I just spoke with my service manager who is great and is willing to switch my Pirelli run flats to the Dunlops however he really feels I won't feel or hear much difference. He looked at all the speed tests, sidewall thickness, etc and feels the ride won't change much. So whoever has switched was it worth it?? I do not have MBC on my car.

I Did read the thread from page one. I was asking those people who switched who do not have MBC as Chucky does and Kratos put Bridgestones on his car. I am wondering about the approved Dunlops from Mercedes that my service manager is not to impressed with. Thank you for your helpful comment.

Anyone in the SoCal area switch tires or feel the need to switch tires?
Also, I have a 2015 S550 due for delivery in June w/ the 20" AMG wheels. Should I request for non-run flat's now before they even build?

How are the roads out there? If they are mostly smooth - you should seriously consider it.

I asked my MB sales guy and he looked at me like I had two heads. Because I'm not ready to pull the trigger yet I did not pursue the issue with him

This is the one thing I can't figure out from this thread. Specifically, is there a factory ordered set up which comes with non-runflats? All AMG or just 20"?

I guess what people are referring to in this thread is that MB has funds to make customers of the S class happy and if you complain you don't like the run flats I assume they use these funds to replace your tires.

I doubt you can change any of the tires from the factory. In fact, you never know what brand of tire you will get. It has been this way forever. I guess what people are referring to in this thread is that MB has funds to make customers of the S class happy and if you complain you don't like the run flats I assume they use these funds to replace your tires.
There will be a formal procedure in time for this but it will take many months to happen.
For now, the info provided on this thread will be the best tool for customer to make the switch.

Had the Dunlops put on my car today and wow.... Really really does make a difference in the ride and cabin noise. Anybody still on the fence about making the switch I highly recommend it!! The dealer kept my run flats

Night and Day difference isn't it? Can't believe how we dealt with it. Harsh ride and bubbles galore.

According to my service manager this is correct and these are the funds he used to get the tires for my car. He never saw an Official Bulletin as stated in this thread and when he called Mercedes they knew of no switch authorization. So I am assuming that dealers are using the 2500.00 make the customer happy fund built into every car to take care of this issue. For me I cannot wait for the switch as I cannot stand the run flat road noise and harsh ride.
"I just got word from the MB dealer support from Germany and the 2015 S550 and S550 4-matic will only be available with the 2nd generation run flat tires.
We can offer you a credit of $175.00 per tire if you want to order a regular set of tires from our service department and have them added to the vehicle once it arrives. Please note that then you will not have a spare tire for the vehicle unless you order one."
A couple follow up questions:
Those of you who've been successful in having your runflats swapped out for traditional tires at your dealer, have you had any out-of-pocket expenses for that swap?
Has anyone ordered a traditional spare tire for their S550 ? If so, what's the cost?
Thanks !

I received the following reply from my Sales Person as I'm working through eliminating the runflats from my 2015 S550 (build date in June):

No spare is fine with me. Awaiting the tire repair kit which was on back-order. If I get a flat, I'll just call Roadside.

I have incurred no out of pocket expenses to get my tires switched. My service manager used the $2500 per vehicle keep the customer happy fund built into each car to make the switch for me. I ordered the tirekit for the car but did not order a spare. Figured I can't carry it on the car with me so it wouldn't do me much good sitting in my garage if I ever had a flat.
More to follow...

No out of pocket expense. My runflat tires were coming off anyway because of bubbles and under my tire warranty were due for free replacement. They installed the non runflats instead.

When Bridgestone started mass production of run-flat tires in 1987, the tires tended to give a hard ride comparable to conventional tires because the sidewalls were thick and somewhat inflexible. In 2005, Bridgestone introduced its second generation run-flat tire that featured improved riding comfort through an improved sidewall-reinforced rubber.
Bridgestone's third-generation run-flat tires have adopted new technologies that further improve riding comfort. By application of these new technologies, the third-generation run-flat tires can reduce vertical stiffness deflection index* more than the second-generation run-flat tires and achieve riding comfort comparable to conventional tires. Moreover, they enable the development of run-flat tires in a wide range of sizes, including sizes that were previously difficult to develop.
Comparison of the riding comfort of run-flat tires by generation
The indices for each generation take the tire vertical stiffness deflection index of conventional tires as 100. Riding comfort improves as the value of the indices decreases. (Tire size: 245/40R18 93W.) Third-generation run-flat tires in this comparison incorporate new sidewall-reinforced rubber and new ply.

Wonder why Mercedes isn't using the third generation ???

MB tire recommendations and spare tire retrofit that MBUSA should agree to - 20" Dunlop SP Sport Maxx GT confirmation as an alternative to run flats.
