I am thinking about getting a new pair of summer tires for my 968. As I only drive about 3,000 miles a year I won't mind if I only get 20,000 miles out of a set. I use my car as a daily driver with an occasional auto cross.



so. which tire is the most sticky?

For autocross, I am a very big fan of the Dunlop Direzza Z1 / ZII Star Specs (200 treadwear). That's what most of the guys I run with use, on all varieties of cars. I am still on a set of the previous generation Direzza Z1's. They are a very sticky, but most importantly are very predictable when they're letting loose. They are also a great tire for the street.



If you want SUPER sticky, a set of Michelin Pilot Sport Cups will fit the bill, but they price out nearly 2.5x the cost of the Direzzas, and may bump you into an improved class as their tread rating is only 80 - here in the US, running with PCA you can go as low as 180 treadwear in stock classes.



The Bridgestone Potenza RE-11A are also highly recommended for autocross, but I haven't had experience with them - only one or two guys running them at our local track so far.

I just put on Bridgestone RE-11's from tire rack. Great deal now since the RE-11a is out. I autocroossed today at Sebring, and 2 weeks ago,at an airport. Imhave a DE in 3 weeks at Sebring, cant wait. I prefer these over the yokohama AD08. Better in the rain, and dont require warm up. Very stiff sidewall. Hankook RS3-is great value as well.



You will need to replace after 3+ years regardless of mileage, they get hard.



Good luck.

The BF Goodrich G-Force Rival has been getting phenomenal reviews lately - it's finished first in every tire test I've seen it in so far, and it's pretty affordable.

Completely agree. I don't think there is anything out there as sticky as these tires, other than Hoosiers slicks . HOWEVER, at about 60 MPH ( and this is not when they start wearing out, I'm talking about them while still new..) they start howling pretty badly. At 70 - 80 + mph they are so loud, they will drown your stereo and you'll feel as if you need earplugs to tolerate driving your car. I turned them back in one week after I bought them. But a heck of a fun week when I was not on the highway, whipping the car into sharp turns at stupid speeds without the slightest slip or slide. Jaw dropping grip.

Are your freeways all concrete up there? They were definitely loud when I lived in Socal on the concrete freeways, but on asphalt I have no issues with the noise. Then again, all tires seemed to be loud on the concrete...

I think most ( if not all..) are concrete . However, on the very same roads none of the other tires I've had have been noisy like the Direzzas . I was wondering if the set I got might have been defective but when I returned them to the tire shop ( America's Tire ) and just started to say : " I got these last week, and..." before I even had a chance to continue, the rep asked " too much noise, right ? ". So they're all like that but if on asphalt they ride quietly, it s certainly a great tire which sticks like superglue !

Interesting, I have them on the white 968 and they're fine.

So it begs the question : Asphalt or Concrete highways in Pa ?

We don't do concrete highways in the Northeast...they're more dangerous in poor weather conditions, and the way they treat the roads out here with snowplows...they would be replacing the roads every 5 years anyway like they do with the asphalt - except asphalt is a lot easier and cheaper to patch or replace. Concrete being smoother, it does give you a little better gas mileage - but your tires don't stick as well to it as they would asphalt.



There's one spot at the airfield where we do autocross that has a big patch of painted concrete (the rest is asphalt) and it's always fun to watch the 911s hit cones sliding out there, especially in the rain.

dunlops have always been notorious for being noisy. every manufacturer has a philosophy on how they build tires. historically dunlops have been noisy and stiff, but long wearing and grippy

My RE-11 Bridgestones are much quieter than the Yoko AD08. No experience with Dunlops is 15 years.

What is the opinion on Perellis? I had them on my 924. I think they were the P2's. Can not remember back that far as that was 1979.
