Anyone running 4S tires on stock rims? Is it dangerous to drive fast on them if on stock rims? anyone have pics of theirs on?

 

Why would they be dangerous? I can't wait for my P-zero's to wear down so I can get some proper Michelin's on my car.

 

I've seen them being used on the e63 yes..

 

I had the exact same question and I was planning on going OEM Wheels + PS4 also. What's up? OP - have you read anything that might indicate it WOULD be dangerous?

 

No, there isn't anything dangerous. It's a better tire. I'm seriously baffled by this and frankly don't understand how it is even a question.
A high performance tire on a high performance car...

I'm putting ps4's on and wont even think twice about it when the time comes. They don't have the factory size for the rear so I think you have to bump up to a 295 but that's not a problem.

 

i have had the 4S on my stock 10 spoke wheels on my wagon for. Couple months now. It's been great. Better road noise quality compared to the p-zero. It's only slightly more quiet but the tone itself is less drone-y if that makes sense.
The rears are slightly wider than stock tires but doesn't seem to affect it much. It does give it a meaty look in the back which actually fills in the wheel well a little better.
I've only been up to about 115. Feels fine.

Hope that helps

 

Sorry for the late response -- I work frequently and didn't get a chance to follow up.

Guys, it's a legitimate question as I am new to this--never used non-OEM tire sizes. I've heard great things about this tire, it being better than its predecessor, the MPSS. I was truly disappointed that it didn't have the OEM size with the correct load rating. I've read around to find out if it's okay to use the closest available size (which happens to be a 295 in the case of the 4S tires for the rear). For instance, Google suggests 11" width rims to be ideal for 295 tire size, whereas stock rims are 9.5" in width (for the rear). I frequently take this car up over 100MPH so I don't want any possibility of the tires being compensated in any way if the fitment can change the dynamics of the car. Especially if an accident at that speed would surely result in a higher probability of death. I've had a scary accident scare so this has been my biggest concern. I really want to try these tires if they are as great as I hear they are. Hope you guys have some input on this, thank you

 

You need the correct load rating. Size doesn't matter so much as long as you are close and maintain acceptable circumference differential between front and rear (for 4 matic), but I would never run tires that do not have sufficient load rating.

 

Hey Speedy,

I hope i didn't come off as dismissive. I was initially concerned as well but after reading about owners here with PSS tires in the 295 size having had great experiences over the years, along with my shop saying it'll be fine, I went for it.
Now maybe there is some ultimate-at-the-edge-of-grip performance that I might be losing but honestly, I'm never going to be near that.
What I did want was to make sure it would be safe at high speeds and at maximum load. my PS4 has a XL load rating which is what is recommended for our models.
I'm not sure if i've affected overall diameter much to mess up the speedo, but I don't think so, or it's so negligible that it doesn't matter to me.

I don't get nearly as fast as most other users here it seems. However, I have taken it up past 115 on my last road trip and was averaging 90mph for some time. It felt great. Stable and not as hard or loud as the P-zeros for me. I've also made some stupid mistakes while taking turns through Angeles Crest Highway and it held great. It also held comfortably where I've made the P-zeros squeal before. not that tire squeal is a sign of failure but it sure feels better.

The wheel width was a concern and I do see where you're seeing those search results but I think there's definitely room for variance in those charts/calculators. If you use that as the bible, technically our stock rear tires in 285 would be considered too wide for our wheels. I would trust Mercedes to not ship the "wrong" tire size on the AMG models.

as aesthetics go, it's really all personal preference but I'm enjoying the meaty look.
It actually helps fill out the wheel well.
Here are some photos of the 295 size tires on the rear stock wheels with the suspension aired out.

I hope this response helps in making your tire purchase decision.
Whatever you end up with, I'm sure you won't love your car any less.







2016 E63 AMG wagon. rear driver side. stock wheel. Michelin Pilot Sport 4S. 295/30/19

@donger, curious as to why you state "technically our stock rear tires in 285 would be considered too wide for our wheels."

