Who has run both?
Which is faster?
How long did each last?
What sizes did you run?

Thanks

Howie...just curious, but why are you even considering the PS2 when you can get the PSS....?

If I wasn't in the Corvette Challenge you are right I wouldn't even consider them, especially as they are more $$$$

But if I run the PSS then I will be bumped up in CLASS and have to run against the boys with R6 tires.

As it is I am running against someone with ported heads/tune and PS2 on 19/20 stock wheels. I'm not even sure if that setup is an even bigger advantage that 18/19 ........ didn't check contact patch size ....... but assume is good if on Z07 and ZR1

My only mod is DRM Bilstiens ..........

Dirty Howie

See above ......... there is a reason.

I have heard some say the PS2 is actually a better track tire than the NT05. If so and with more HP and a younger driver I am in trouble !!

That's why I don't race in classes... Too many crazy rules.

Well...IMO. You'd be better off with the NT05s especially for the money.

Dirty Howie

Well I just got a pair of 295x35x18 that I'm hoping will let me carry more speed without pushing in sweepers as well as better braking with larger contact patch.

Did you buy PS2 or NT05?

JetBlue427

are you positive your not confusing the Michelin Sport Cup tire with the Super Sport tire in that particular class?

roadandtrack

I have $100 that says the Z06-spec Mich PS2 ZP would win!

A Michelin engineer told me that the PS2 ZP would almost certainly lap faster than a Pilot Super Sport.

JetBlue427

huh? the PS2 ZP faster then a Supersport? I think you misunderstood that conversation especially against a non ZP tire with a better handling and braking rating (straight from there marketing dept)

Howie, the NT-05 has a 200 tread wear rating, the M PS2 has a 220 and the PSS has a 300 wear rating, so it won't bump you up in class over the NT-05.

The M Pilot Sport Cup is an R-compound track/street tire with an 80 wear rating and it would bump you up.

The PSS with a 300 wear rating has more grip than either the NT-05 (200) or the PS2 (220). That is because of its newer high tech design, construction and materials.

I didn't misunderstand and I have it all in writing from a Michelin engineer. I was as surprised as are you by his statement! Keep in mind that the PSS in our stock sizes is a generic tire (and my current favourite street tire BTW!) while the PS2 ZP in the Z06 sizes was engineered and tuned specifically for one chassis.

I would have to agree with this. Not sure why this is the case but the ZP's are amazing when temps are up. 14 year TWS instructor that rode along thought I was on R6's.

Running PS2 ZP's front/rear mounted on 19" HRE P40S's.

I have run both had mp in front nitto in rear with great results...

AzDave47

I find it interesting that M would super engineer the PSS as successor to the PS2 and have it have lower performance.

From the tire test M invited me to 13 months ago, I got the strong impression from their engineers and designers present that each new tire the bring out will be superior in performance to both their competitors' tires and their own tires. In fact at the tire test that was what they were having us confirm. We were even comparing their performance all-season tire to competitors' summer only performance tires, with very good results.

Dirty Howie

I got NT05 as I have 2 sets of rears NT05 and didn't want to run different tires front and back.


DH

Dirty Howie

Nope. I'm absolutely 100% positive.


DH

Dirty Howie

I'm talking about the PS2 non run flat. So I assume that would do even better than the ZP version. Do you still have access to this engineer?
