Try calling local tire shops, I'm in the bay area in CA and I was able to get one from a local shop - he told me at least a couple of his suppliers had this in stock.

Can't comment on 255/275 vs 265/285 Michelin 4S tires, but I can say that my 255/275 Continentals pretty much sucked compared to my current 265/285 4S setup - always breaking loose especially in the wet. Now car hooks up pretty good. Very noticeable difference on the track as well.

Edit: current setup is 265/285 not 265/295

Dang you are lucky. I guess I will try making some more calls locally in my area

I gave up and ordered a Cup2 set today.

I have the 437 as well and have the same question.

Wondering if I should go with either the Oem size on the PS4S (255/275) or if I should upsize to (265/285). Have been reading that the 265 is squared off instead of rounded and not really meant to be run as a front tire. I don't really care about the looks, but if it's meant to be a rear tire would think that it's not going to handle as well. Would welcome any thoughts.

Also how is steering feel impacted by going from the 255 to a 265?

Why not go with a 255/285 setup?

I don't really have issues with rear grip and would like to try and keep the same ratio as stock so am thinking either 255/275 or 265/285

Well if you are happy with the level of grip from the oem 255/275 setup then I would just stick with that. If it ain't broke don't fix it.

Was reading that the PS4s like for like sizes are narrower than the PSS so that was why I was thinking of sizing up.

Well you're not going to find any 285 profile in 19.

I had to go with stock sizes

I can wait it out, not super urgent yet. Just want to make sure am getting the right setup. If everyone is running the 265 up front then I will certainly give it a shot.

@michaelalex17 , I am running 265/285R19 on stock 437m mags. You can see my pics few pages up. To be honest, for day to day driving, I can't feel any difference except the 4S are a tad more comfortable compared to the PSS. I haven't pushed the car with those tires this season as temps are still cool but I think if you want the widest config that is as close to the OEM setup without any modification, that is the recommended config in here.

I like the grip with the 285, the 255/275PSS IMHO were not a proper match for this car's power/torque.

Thanks, appreciate the feedback! Has anyone pushed the 265 up front? Not from a grip perspective, but from a steering feel perspective how does it feel? Heavier and more numb then 255? Or not noticeable?

You might be waiting a while then. 2000 on back order and Michelin isn't sure when they're starting production again.

I got a local tire guy that usually has the hookup. But either way I just want to figure out which route to go with. Is the 255 Ps4s narrower then the star spec 255 PSS?

[rborane]

Look at the specs for each on tire rack. From what I remember, PS4S run wider than PSS (Star spec and general spec)...

You are partially right just checked. PS4S is wider than star spec, but not generic

255/275

Tread width
PS4S
F: 8.9
R: 9.8

Tread width
PSS star spec
F: 8.6
R: 9.6

Tread width
PSS genaric
F: 9.2
R: 10

265/285

Tread width
PS4S
F: 9.6
R: 10


So, I'm not really sure how this all works, but the difference in tread width between all of the 255/275 setups is about 0.9 front to back whereas the 265/285 setup is 0.4 difference front to back. Not sure if that matters but would think that having a setup that is closer to being a squared setup would impact handling

Love this thread and all the previous ones related to it. Thank you to everyone for their feedback, pictures and willingness to help one another. Hope these tires get stock'd up for the summer!

Indeed! I've been driving a bit more in hotter climate, and I must say the PS4S 265/285 (or any brand new tires) are fun in straight line accelerations w DSC off (only aspect I played with in remote secluded areas). I finally settled on 35psi all around, some folks in another thread recommended much higher for those tires. (40psi+)

Just wanted to give a quick thank you to CanAutM3 for his advice

Ended up purchasing new PSS in 265/35/19(M0) & 295/35/19(Star). I know the PS4S is superior overall but given the narrower tread width on the PS4S 295 and a couple other small factors I decided to stick with PSS.

Couple pics attached since I know it helped me seeing other peoples setup before making a decision. I'm lowered on Macht Schnell springs (website says lowers by 1.1" front and 0.75" rear) with no spacers.

Can't say for certain no rubbing since I've only driven home from the tire shop but I think i'll be fine. For sure it was a more comfortable ride than my previous 275/30 and 295/30, that little extra sidewall helps alot more than I expected.

That looks amazing. What are your wheel specs and offset? What tires were you running before? Nice work

Thanks man! They are HRE flow form ff01, 19X9 +25 and 19X10 +40 (I think).

I had 275/30 and 295/30 before. I wanted a slightly less wide tire up front this time, and to keep the front/rear ratio in a good spot I had to increase to a 35 sidewall. My previous tires had a more square and sporty look but I'm still happy with the look and it'll be a better setup.

Just curious but has anyone gone 265 fr 275 rr with the MP4S?

I'm only asking because I'm dropped on the MPerf kit and 10mm spacers. Because the 285's are on crazy backorder and the 295's will likely rub with my current setup, I'm wondering if this would be a better alternative than the 265 fr 285 rr setup with the standard star spec PSS's.

[///Mongo]

I had Michelin PS 4S tires installed on my stock 437M rims today

Front 265/35/19
Rear 285/35/19

The grip is absolutely astounding. I am coming off the stock Continentals (which amazingly lasted for 25k miles despite several track days) and the difference is night and day. Highly recommended.

Thanks to everyone for all the great info in this thread
