Corsa TW-60
PS2 TW-220
Corsa are 100% better than PS2,they wear faster but the grip of this Pirellis is really amazing.

Like Mr.**** said you downgraded the tires.

 

I went from the MIchelin Pilot SPort Cups after 2 sets and feeling them get greasy quickly (once they hit the sweet spot it's bye-bye baby, they deterioate quickly. I got turned on to the R888s GREAT TRACK tire & street tire..... always checking psi and keeping them "warm", and finally purchased track wheels (18inch with the proper offsets for my brake package w/Hoosiers on them). I had run a car with Hoosiers and loved how those felt as well. But of course can't drive them on the street.

Some people like the MIchelins, I personally dont. I think you would love the R888s. that's my 3 cents worth ;-)

 

+1

 

Thanks for all the advice on the tires. I can only assume they'll get better once they scrub in because I've run lesser tires on sedans that feel and respond better. If they still $uck, I'll pull them and save them for rainy season.

Question though .... you really can't get temps into tires on the street so it stands to reason that a street tire may perform better on the street than a track tire since they are optimzied to perform better at lower temps. This was my thinking anyway. Flawed logic? Or is an R-compound tire going to still out perform a hi-perf street tire like the PS2 even when cold. My experience tells me not, but if it's true that the Corsa is a somewhere in between for good cold temp grip, then that changes things.

Also, for folks thinking about PS2s, take note of this thread. Virtually, every thread I've seen has folks raving about how great the PS2s are so they seemed like a no-brainer, then I get them, don't like them (so far), and then all the gremlins come out of the woodwork talking about what a downgrade they are etc. Perhaps I'll go back to the Corsas since I liked them. I'm tempted to get the 888s like everybody is suggesting here but then I'll probably have to listen to everybody tell me how much they $uck as soon as I have them mounted. Tires aren't cheap and I know and like the Corsas.

 

It's an unfair comparison though ;-) If you want to compare the Pirelli Corsa's, you should rate them against Michelin Pilot Cups.

People rave about the PS2's as a fantastic max performance tire and not R-compound tire.

 

Right

 

That's a fair statement I'm looking forward to them getting better as they scrub in. Right not they're nothing to brag about ... R-compound tire or not.

 

I went from PS2s to PScups on my 997. The cups have a way better feel. PS2 tires are great. but i love the cups. ( thanks Paul )

 

I can tell the MPSCups are better than the PS2's but its a compromise. Less performance for lasting more than twice as long. I remember the first time I took out my GT3 in a canyon and how more grippy they felt than the PS2. But I also remember the first time I got the bill after replacing the rear Cups at $1100 for Two tires. But now that I have moved to 18" rims I might go back to Cups or the R888

 

Does anyone know the recommended tire pressure for Nitto NT-01's for standard Gt2 tires (235, 315, 18's)? I am running 35 front, 40 rear tire pressure (cold). The steering in the front feels a little light. Could that be too much air pressure, alignment?

 

i seriously doubt one can feel that much difference b/n ps2, mpsc and corsa on street. if you do, you have way exceeded the speed limit.

on track, corse and mpsc are both better than ps2.

r888 is great, i have gone through 6 sets or was it 8 sets? but i would take RA1 over those anyday. for 997 you want RA1 in 245 and 305, R888 in 255/315 with 12" rears.

 

Tread Wear is only relavant when comparing tires from the same manufacturer, there is no standard that determines a standard wearing tire from brand to brand.

 

That's too high for a r-compound tire. I drop it by 3-5psi cold.

 

Threat ware determination is made by the department of transportation so it has nothing to do with brands.
And from th 60 to th 220 there is a big big difference.

 

NorthVan is correct.

Brand X treadwear rating of 200 can be completely different than brand Y's tire rated at 200.

Within the *same brand* comparing a 60 to a 220 would be relevant.
