P4s in case it isn't obvious from above.

Stick with what it says in the E92 manual/door jamb.

Got the following tires mounted to the new wheels earlier this week, took some pics in reference to how wide the rubber sits past the wheels for anyone else debating on what tire sizes to go for on similar sized wheels as mine.

I'm not a fan of any amount of stretch whatsoever, so I'm extremely happy with the sizes that I purchased since having a slight amount of rubber extending past the wheel surface is exactly what I was hoping for.

My setup:
Front - 19x9.5 ET23 TE37 Ultra wrapped in 275/30R19 Michelin PS4S
Rear - 19x10.5 ET23 TE37 Ultra wrapped in 295/30R19 Michelin PS4S

The rubber extends past the outter rim of the wheel by about 3mm on the rears, and 4mm on the fronts. All pictures below are of the rears:

Thanks for the info! What tires were you using previously? And how would you compare the "rubber lip"? Is it even a noticeable difference?

These tires went onto brand new wheels, so there were no previous tires.

The difference is subtly noticeable; I believe most setups, even mildly stretched ones, will have a small amount of rubber extending past the wheel surface right where they meet. However, with this setup, it basically looks like the tire sidewall comes straight up in line with the wheel surface all the way through the sidewall, as opposed to the ever so slightly stretched setups that you see on most 265 front / 285 rear setups where the sidewall appears to be sloping further "inwards" as you move from the wheel edge to the tread.

Do you notice any rubbing? I just picked up some similar sized ZE40s and trying to decide on tire size [although they are ET25 offset]

Havn't gotten them mounted to the car yet. Waiting for a friend to be free one of these weekends so we can raise up the Ohlins R&T coilovers a bit and knockout a BBK install whilist changing over to the new wheels.

Hey I'm interested what these wheels mounted look like and if you encountered any rub? What suspension setup and any adjustments? I'd like to consider same size tires on same sized BBS FI et 28front/23 rear. Thanks!!

Sorry mate, selling the car now so the wheels are listed for sale and will remain unmounted to preserve their "brand new" status.

people care about stuff like tyre noise on e92 m3?....come on now...

lol I can't hear my PSSs over the eisenmann race exhaust. For me, comfort over noise.

[rhyary]

FYI,
I basically demolishing the front 4S in one track day on stock ZCP EDC on stiff and -2.8 camber.
So after 3 sets of 4s lasting two track days each, i am going to try the Yoko and also installing Hotchkis 4 way adjustable sway bar before my next track day.

In short, the 4S are great summer high performance tires for the road but can't last on a technical track like New York Safety Track.

[E36M2]

FYI all, I just swapped my badly worn PSS for 4s all around and I'm pretty disappointed. I am running Volk LE-37s in 19x9.5 and 19x10.5 with 275/30-19 front and 305/30-19 rear.

The sidewalls are soooo marshmallowy soft, it's just ridiculous. Gone is my slot-car-like point-and-shoot handling as well an the very stable on-center feel on highway driving.

The grip is there for turns and braking and acceleration, but the sidewalls are so soft, the car takes a second now to change directions after I turn the wheel. It's like a delayed response where before with the PSS, it was immediate. Also GONE are the rim protectors that I loved for protecting my limited edition Volk wheels. The PSS had a very pronounced rim protector and these do not.

Someone on this thread sarcastically asked if the sidewalls were bubble-gum soft. I'd say that's an accurate statement. Michelin made a serious compromise and I don't like it. It's a night and day negative difference and immediately noticeable.

I can push/pull my car sideways by the wheel and the whole car twists sideways back and forth on the tires for 2-30 seconds after I let go. It sways about 3/4 of an inch.

And I still feel bumps now, but can actually feel my WHEELs hiting the bump. What a joke!

With the PSS, I could hold my steering wheel steady at highway speeds and the car would track straight and true. Now with the 4s's, I have to keep keep making right, left, right corrections...

Sucks after shelling out $1,500.00 for tires, my car now changes direction like a Camry. I've been running pilot sports on various vehicles since I got the 97 M3 and the PS2 came out. Time for a new manufacturer. I will NOT be buying these again.

No, this is not on a bimmer, but on my modified 350z. I am also lowered 1" on Ohins Road and Track coilovers with Hotchkis sway bars as of 6 months ago.

