Thanks Dean. I actually have 2 sets of slicks ready to go but can't get these damn Nitto's to finish their life cycle. Damn them for being so great

tkerrmd

I just ordered a set. I thought these were "R" compound tires? So I would not have compared them to a "street" tire? I was going to try to use them to replace my cup tires cause I cant find any, is this a better comparison than PS2's? Dell??

Will they be near the performance of my hoosiers??

LVDell

Tom, they are R comps.

The order of lap times all things being equal except tires (driver, car, etc.) and the tires being on their "fastest" and "grippiest" lap.

All are R-comps (each tire is probably 1-1.5 sec faster than the next on a typical 2min circuit)
1. R6
2. MPSC
3. NT01

Now if we look at longevity and bang for the buck
1. NT01 (40-50 HC's and best toward the end)
2. R6 (20-30 HC's)
3. MPSC (about 16 HC's and they are done)

Dell,

You should be able to finish them off at Kershaw no problem.

Looking forward to it

I'll have a backup setup in the trailer just in case.

That's interesting Dell. While I agree that tahe R6s are quicker than the MPSCs. I tend to get only a touch over 20 HCs out of the R6s and the last time I ran MPSCs I got 43 or so HCs. I found the MPSCs lasted longer than the R6s. They did suffer a drop off in performance after 20 HCs and were like plastic when I finally chucked them, but I got significantly more life out of them than the R6s. I don't know anything about the Nittos. I'm trying the R888s right now. Mind you my car is just a 99 996 C2 but it can get around VIR in under 2:13s.

Interesting. Good data point KJ. I have heard way more testimonials the other way around (as I reported) but I have no doubt you experienced that.

The main point I was trying to drive home is that the R6 and MPSC are definitely the faster tire over the NT01 but not by a huge margin. Because of that and the longevity I find the NT01 to be a great bang for the buck R-comp.

I'd like to hear about your thoughts on the R888's.

I'm running 305/35/18, 245/40/18 R888s. While they are no hoosier, I think they perform excellent. I got about 35 HC until they were toast. Tire had great feedback and nice slip angle. Turn in wasn't that precise, but once use to, it was ok. I think that had more to do with increasing the sidewall ratio from 30-35 in the rear and 35-40 in the front. I will say this, by increasing the sidewall they are downright scary at high speed. Anything over 120mph and the car became unstable and braking was practically a sphincter moment everytime. Last weekend I had to brake 150ft earlier than the hoosiers just to feel safe. Buying a set of 315/30, 255/35 R888s tomorrow. That should fix the problem.

LVDell

Ryan, I talk to you at the next event to get your impressions of the new size. Are you going to be at the Fall Fling?

rmag

Didn't sign up in time ... groups are full. Next event at VIR is probably NNJR Nov 10th (although got 3 Summit Point events dialed in before that)

LVDell

Fall Fling will be my last until the 2 events in Dec I am doing at VIR (Chin and Carolinas PCA). NNJR falls on the week the baby is due.

multi21

DId you get to the cords at the 35 HC point or was there tread still left on the tire?

davidf1

And I thought I was going to have to purchase another set of 01's next year but after seeing Dell's post I'm sure I'll be fine for all of next season! Question, I swap mine left to right without dismounting from the rims. Any pro's and con's as to which way is best?

david

LVDell

As long as you are not burning up the outside of the tire b/c of camber issues then just putting left side on right and vice versa after every event should do the trick just nicely. However, if you are camber challenged you will want to flip the tires on the rim.

What do you consider a heat cycle? Is it 1 HC per each 30 min session (4 in a typical DE day), or 1 HC per day of multiple track sessions, or ?
