I also wanted to point out that the new s63 AMG has 21 inch rims but the tires are thicker
255/40r21 front and 285/35r21 rears compared to 255/35r21 and 285/30r21 on the regular s. Not sure why Mercedes did that and went with the thinner tires on the regular s but given this, you can upsize the tires without any rubbing..
Good thing it will be 3.4% slower which isn't too bad. I've done it on my Lexus and BMW in the past and had no issues. 60 mph on the upsize tire vs 62 mph on standard etc isn't bad.
I know its 3.4% but the thing is, that it will not only affect speedo.
Odometer reading will be not correct.
Fuel usage will be not correct.
Gearbox shifts will occurs in different speeds.
Also there is something called homologation. In europe insurace can block paying you your money because you did not used tires homologated for that vehicle.
I'm wondering if you can change it in service computer.
I'm really interested in that since I've changed my 21" to 20" but kept 21" in garage. They look so good, and maybe with fatter tires, they could match 20" comfort.

These 21 low profile tires WILL NOT survive even small pot hole impacts if hit in a certain way. Now Im so gun shy, my eyes are glued to the immediate road surface ahead instead of focusing on everything else.
It sure takes away much of the pleasure of driving my new $140,000 + car. And, believe me, this will happen to many more new S580 owners with 21 wheels and tires.
hi, just got this vehicle 2 months ago & experienced 2 flats then. Was wondering if you had any suggestions (other than going 19 or 20). Maybe a thicker tire 255/40/21? Not sure if that would work .

I have filed a safety complaint with NHTSA as to my tire - 3 - failures with this set up. It would be a good idea for those with the same failures to call the NHTSA Hotline and lodge a complaint. Reading on this Forum, there are many more of us with these tires blowing out. The more complaints NHTSA gets, the quicker s recall may happen.
This is a serious safety issue and these tires need to be replaced ASAP
2 tire failures within 2 months of having this vehicle. With the 21. Shoot the # & will call

have these tires held out better since your purchased them??
I would guess you had 21” Pirelli’s that failed. My three failures were and so are dozens, maybe hundreds, of others reading earlier posts on this thread and talking with two different Mercedes service advisors. If you don’t want to change to 19” or 20” wheels, put on some Michelins.
‘BTW. I have received no response from the NTSB on the complaint I filed months ago about this safety hazard!

My fears about the 21’s came true after 2000 miles. This is the passenger front tire. I am glad I check the tires often with the known problems. I had a wait a week for a tire. I have no clue how it happened.

They are much better than the pirellis. I did swap out to the 20s and using Michelin Pilot sport all season tires as I drive alot on highways. I still highly rec the pilot sport 4s for those who have the 21s as it's smooth and quiet.
Hey there! Choosing the right tires and wheels for your car enhances its performance and style. If you're looking for top-of-the-line forged wheels, check out COR Forged Wheels. They offer various custom wheel options with premium materials and finishes. Plus, their wheels are designed and engineered for maximum strength and durability, which is especially important for high-performance cars.

Michelins feel like you are on cloud. The steering is more precise and more heavier now.
As you can see in the pics, the 4S is more beefier looking then the Pirellis. I have not had any blow outs, puncture, etc with these tires on any of my cars since 2018 when the 4S came out. I usually get 35k miles on a set so about 3 years since I always switch my wheels/tires to winter set from Nov to March. Lots of people over on the Audizine forums with the new RS6 and RS7 have not had any issues with their low profile rims and these tires in size 285/30R22s.
hi, i just got 255/40/21s in the front. Is that the same size you got for your front tires? How has it been? No blowouts since?
also, the rear the s580 comes with is 285/30/21. Did you go up to 285/35/21 or did you leave the 30s? If so how does it ride with either or?

The service advisor told me that the problem is so widespread that no one is surprised anymore when these come in. His exact words were this should be a class action lawsuit. So please, please, please if youve experienced this problem, go read my thread and send me the info. I want to get the ball rolling with MB corporate ASAP. If all we do is ***** on the forums, nothing is ever going to be done about this.
Heres another unfortunate soul at the dealer.
any luck w this class action? Got someone here who can join in on the pot! 2 blown Pirellis in 2 months

I changed the front to 255/40/21 but left the rear 285/30/21. Do you think this will be an issue?
Per my previous posts, I’ve had 3 blowouts with 21” wheels/Pirelli P Zero tires. Service managers at two different San Diego MBZ dealers say there have been dozens more with this combination. Mercedes does nothing about it. My complaint to the NHTSA months ago …no action! (BTW the hot line for safety complaints is 888 3274236 and maybe a slew of calls to them may force them to do something)
I’d sure be willing to join a class action suit against MBZ and/or Pirelli. The combo of super low profile 21” wheels and a tire with a “too thin and too flexible sidewall” like the Pirelli P Zero is a time bomb. And that bomb has already gone off for too many of us!
Honestly? I would just buy Michelins to replace the Pirellis if you have this issue. The cost of my time trying to file lawsuits and complain to the NHTSA is worth more than the cost of a set of tires.

Of course change Pirelli to Michelin, which I'm doing. My point is for those that have not, it is a major safety issue that needs to be addressed by MBZ and Pirelli. There is simply too much flex in the P Zero sidewalls and when the super low profile 21" wheel and Pirelli combo hits an obstruction or pothole, many fail. Seems not so with Michelins. Either MBZ or Pirelli needs to address this situation before an injury or worse happens.

You have more time and energy than I do lol. Not trying to save the world today.

It could be a bit confusing for the 4matic. I highly rec putting 285/35/21 rears to keep it even as the s63 comes with 255/40/21 fronts and 285/35r21 rears.
