Nitto NT 01 - R Track tire
Has anybody tried these track tires?
I have run Sport Cups in the past but I don't like how long it take's them to come to temp. We live in a cooler climate.

I found this on another forum, true or not I don't know, some people I have spoke to doubt it.
this was on a 03 Z06
Here is plain facts for several tracks I run and comparative times (many same weekend and swapped to compare)
RA1's were unshaved as were PSC. Each pick up about .5-1 second when lower tread or shaved.
Roebling Road 1:18.4 (Hoosiers) 1:21.3 (NT-01's) 1:22.5 (ra1's) 1:23.2 (PSC)
VIR Full 2:06 (H) 2:11 (NT) 2:12.8 (RA) 2:14.1 (PSC)
Several of these are multiple times and an average of best 5 lap times.
For my suspension set-up the Hoosiers were to much tire and would be quicker with a better set-up.
Nitto's are new compound (same company as Toyo by the way) and they wore well. They also work in any head range and don't loose much when they get cookin hot either. Starting with less tread though may only get 15-20 sessions out of them.
RA1's - best predictable tire of any of these. Can last 35 sessions and drive to events.
PSC's - suck in cold. Unless it is hot they will be scary slick and basically like driving on ice. And hot I mean at least 75 degrees and up. they like lots of camber. Now once really hot they wear like iron and stick great. But the cost makes them a I will never buy again item. Other choices are just better and work in cold and hot and are quicker.
Hope that helps folks.
The above times are over literally 3 sessions minimal on each (slicks) and more than

It looks like the tire sizes are pretty limited at this point.

The problem as I see it with all these comparisons is that to perform the test properly, it would be a big undertaking. First, to be fair, the car needs to be setup for each tire. Then the conditions would have to be consistent. Then for us, the car used would have to be similar to ours. There are just too many variables. (and I'm sure I left out quite a few).

I just put on a set of these after cording my RA-1's a few weeks ago in Hastings.
Put them on Thursday afternoon - drove ~150 miles from Ft Collins to Pueblo for their first heat cycle. The tires were not shaved and had not ben heat cycled - I was in a hurry to make an open track day at Pueblo Motorsports Park.
Impressions: A litle squirmy at first, but I guess that is to be expected with their full tread depth. I managed to put on about 150 track miles on them today so I got them past the squirmy, new stage. They feel a bit more "numb" than the RA-1's or PSC's but my lap times were right whre they had been with those tires. In fact they might have been a little easier to drive fast than the other two. I set the pressures at 29r/30f cold. They stayed pretty good so I never felt the need to check them again (nor did I manage to pull myself away from the fun long enough to put a pyrometer on them). They were pretty noisy on the way home but I'll be trailering them to the next event so that's not a concern. Would I buy them again? If they stay a bit cheaper than the RA-1's I think so.

I was speaking with another club racer at Cal Speedway about the tire choices out there for my GT3 once the PS2's wear out and he mentioned the Nitto's were worth looking into. Unfortunately, the tire sizes are somewhat limited for the rear.
I'm in a quandry as I've had the MPSC's before and don't like their chariteristics, but it's the only tires that have OEM sizes on the GT3. I'd go with the RA-1's as I drive to the track, but sizes are either too big or small for the rears. Anyone put on 305's in the rear without rolling the fenders?
