile tire instead?
