2015 c300 4matic with sports package
I had the most interesting conversation today with the parts guy at the mercedes dealer when I was inquiring about the Vehicle Toolkit part#: 205-580-01-00
https://www.mboemparts.com/oem-parts...IFJlc3VsdHM%3D

First, he could not find this item, he could only find a full jack that was retailed 204$! I had to provide him with this part number....then he was telling me this was only a bag! I had to explain again to him it was the full kit, the jack, the bar, etc...He had to look it up in 3 different systems.
After he started explaining to me that removing the run flats, would make my car undrivable, because the ABS, Stablity control, 4matic, speed sensors, etc will stop working, even the oem wheel would not work! It was very hilarious, I am not sure how many customers believe this kind of lies ! He was telling me the whole car was designed to work on the extreme stiffness of the runflats side walls.
I was telling him I was switching away of runflats because of that! He also was telling me about some kind of warranty on the pirellis.
He was nice so I did not want to argue too much. He was much nicer then another parts guy at the Silver Star Montreal, who was just basically telling me to ****-off with all my questions... I had originally asked him if the GLC300 vehicle tool kit would fit the jackpoints of the C300, if he could ask a tech to check it out....anyway have a good day!

Do you really mean that he was nice or actually plain stupid ?!
I was thinking that I could only get this kind of stupid replies in my developing country...

No no, he was actually nice service agent, looking the parts number and getting interested in my request. The kind of guy that you want to deal with. The 'bs information' part was just on the side, he was just letting me know I guess the 'corporate' reasons to stick with the runflats...he just wanted to let me know about it, and also about some warranty on the pirellis that no one knows about. I think if you have a flat and you need to replace all 4 to keep the same grip, you pay a pro-rata of what is left of the tires.

So what's the consensus on the best replacement of those runflats? Anything from Firestone that's good?

That parts guy was clearly pushing for a commission sale by lying about the tires, ha!

2016 C 300 4matic Lunar blue
Hello All-I am new to the forum-I took delivery yesterday of a 2016 CPO C Class 4Matic, Lunar Blue, with the traditional grill and star package. I traded in a 2015 GLA250 FWD, after a three year love-hate affair. For the GLA250 at the Tire Rack, there are only 4 MOExtended mobility run flat tires, and the Dunlop is on sale because they are a closeout, which may mean there will soon be only three. My GLA came with Bridgestone Duellers, which wouldn't pass inspection at 18,000 miles, due to wear. I replaced them with conventional Michelin A/S 3+'s. The change in ride comfort, traction, and handling was phenomenal. My C class has 17" wheels, and there are 29 different run flats for it including winter tires, at the Tire Rack, 6 of which are MOExtended mobility. MOE is the tire that Mercedes developed, and recommends for their cars. My C has 17,000 miles on it, off of a three year lease and came with Continental MOE tires, probably the originals. My sales rep at the dealer strongly advised against replacing the run flats with conventional tires, because, in case I hadn't noticed, the car doesn't have a spare. Duh. My last two cars, the GLA and a 3 series BMW had runflasts, which I replaced with conventional. I carry a very effective Black and Decker rechargeable compressor and also the Slime kit, which contains a tiny compressor, which is pretty ineffective. I know there are issues with use of Slime and it's relatives, as pertains to damaging the sensors, but, in a given situation, there may not be a choice. In theory, the MOE tires are only supposed to be run for 25 miles, so you could easily get stuck somewhere in the boonies with them. Within the last year I caught two different sheet rock screws in the Michelins on my GLA, both within the tread. I got notice from the TPS system that I had low pressure. Air leakage was very slow, and I was able to restore proper pressure and, in the fullness of time, got the screw removed and plugs put in, without issue. I wish there was an option for having a spare, jack, lug wrench. My wife has an RX 350 Lexus, and it has a full size spare. We are going to keep that car a long time.

C43 AMG Sedan '19, Saab 9-3ss '03 Stage7, Saab 900 cabrio '92
Looking at this matter my main question is if switching to non-runflat tires request to change the wheels. i remember long time ago for some brands it seems it was required.

