My C4S is going to need new tires soon and I need something stickier than stock P Zero.
I was thinking between Michelin Sport Cup 2 or Dunlop Sport Maxx Race.
Both are Streetable & Track Competition tires. Any suggestion?

 

Michelin PSC2 should be more streetable. They at least have a better wear rating (180 vs 80).
Are you using them for track?

 

For DD but I need something better than stock tires.

 

For the street I would go with Pilot super sports all day long. I've had a set of the sport maxx race that I used on the street and track, but they didn't last too long. The grip on the SS in not that much different, but they are almost half the price and last twice as long.

 

Saying that either of those tires is "streetable" is a pretty big overstatement.

They only way I would street drive either of those tires is if I lived somewhere that it absolutely never rained. Get caught in the rain and you'll definitely regret having them on the car. Take my word for it...

 

Squires, I totally respect someone being man enough to drive track tires on the street.
But then I also wonder what part of the handling on stock tires is not good enough for you?

Stock tires handle amazingly well, if tire pressures and alignment settings are right.
I upsized my front tires, reduced rear camber, increased toe-in, and reduced tire pressure.
It seemed to address my concerns, to the point that I dont think I "need" track tires and I kind of enjoy seeing how hard the car can be pushed on street tires.

What part of the handling on street tires was letting you down?
Are you running your tire pressures too high?

 

Both tires came with the new GT3 so you mean GT3 will have problem in the rain?

 

Well I had the pleasure of getting caught in the rain with our GT3 several times and let's just say I was REALLY nervous about how the PSC2 handled the wet. Traction in the rain was terrible in my opinion.

If you're looking for a good track/street tire with plenty of grip, I'd try the Pilot Super Sport before I took the chance with either of these.

 

I run stock tires at DEs. Pressures seem good (40psi hot). The tires are great but start to chunking after 5-6 days of pounding. Porsche mech thought GT3 tire might be a better choice. Still debating because I use it everyday and am too lazy to switch out tire for track day.

What are you doing that they are not chunking? What are your hot pressure?

No question that track tires are better for DE.
However, I also am done with wheel swapping.

I dont seem to have chunkinking problems, but I am carefull about where I run.
Some track surfaces eat tires more than others.
My hot pressures are 40lb.
My outsude tire wear was so good, I took a bit of rear camber out.

The problem I previously had was tires greasing up badly.
Since the alignment adjustments, I have not had that issue reoccour, but weather was cooler also. Regardless there was improvement, but I know they will still eventually grease with enough laps.

Also, all this is on PSS, so not the stock tires. Since PSS are harder, they could be more reistant to chunking. Overall they wear very well.

 

MSC2 tires are standard on the new Z06. They looked like track tires on the outside tread. I was wondering how they would be in the rain. Not good I guess.

 

I too am considering tires and will likely go with Michelin pilot super sports. Any idea how many mikes I can get out of them?

 

I love my PSS's, but asking how much milage is like asking how long is a piece of string. Depends how you drive, care for them, DE events, etc., etc..

 

MPSC2's are a hybrid track tire with minimal rain grooves and a track compound. Half a step towards a street tire from a race slick...so while you CAN drive in the rain, wet grip is severely compromised in cornering or in standing water. It basically allows you to drive carefully to the track and home and through some mildly wet weather, or drive vigorously on the road in dry conditions. Toyo R888's, Hankook RS3's, Dunlop Sport Maxx, Conti's Force Contacts are all in the same category. They will wear really fast on the road if driven briskly - 7-10K miles or less for sure, especially on the rears. This compared to a proper sporty road tire which should be good for twice that.

I agree with the poster saying what is wrong with a classic, high performance street tire for road driving?... the tried and true MPSS being the prime example. Or Dunlop Star Specs are another (now called Direzza Star Specs), Bridgestones 050's, Conti Sport Contacts, Pirelli P Zero's...these are what we should be using in non-snow-condition road driving wet or dry...they are made specifically to be a serious sport tire for road driving. Sticky rubber (short of R compounds), full rain grooves, stiff sidewalls for feel and firmness through corners and hard braking...

 

Car is a dd but drive a short distance to work and back. No track use.
