Period. End of story. If one single person by chance does pop their head up and claim they have a set on their street car, I would ask them to post a picture of the sidewall- it won't have a DOT approval...

Now go purchase and enjoy a tasty set of "regular" Trofeos. And hot pressures should never be higher than 31psi front or rear 29 psi is optimal...unless you want to eat them up in one track day or enjoy drifting or both.

"TECHNICAL ADVICE
The right pressure for racetrack driving

P Zero™ Trofeo has a quite stiff construction and does not usually require higher pressures for racetrack use. It is designed for use at a pressure of approximately 2 bar, to be adjusted according to the type of car.

The figures indicated refer to the “operating pressure”: the pressure of the tire when it is fully warmed up to working temperature. For accurate calibration, it is essential to consider that the difference in temperature between a “cold” tyre and a “hot” one is quite significant, normally 0.5 bar.

Thanks Pete I have a new set of the Trofeos (not the new ones) ready to install....just need a set of wheels....

It was bad in the wet. More close calls than I want when I am driving conservatively.

When I had my 2004 996 GT3 on MPS2's, I was driving 60km/hr on the #1 Hwy to the local track in miserable conditions. I drove to the local track last year with my 997.2 GT3 on RE11's and looked down to 125km/hr in comparable conditions. Just amazed!

Testament to the improvements in the car & tires.

Yeah, I just didn't get around to refilling the tires after the event and drove home about 90 miles on them at cold track temps. Then I drove it to work once or twice after that w/o refilling. I have -2.25 camber in the rears and the inner part of the tread was basically down to the wear bars.

Sounds like I might have to give the original Trofeo's a shot. It'll be good to compare them to the new compound whenever it is available. Thanks for the responses.

Northshore04, thanks for starting this thread, as I too am thinking about tires.
I haven't seen anyone selling the Trofeos yet but have been happy with my MPSC (in the dry), however they wear quickly.

For a good road tire with occasional tracking what is the consensus on:
Bridgestone RE11, Yokohama ADVAN Neova AD08 & the Michelin super sport or any other tire.
I'd like good grip on the track with a longer lasting tire than the MPSC.

I've heard people who are fans of all of the above. Then again, each has its detractors too. So basically, there's no one magical tire out there that will please everyone. It's funny but I was just mentioning to someone that one of the great things about the track is trying different things and seeing which works best for you.

Personally, I think I'm going to give the MPSS and the Trofeos (both old and eventually new version) a shot next. The search for THE track/street tire continues. . .

There is no free lunch. The Trofeo is a much stickier tire, but the downside is much faster wear. For track use, the MPSS is not even close to the Trofeo, with the Trofeo being 3+ seconds faster in a 2 minute lap.

Nan, Trofeo's are what I had on when we were at ORP.

Pressures are definitely key for these tires. You must adjust pressures and watch wear on the tires. Even though they recommend 29psi hot I had to use a bit more in the front to stop the outside shoulder from cording (-2.8 fr camber). 29 hot in the rear was perfect with -2.4 camber.

Funny my first time out on MPSC's after the trofeos I was quite surprised how much less grip I had (mostly in the rear). Felt more balanced though.

I'm anxious to try the R's.

So, are the regular trofeo's updated now with a new compound or is it just they have an R version out?

Here in Asia we've had Trofeos for over a year. They are very grippy for a street tire. Definitely faster than N1/N2 Cup+ to the tunes of 0.5-1 sec on a 2 minute lap. Whereas MPSCs will degrade linearly beyond 10HCs and will have rubber to spare for many more HCs, Trofeos will be long corded before the 10th HC. They are 80-90% as good as Hoosier R6's while the rubber lasts, but the compound is real soft and not designed to last, particularly in hotter climates.

I've driven a set myself and will ABSOLUTELY choose Trofeos over MPSCs if faced with the choice (despite the price difference) out of better dry grip and *marginally* better wet safety. The only problem is I've never seen a set of Trofeos last more than a full-bore track weekend here. Not for anyone driving more than 6/10ths on a decent DE car anyway.

p.s. the Trofeo sidewalls are softer than MPSCs so you'll likely see better ride quality if street driving's part of the plan. Just don't expect any mileage from 60 [or is it 80?] treadwear rubber...

This is why we're all waiting for the Trofeo R's....

Which is real interesting... from the looks of the marketing schpiel most everyone should be buying the new R's instead of the current product...

CRex, Pirelli, claims the Trofeo is a very stiff tire and need very low HOT pressures. To me that would mean you could run a little less camber...like -2.5f and -2r....which is what I'm running on my MPSC and wear and temps are about right...I could use a touch more negitive camber. When I ran Toyo R888 this amount of camber was a touch too much and something around -2.3 front and -1.7 rear would work better on a flat track like Sebring.

I want to try out Trofeo's, but your reports scare me....I don't want to waste a set of Trofeo's at Sebring in 1 day or weekend.