I ordered a C43 AMG with the PVD wheels, the multispoke 19" black ones. Looking at all the feedback I have during all this years about runflats and also one testing I did with one friends car, it's clear i will switch them to non-runlfat as soon as i can.

I put a set of Bridgestone Potenza RE980AS on my C300 on Friday. So far, I'm liking them better than the OE Conti runflats.

Thumbs up Bye-bye Run Flats

I was afraid of ditching the run flats because of the lack of a spare. 2015 GLK350 didn't come with a spare, but I was able to find one+air compressor, jack, lugs and all on Ebay for $200. The best of all is that the spare fits perfectly in the cargo compartment under the lid. So, instead of 1,400 that it would've cost me to replace the run flats, I'll spend about 800 on 4 Michelins non run-flat. And I'll keep you guys posted on how it goes...

MBSebas87, did your C300 come also with Ru-flats and if so, do you happen to have the space for a spare under the floor of the trunk? I'm considering buying a 2016 C300 and they all come with run-flats, it's my guess.

I don't think the US-market W205 has room under the floor for a spare...
IIRC, someone on here ordered the Euro-market spare & it came with a bag/straps, and sits on top of the trunk floor.

I just got rid of my run flats... ride is quieter for sure. The "harshness" is still there, but that is because I have the 19" rims, so there is no much sidewall there. But I'm happy with it. If I get a flat/puncture, I have in the trunk the Bell tire repair kit (red plastic self tapping screws) and an air compressor, so it'll get me to the nearest tire shop with no issues.

I just did the same on my 2015 C400 4matic. The staggered 18in continental runflats that came on my CPO car were abysmal, lasting less than 20K miles and had terrible ride quality.

I replaced them with BF Goodrich G-Force Comp-2 A/S and they are much better so far (smoother, quieter, and grippier).

Roads here are on Oahu are in generally terrible shape with 3-4in deep potholes everywhere. I even had one of the Contis replaced under warranty after a really bad pothole strike that bulged the sidewall, but I just decided to replace all four due to the poor treadwear of the set overall.

After another 30k miles, I replaced my P7 Cinturato with a Bridgestone Driveguard. Ride is about 30% more comfortable (quieter and softer) but don't expect non run-flat comfort levels on those.
You also loose some grip if compared to performance/sportier tires but I don't drive as aggressively as I used too like 20 years ago. I expect the Driveguard to last more miles too.

So your tires could explode anytime on a pothole but you still prefer to replace them for your "comfort". So weird, my life is more important than my comfort, but maybe I am too logical...

I'm not sure a catastrophic blow out with run flats would be any safer than one with non run flats, at turnpike speeds.

I have airmatic and I replaced with AS/3 non-runflat. Riding quality and traction are so much better!

Just in case, I also have a slime fix kit in the car. It can be used as a compressor to air the tires without filling in sticky liquid.
I think in most cases we may air a flat tire to run another 10 miles and find a place to fix. Buying another spare tire and changing kit may not be that practical for me.

I put these from costco on a little over 2 years ago : BFG ADVANTAGE SPORT AS 225/50R17 94V BSW ALL SEASON TIRE
for some reason the Manager at the costco tire shop told me these were really bad and I would likely return them, but they were pretty damn good for the first year. And still pretty much are. There were no reviews back then (they just came out then) now they are one of the best rated, lol.
Big improvement for the first year for sure, the run flats were just horrible. But snow/ice traction went bad fast after the 1st year, but it is a RWD car, so it really depends on the driver a lot... (women shouldn't be driving RWD in the snow/ice, heh, my wife managed to get my AWD SUV stuck on a speed bump in some snow, took me 10 seconds to get it out, lol)

If she ever gets a flat, I'm definitely not coming to change or fix her tire, thats what geico roadside is for... But no flats at all, tire pressure is holding ok, 1 tire leaked a little and costco fixed it (was only 1 psi loss per week). plus free rotations and nitrogen is great...

Has anyone tried this spare?? 185 60 R17 5x112. If 135 80 R17 fits Sport package, this should also work.

MB part #A2304010602 R230 SL500 spare.
