Anybody Here Have Experience with Both Michelin Sport Cup 2 and Pilot Sport 4S?
 

I have ran Sport Cup 2's on my 997 turbo as well as my AMG GTS. The cup 2's are great but they need heat to hook up and are expensive. How do the PS4S hook up with the GTS?

I have Pilot Sport 4s on a 19/20-inch set of wheels and 20/21-inch set of wheels for my GTS. Like them a lot, feel you would enjoy as well if looking for something a little “friendlier” for daily activity vs the Sport Cup 2.

If you mash the gas in second gear on a 50 degree day, do they break loose? My cup 2's break loose without heat but maybe the 4S will hook better under cooler temperatures.

Why are you doing that? Surely the answer you're looking for is to drive properly?

Anyway P4S has better wet/cold weather performance and Cup2 performs better in the dry. I'd only consider the Cup2 if you do some track driving or if you only drive in the dry.

By breaking loose of you mean loose a bit of traction? With the 295 width rears set sure, a bit.
with the 325 width set not so much.

Now that assumes I’ve put some heat in them by driving a while vs. just pulling out of the garage on a 50-degree morning when it sat overnight with temps in the 30’s or 40’s.

Again, the 4s is an INCREDIBLE street tire, if you want better warm / dry only traction, you have a great tire already.

My cars see mostly street but I do 2-3 track events per summer.

And I ask about mashing the gas in 2nd gear because I want to know my tires can handle that without any issues. Not because I do this every time in 2nd gear but more so to know the tires are an adequate match for the car's power. An under-tired car isn't always safe and like many people here, I do step on it once in awhile.

I'm not sure why you can't wait for your tyres to warm up then?

When my OEM SC2s are worn enough to replace I’d love to get a set of PS4s for my GT R IF they are made in the correct sizing.

I have a dedicated set of wheels and tyres for the track and use the ‘option’ GT R tyres which is the MSC2 ZP. So much better on track than the OEM SC2s.

It's not just the tires that need heat. If the tires are warm and the pavement is still cold, there will still be wheelspin with race compound tires. The compound on the PSS and PS4S are better equipped for the cold pavements.

Will love to hear your opinion on the 4S in contrast to the SC2.

Bet the GT R rips on a track with the SC2 ZP!

I’ve mentioned it before in other threads, but I felt that the car was ‘under tyred’, especially in the front on the OEM SC2s regardless of what PSI I started at. The wider and ‘stickier’ SC2 ZPs really helped understeer and of course made the car quicker on a road course, at least 2 seconds on my local track. But given they are a RFT the compliance on the street is poor especially if you have crappy roads, and the wet handling is marginal.

I just ordered a set of PS4S for my GTR to put on the stock rims for DD. I have a 1500km round trip coming up and I am taking the GTR.
I strongly considered a set of Michelin AS3+ ZP as they can be had in a 335/285 combo and I was thinking of using them for a wet track tire too.

Ordered PS4S 325/25 & 275/35. Would have been nice if there was a 335/285 combo but there isn't yet.
The 325/25 & 275/35 has a closer matched sidewall profile of 26.5".
Where as, the OE 325/35 is 1.2" taller.

I have the 335/285 CUP2 ZP's on a set of rims for the track.

The new A/S 3 ZP is getting really good comments on the Corvette forum as a three season tyre on the Z06/ZR1 platform; great handling even in cool temps and excellent in the rain with a good ride. Personally I think it would be a great DD tyre for the GT R, although being an RFT I would be a little concerned about compliance. Great wet weather track tyre as you mentioned though.

My OEM PSC2s only have around 3,000 miles on them but the car seems to ride a little ‘rougher’ now that it has been taken out of its winter storage. I had stored it with around 40 psi in the tyres, but even in the garage the temps were super low at times so I’m kind of wondering if the tyres were compromised somewhat. Hell, I’m really just tying to talk my way into buying a set of the PS4S’! lol

I like the PS4S. I got about 6,000 miles on my Conti 6 from the factory for my GTC. The 4S are a bit better in cornering. There is a certain onramp in my area that I have been using for a testing skidpad for tires on exit speed. And my max speed went from 54 in my GTS with PS4 to 56 in the GTC with the factory Contis to a max of 58 with the PS4S.

FRIG.
I probably should have got the A/S 3 ZP. I will be in the mountains and the ZP would have added a bit more security and peace of mind. Will have to take a few cans of fix-a-flat.
Anyways, I have been bombing around for the last 2 weeks on the CUP 2 ZPs, and they are hella loud. Have two track days on them and nearly zero tread left (not that there is much to start with).

The MPSC2 ZPs are hella loud on the street as you mention. Try starting at a psi no higher than 28 F&R and see if that helps; it will certainly help with compliance. As you are well aware, be careful in cool weather as the ZPs don't like ambient temps below 10dC/50dF and never run them in the rain.

I just brought my car to the dealership for its B service and a fresh set of front Cup 2's. So I pick the car up and take it for a drive, things feel a little weird as I go down the highway.
I get to the gas station before heading up into the canyons and noticed that the dealership installed a pair of Super Sports instead of the Cup 2's..
Huge difference between the Super Sports and the Cup 2's.... No questions asked as the dealership replaced the Super Sports with the proper Cup 2's at a discount ..

The Super Sports are actually a great tyre and at all four corners would suit the car well. Not SC2 well, but pretty darn close, and better in the wet.

Mixing tyres is of course a no-no. Glad your dealership took care of you.

What a blunder by the dealership! Glad they made it right.

Depends on how you use your car. If you only use it for good weather aggressive driving and dont mind changing every 4-5k miles, the Cups are much stickier than any street tire.

PS4S is the best true street tire out there if you use your car primarily as a means of transportation.

Yup, I run the P4S on my E63s wagon and the Cup2's on my GTS..

I definitely use it for the former... 3,000-3,300 miles per year. Good weather only, aggressive backroad driving.

Are there PS4S sizes available for GTR? I checked tirerack and other sellers website but found nothing. Others in Asia and Europe say they can get PS4S & some continental tires which are more usable for daily use.

335 CUP 2 ZP (Left) / 325 CUP 2 OEM (Right)
Side by side the difference is substantial. ZP less tread and less tread depth.
Cup 2 ZP measures 13.875" vs Cup 2 OEM 13.25"

OEM CUP 2 is about 1" Taller than ZP
335/285 combo is near perfect sidewall ratio. OEM Sidewall ratio is about 0.5" difference

335 CUP 2 ZP (Left) / 325 PS4S (Right)
ZP measure about 13 875" and PS4S measures about 13.5" across width. ZP is a hair taller.https://cimg7.ibsrv.net/gimg/www.mbw...92027a2b99.jpg