Recommended wheel width for the 285/30R19 is 9.5" to 10.5". The 295 is isn't recommended for a 9.5" width but know there are a few that are, especially since Michelin has no plans to manufacture the PS4S in the stock rear size.

 

hey jimminez,
i didn't mean to imply that our stock tire size is too wide for our wheels. I was just trying to make a point since speedy was using an online calculator that was telling him that the 295 were too wide for our wheels. I just meant that if we strictly follow these calculators online, it actually tells us that our stock tires are too wide for our wheel. And we all know that's not the case.
I just used poor phrasing.
just as you mention, there is some flexibility in which tire sizes fit on what size wheel. I think we have enough leeway to put 295 on the stock wheels. That's what I meant to say.

 

Gotcha. Was just wondering.

There are times were I've run tires on wheels where the sizes wasn't recommended with no issues. I'm just not sure I'm going to like the way the 295 MP4S look on my 9.5" LM-Rs. The forged lips seem to make any tire fatter as it is. Also considering on rebuilding to 10" so won't matter then. For now I'll ride out the P-Zero and see what spring brings.

 

So do the MP4SS have the correct load rating in 295s for stock wheels?

 

Way too much bulging imo
Too bad I was hoping to get these tires as well

 

theres like 10 threads on this topic from veteran W212 folk, such as I

i just got ps4s on my car week ago....they are great....honestly i think a little louder than my pss, but i think also have a balance issue....nothing to do with the tire

ok so in my car came with pzero.....garbage, wheel slip all time.

rears last 18000 miles, fronts were ok so i stored them.

I purchased PSS with 295s....i was concerned but did some research, yeah its a bit bulgy but they work and are safe...

i went to shift sector a week later and whooped an aventador in the 1/2 mile...no joke....

anyways, fronts wore on inner wall due to stock neg camber at around 25000 miles, rears were still alive with 30000 miles....maybe pushing it but yeah i guess i milked them for ever $

for a brief second i was thinking about the conti dw sport, but i got a good deal on michelins and got the 4's.....im happy as they are holding up excellent with WOT and the twisties

had long discussion with one of the USA heads of mich tire development, yes ps4s is replacing all the pss size

but for OE developement, in october u can buy 285 30 19 as a c63 OE replacement. called the PSS m--01

u can close this thread now...thank you

 

sub'd

 

thought i closed this thread...lol

j/k why arent u using the tires

 

Haha. Its still relevant keep it alive!

I went with 265 and 305 on my HREs on my CLS63.

 

So you’re saying Michelin is going to make a 285/30/19 PSS tire?

 

i did not photoshop that

it was from a Michelin rep i had a long discussion with while at the Singer porsche booth at the quail

 

Just wanted to confirm you are correct.

I am ordering a set for my C63 Black Series. I was going to go with the New Continental ExtremeContact Sports instead prior to hearing about this. They’re supposed to perform just as well as PSS, but with better wet traction.

I’ve had good experience with PSS before and figured it’s only about a $250 more for them, why mess with a winning combo especially on a Black Series. Too bad the PS4S isn’t available in this size, oh well.

Thanks again for posting about this!

 

Just wanted to give you an update. These tires are indeed available. I just had them mounted on the rear of my C63 Black Series today.

Michelin Pilot Super Sport 285/30/19 (98Y) MO1.
Michelin part # is MSPN 07078

My Discount Tire rep said it was a hassle to try and order these tires. He said their normal channels at Michelin didn't want to sell the tires to them. Most likely because of the limited supply on hand and wanted to save them for dealers? Who knows. Anyways he said they went all the way to the top and spoke with the Michelin rep that is in charge for Discount Tire Corporate.

 

Run flats?

 

they have run flats, usually designated by ZP i believe.

these should be regular non run flats

what kind of price did you pay for them

 

No, the MO1s are non run flats. They do offer them though in this size if that’s what you’re after, but I’m pretty sure the load rating is lower because they’re for the front of a Corvette.

$388 for each rear. I bought them at Discount Tire since they had a $70 rebate going on if you buy a set of four. I posted some pics of the tires in my thread over in the W204 C63 section.
