I have a 1.5 years old 2021 S500, with almost 20K miles on it.
Was advised to replace the tires. Aren't they supposed to last for 60K miles?
I have run-flat installed. Can I replace them with the regular tires? Would I need to drag a spare around then? (Not that I can change it on the road myself anyway )
Bloody hell 60K miles?? This car being driven in our atmosphere? MB's are heavy, tire eating machines. If they're warrantied for 60K get a pro-rated replacement set.

I don't know what the tires were warrantied for. Was just a guess, based on my previous experience. (This is my first S class, so no relevant experience yet )
My question is: how many miles should I expect from a run-flat tires?
Also, both of my front tires show excessive wear on the outside edge. Is it a bad alignment? Or over/under pressure?

Ah, not sure about runflats. Hopefully another member will chime in on that matter.

Yes, I replaced the run flats on my 2022 S580 with conventional tires. Significant improvement in ride quality—but still unacceptable, IMO. I carry a compact spare and a jack & tool kit in my trunk. And yes, 20,000 miles is not uncommon for a set of tires on these very heavy sedans. What size wheels? 19”, 20” or 21”? What brand tires? Do you drive more aggressively?
Yeah tires last 60,000 miles on an Accord lol, not a car like this. My S560 has 41,000 miles and its on its third set of front tires and second set of rear tires
Yes, the W223 is a very heavy vehicle on passenger P rated tires. The true AMG version may be 1000 lbs heavier.
I noticed on the side wall information of our W222 S-Class that the Continental MOE run flats can be safely inflated to 51 PSI cold at the max load rating. We tried running 40 PSI and the front tires still wore out on the sides at 25K miles. Now trying 45+ PSI after putting a new tire on the front passenger side this week. This is the wife's car and she is a non-aggressive driver on the stock 19" rims.
Our RAM diesel pickup runs 80 PSI 10 ply rated tires and we run 80 PSI cold in the front due the heavy diesel engine. This gives long lasting even wear. Our Jeep runs the same 80 PSI 10 ply rated tires but we only inflate them to 55 PSI cold. The 10 ply rating gets you a beefier tire overall. The Jeep is a lighter vehicle and the tires are long lasting & wear evenly set up this way.
Its not uncommon to have to inflate tires to near max rated pressure to get them to wear evenly especially when the are staggered sizes and you cannot rotate them. The TPMS will need to be reset on the MB dash to reflect running the higher pressures to avoid fault messages. We have not noticed any ride degradation due to the higher tire inflation PSI, probably due in part to the air ride suspension. But I'll be dammed if we run a tire at some factory suggested tire pressure on some made up paper sticker that prematurely wears the tire out in less than 20K miles. Seems like a BIG A$$$$.$$ money maker for the dealers. This is something we've known for a long time.
In our opinion, set the pressures high enough so you get the most even, longest lasting wear. You may get a bit rougher ride but longer tire tread life, less bent rims and better MPG to boot. If you have infinite momentary resources, disregard this post
Currently at 15k miles on the Michelin Pilot Sport A/S n-spec tires size 255/40R20 non staggered and the wear is at 75% which is very impressive. I had these porsche spec Michelins on my previous A8l and got 45k out of them before they got down to 3/10th of wear. I highly recommend Michelin tires especially all seasons for the best ride comfort and treadwear. I am running them at 35 psi. Not worth overinflating the tires for gaining addition miles if these already last long...
If you read and watch the reviews you find that the Michelins in the UHP class tend to not have the best ride and noise ratings.
I would know as I ride on them and switched from a set of 21s and Pilot Sport 4S summers. I am a fussy guy tbh. I don't like hint of vibration or too much noise but these tires are smooth as glass on highways and they are very quiet for this category. They also ride over bumps, potholes etc very nicely. But then again everyone is different. They are N-Spec porsche tires which is why they are better than the standard Pilot Sport versions.
UHP tires are used on average in service in wider widths than various other types which affects the noise ratings in aggregate. They also tend to get worked harder than other types due to the more sporting nature of the cars typically using them. Those cars often can't do a four wheel rotation and in some cases with some cars/tires, they can't be rotated at all. These things all play out in ratings at tire rack and other outlets.
In my experience PS4s are actually pretty quiet and smooth (when not worn) when used with non-sporting vehicles. To me the one big downside to them is they get slippery in the cold, and downright treacherous at freezing and below. Lesser downsides are they can also hydroplane a little bit but not so bad as to be a real problem for a prudent driver even in the Seattle area where I live. My guess is most will change them before they wear out due to noise.

What else have you had to compare them to though on the same car? When independent measured testing from TireRack of all the same tires on the same cars yields a result its hard to refute that.

I think you maybe confusing the all season n spec tire I have vs the standard pilot sport all season 3 and 4 tires which are definitely more noisier and firmer ride? I find these Michelins more comfortable than any pirellis I've used on my other cars and definitely better ride and handling balance then any Continentals. I'm a Michelin guy

I have the 4s on my 2021 Rs7 and I agree with everything. They are very smooth when new and stay in balance throughout their life but do get a little hard after a while. Great handling and good ride for sure but a bit noisy.
These are the ones. They are designed for Porsche especially the Panameras to give best all season ride and comfort. They are v rated instead of the y rated standard Michelin pilot all seasons. The thread pattern is simple and thicker for longevity. It's more like a grand touring tire feel compared to the Michelin ultra high performance tires base on my ride with the A8l after 2 sets and currently on the S580.

There is no evidence that there is any difference in any characteristics between the N Spec tire or any other variant of the same tire. You can't really use experiences you've had on other cars, I have had tires I loved on one car and put them on another car and been totally disappointed in them. When we buy tires we don't have any choice but to rely on comparison tests and word of mouth to help us decide what to buy. All of the instrumented tests put Michelins towards the bottom when it came to ride and noise, and since those were my main concerns that quickly disqualified them for me.
I used to be a big "Michelin guy" but as I tried other tires I quickly came to the conclusion that you cannot say a tire is the best at all "because its a Michelin". It totally depends on the model of tire. I had Michelin Primacy MXM4 GT non runflat tires on my S560 and replaced them with Pirelli PZero A/S Plus because they had the best ride and noise ratings in the tests of UHP tires, and am 100% satisfied with them, they ride softer and quieter than the Michelins they replaced, and those Michelins being GT tires are going to be softer and quieter than any of Michelins UHP tires. Michelins are often quite overrated IMO.
I realize the "Michelin fanboys" will eviscerate me for this, and that zealotry is part of what turns me off of Michelins lol.

Lol no worries. I'll stick with my Michelins and Blizzaks.

I’m glad we are talking about this, as I am currently wheel & tire shopping, going for 18’s on my S560. I realize this is W223 and 18’s don’t fly here, but I believe this is relevant to this discussion. It would appear that the Pirelli P Zero All Season has been replaced by the P7 All Season Plus 3, or at least that’s what it looks like on TireRack today. Here are screenshots. The P7 A/S Plus 3 seems to beat the P Zero A/S for comfort. Am I missing something here?
No, those are two different tire lines. The P7 is a grand touring tire, the PZero is an Ultra High Performance tire. The PZero AS Plus I have has been replaced with the PZero AS Plus 3
