Run Flats?
And the biggest reason to get rid of the BMW, is because of these rims and tires. But because Mercedes is now doing the same thing, I hesitated and did not make the purchase..
I've had the last two models of the S class, prior to the BMW, and never had this issue.. Until now..
Can anyone give me some feed back? Thanks guys!

On this forum it is well documented that on the '14 and '15 S550 Sport Package with the 20 inch wheels many people are having issues with the runflats.
I on the other hand have a '14 S550 4matic Sport Package with the 19inch AMG wheels and have not had any problems with the horrible PA roads.
I do not believe our roads in PA are like Manhattan in NY since I was there a month ago and I thought my cab was going to be swallowed by the rotten Manhattan roads. With that said a number of years ago I crushed a wheel on a MB E class 4matic on the PA turnpike.
Other people appear to have decent luck with the 19inch AMG wheels and the standard 18inch wheels on the '14 and '15 S550s.
Hope this helps some!
Part of me wants them to have a better ride w/o runflats although they are happy with the ride quality because the roads here are not bad.
Part of me is worried about bubbles, etc. but if they do have a flat, it is nice to know they don't have to pull over and replace a tire.

Thanks for the reply! :-) You're driving a 2014 S 550 4Matic, have you have any issues? How long have you had your car? What wheels do you have? I also want the S 550 4Matic, I was just going to get the standard 18-inch 10-spoke alloy wheels wheels that come with the car, to avoid any problems. But when I found out about the run flats, I chose to wait and do a little more research. I would definitely want a nicer set of rims, but I know they'll be a problem.
But I guess it's too early to tell, since there aren't many S550s on the road yet..
Not all the roads here are great, some have huge pot holes. I'm on Long Island, But drive in to the city for work all the time.. The FDR, Downtown Manhattan, etc..
I'm trying to decide if I do move forward, what is less risky for cracked rims? A 20-inch 5-spoke alloy wheels or the 18 inch?

I have a '14 S550 4matic with 4,000 mile on it. I picked it up in early February. No issues to date. The car has the Sport Package with the 19 inch AMG wheels. I have hit some pretty big pot holes with no problem. Unfortunately for me, I too live where potholes are all over the place. I do not think you would have a problem with the runflats on the 19 inch AMG wheels if you get the Sport Package with them. If you get the Sport Package with the 20 inch wheels that appears to be where all the problems exist.
Personally I do not like the 18 inch standard wheels but many people do. So my best advice is pick either the 18 inch standard wheel or the Sport Package with the 19 inch AMG wheels and avoid the Sport Package with the 20 inch AMG wheels. I have not heard a lot of discussion about the 5 spoke 20" wheels--sorry.

mbusa said they will not swap my tires to non runflats. However, they are offering me a credit of $800 towards the dunlop non runflats and I may keep the runflats on the car now.
Should I keep pushing for a full no cost swap or take the 800 and use it as a back up set?

My car is supposed to be produced next week - very exciting... I can't wait to meet her...

I sometimes drive the car to deep east Texas, where there are no BMW dealerships to be found. What if I blew a tire? The 50 miles you can safely drive the runflats would not get me back to Houston, and there's obviously no spare.
I will never, ever buy another car with runflat tires. My BMW lease is about to end, so I suppose it will be an Audi A8 or Lexus LS for me.

I have always had the S class, so I wanted to go back to it. Until this week when I went to buy a new 2015 S class, they told me the car comes in the run flats.
So I was very disappointed and put a hold on my purchase. The whole point to get rid of my BMW, is to not have the run flats.. so I just couldn't go and buy a new S class, with run flats.. and I'm in New York.. so the roads here are horrible.
However, from my initial research, I found out that Mercedes does not have too bad of a problem with their run flats.. I wanted the standard "ugly" wheels that come with the car, to avoid run flats, but all S class vehicles are now coming out with run flats.
So, I am doing a lot of research, and joined this forum to see if anyone has had any problems with the standard 18 inch wheels.. But some of the guys here are in California, and over there, they don't have the bad roads like we do here...
You said you were going for a Lexus or an Audi? I'm not sure, but a friend of mine told me all luxury vehicles are starting to be released with run flats..
But getting this car, and these wheels, was the worse thing I did!! :-)

I've no doubt that the S550 is a better car than the Lexus, but after my experience with my BMW 750Li, runflat tires are pretty much a deal killer for me--with the poor condition of the roads in Houston, I do not want to take the risk of going through that again.





I had a trip report I posted in another thread where I said people in the Northeast should be demanding their money back if they pay gas taxes for road improvements. I cannot believe what passes for roads up there. They were awful! And I didn't even get the worst of it. I drove an extra 90 minutes to go around NY when I went from Hartford to Washington, D.C. via Scranton.
Enjoy the ride.

I figured I would just give my limited experience/input on these run flats. I'm reading all I can from everyone here on their advice & experience on their S550s.
BTW My roots are from the NYC area.
Besides, It's one way to get me off Face Book.
