S560 Sedan No Option for non-run flats
I wanted to inform you in the hope that this will help fellow MB owners who may be in a similar situation.
I own from new a W222 2019 S560 which was optioned with the 20" wheels. The OEM tyres were Pirelli Zeros. Front 245/40 R20 99Y and REAR 275/35 R20 99Y. I have never been happy and tolerated the harsher ride when compared to my previous S350 with non-run flats.
After 36000 kms I am due to replace all 4 tyres. Naturally, after researching to see if I can get a better ride with non run flats I have concluded that my only option is to continue with OEM run flats.Here's why !!
After extensive research, forums, private messages from the US and UK and talking to three reputable tyre outlets my confusion and inability to decide got worse. Finally I was able to access the official tyre info from MB Germany (approached with a little cynical reservation). I the spoke with MB Australia.
I was told "you cannot option to non-run flats" (even though I was happy to buy a full size whole and have the same non run flat tyre put on it, kept either in my home garage or in my boot when travelling inter state for example).
The reason for this is, MB confirmed that the S560 driving dynamics (ECO, COMFORT, SPORT and USER Dynamics) software (Suspension, ESP, braking etc) is CONFIGURED AT THE FACTORY FOR RUN FLATS. If I were to switch to no-run flats it would throw up a "manufacturing or manufacturer's defect" !!!.
Adding to this I was able to source an internal Tyre Fit Options information sheet and to my surprise found the S560 W222 and W223 do not have a non-runflat option or summer tyre specified / recommended.
Thoughts anyone ??




Australia is a long way away. Car sales volumes are unlike the USA or UK / Europe.
The Mercedes sales model has now gone to a "buy direct online from Mercedes" no haggling and dealers get to just do the delivery. People are pissed - both customers and sales folk.
I understand that when I bought my S560 new, there were only 5 of these sold that year. Volumes fro the higher end models are low.
The competition is stiff ... I just got to see the new BMW 7 Series 740 highly optioned with Rolls Royce Style self closing doors !! and when I checked it out fully ... it is great !. Didn't drive it and yes, it has run flats but there are BMW recommended Options for non-run flats if you choose.
The young gent who took my call did not know anything about a run flat option. He kept me on hold 3 times as he went back and forth with the "senior Technical Service Manager at head office" and he says "a quick phone call to the dealer" who both said, "your cars driving dynamics are set up for Run Flats"...
Since I know less about this than them, and I have less information than they would have internally, I am unable to refute I badly want to but bull**** does sometimes baffle brains.
Can someone school me into why what they say is BS ? I still have a few weeks before I dive in and get $AUD 2350 for a set of 4 tyres.
Once I get a little more concrete information and if I can be bothered I may call the Head Office and call them out on BS.
Have you had non run flats on your car ? What sizes and brands and I wonder if I can buy a tyre repair kit from Mercedes Benz USA ?

I scrapped the run flats, put on Michelin pilot sports.
Saved one runflats and wheel, put it in the truck as a spare.
Problem solved.
Anything else is overthinking.
My Benz has 0 rattles and squeaks.




I've never seen any error message on my car display. I would stop visiting the dealer that provided you the info about error message.
I did notice on a build sheet on this site that a S600(?) is standard with Non RF that comes with a pump and sealant canister.




The important bit of the tires is rolling diameter, meaning don't change tire size and you'll be fine. (you can also change size as long as you maintain rolling diameter without negative effects)
I am ok with the run flats, but a separate frustration for me is that while there are all season run flats that fit the front, there are no all season run flats that fit the rear wheels. As a result, I run the summer tires. Fortunately I have always also had a SUV.

I wouldnt worry about the MB specific kit, just buy any kit. This is the one I have:

I like having the spare in the trunk as I travel to see clients and I mostly drive so it's easy for me to put the spare on (run flat) and fix the tire at a later time.

clarification please - if you get a non run flat tire puncture, you shall change it with the spare run flat which means you now have one odd (run flat to 3 non run flats. Is that ok ?
and thank you all for helping me.