So why am I posting here? I drove an e36 M3 for 10 years and 240k miles and my next car will be an M3/4. I've owned my 350z since new in 2007 and I have been taking great care of it and adding only quality parts. But the 350z can be had so cheap nowadays that it can be purchased by someone flipping burgers at minimum wage. Those types don't spend money on their cars. they might buy nice wheels, but then install Riken radial tires.... Clearly not a bunch I can talk performance with. So I come here for serious performance discussions.

For the rest of you, buyer beware on the Michelin Pilot Sport 4s. Good traction and a comfy ride, but you'll trade all steering response for it.

Interesting, cant say this has been my experience at all. I've had AS/3+ on the car for the last 4 months, will put the PS4S back on this week. I don't remember them feeling any different from the PSS I've driven, and was all round very impressed for the 2k miles or so I did on the PS4S. The fact your car is not tracking straight suggests maybe you have a suspension or steering issue?

This is literally the first post I have ever seen where someone did NOT like those tires.

Are you certain something else isn't amiss in your setup? Obviously it's not a platform I'm familiar with so I have no idea if that setup is aggressive or not. Probably worth remembering that tires need a few hundred miles to break in. Have you gone back to the shop to try and get a refund or exchange? Most offer a money-back guarantee.

Pretty sure Michelin has a 30 day or something return policy. This isn't my experience at all either. On my E39 M5, I switched from PSS to the PS4S, and they feel fantastic. Sharp turn-in, no additional mushiness compared to the PSS, etc.

[6ixSpd]

E36M2, what's your tire pressure set to? That sounds like textbook low tire pressure symptoms, especially given that the PS4S improves upon the PSS in every way. A reduced steering feel/lack of turn-in response is definitely the first I'm hearing about on PS4S...

I run 35 PSI front and 32 PSI rear. Cold. My setup is exactly the same as with the PSS. I drove it in/out the same day for the tire install. I already bumped up rear PSI by 2 PSI over the PSS to see if I can stiffen them up (I ran 30 PSI rear for the PSS. I can't believe how much side-to-side movement there is in the sidewall. Especially in the rear. I know my rear wheels 10.5" width are at the narrower limits for a 305 tire, but still within suggested range for the tire. The car weigh about 3400lbs. Maybe these PS4S are really made for stretch tire setups which helps control carcass flex/roll?

I have no issue with how they grip. Maybe I just need to get used to them. I've had both PS2's (N2) and PSS on these rims and the PS4S definitely feels like it has weak sidewalls. I handled the tires before they went on the car and could squeeze/deform the sidewall by hand easily. The performance shop was also thinking 'WTH... and suggested I tighten up the suspension. But it was fine with the PSS.'

[6ixSpd]

305 is a lottttt of rubber for a 10.5" rim. I'd say therein lies the problem, but if you had 305 PSS before and didn't exhibit any of these issues then I dunno what to tell ya. Perhaps there's a quality control/production issue with this set of PS4S?

Nothing was amiss when I drove it in with the PSS. Yes, this setup is very aggressive. most folks run 245 front and 275 rear. Front Negative camber is -1.7 and rear is -2.5. But that has no bearing on tire feel since this remains unchanged.

I do only have 150 miles on them, but more miles won't make the sidewalls less rolly polly... The grip is there. I can learn to drive around them.

Bah... my photos are too big to upload here and I am too lazy to fire up photoshop.

[E36M2]

For content relevance, I did test-drive a nice Sakhir Orange M4 this weekend. 3-year lease return with 19k miles. Really nice, but doesn't have driver's assist cameras and had the metal roof with a sunroof. I'd prefer the CF roof. But the car was in immaculate condition. Full Merino leather, DCT, HUD... so tempting, but not exactly what I wanted. It did have fresh MPSS though :-)

Oddly, all of my tires are late 2017 Manufactured date, Except one of the rears is a mid 2016 MFR date (Not a typo). I was a little put off by that as well. I didn't know they made these tires TWO years ago. Does tire rack not rotate their stock?

I'm sure they do, but weird situations come up all the time, like a person buying a single tire due to a flat or whatever. Some sizes are also less popular so they tend to sit around. TR can try to anticipate this but sometimes they guess wrong.
