Agreed. I always heard the RA-1 and NT-01 were the same compound. Would explain the similar consistency. The R888's fall off a cliff after about 3/4 of there life.

I was under that impression as well but heard r888=nt01 under good authority. Or maybe they're all the same lol.

Always heard the compound sof the RA1 and NT01 are the same. They certainly behave very similarly, with their only real distinctions being down to tread pattern/depth (hence the unshaven heat buildup in the RA1s, and their advantage in the rain). But their grip level, heat cycling characteristics, etc. are almost exactly the same.

That's not true with the R888 compared to the NT01. No way are they made from the same compound IMHO.

Agree. The R888s I had are/were distinctly different than the NT01s.

considering some r6's... this is for the track, not autoX or drag. i was told that a 255.35.18 in a r6 would be 10mm wider than a dunlop star spec 255.35.18?? (which is what i have..)

No complants this far. Had them heat cycled when I purchased them from Tirerack. They have lasted the whole season and have some tread left.

Yeah I use either Hoosier R6 or a Goodyear Eagle RS (road race compound). 245x40x17

The Hoosiers will heat cycle out before they cord... prob loose 1-1.2 seconds after about 6-8 heat cycles. Goodyears hold up a bit better... wear is nicer and sidewalls are stiffer (which I like) but if you're not going for tenths I wouldn't worry about the heat cycles.

I just picked up some R1R, 275/40R17 to run on my GR. I have to run a wet/dry tire here in Oregon since the track days I hit are early fall and spring which means high possibility of being wet. I can post up a review since I will be heading out on them Oct. 21st. Hopefully they are not as squirmy as described above!

6-8 heat cycles on the r6's? Is there something that's more like 15?

You can use an A6 or V710 as a track day tire. I use V710s on my S2000 and know a lot of other guys that do the same with 370Z's, Mustang Cobra's, Miatas, M3's and STi's. I don't do enough events to chord a set of tires before they heat cycle out. A lot of guys who time trial with buy a fresh set of V710s, time trial on them until they get slow, then get a new set and use the old slow ones for practice.

Two of my favorite track day tires are the V710s and NT01s. Yokohamas are garbage. Bridgestone RE11's are fantastic street/track tires as are the Hankook RS3's. I'd like to try the Hankook with the C91 compound but I'd have to buy a set of 18" wheels.

a6 are great for circuit. for real high track temps and longer races, you might consider the others (r6, etc).

what i do is about 3 track days a year at my current rate.. each track day is 5 20 minute sessions. and then that's it for the track "season" for me. so that equates to 15 heat cycles right? ..sorry, i'm new at this.


what i'd like is a nice r compound that'll last a "season" for me.

A6's for a tracktire??? I've heard of using them for time attack where you need a grippy tire without being able to heat them up, but not as a general track day tire. Heck, in AutoX people are considering spraying them after 1 run on a 70* day. Seems to me they'd get too hot and greasy in just a few laps time.

I have had nothing but great experiences with the NT01's. And you can drive them DD if you have to. I would not recommend any rain use though.

Well now you have. I've won 8 races this year on them. They are good start to finish in a 35-40 minute race. Much faster than R6 (at least a second per lap)

I dont know anyone who isnt running the A6 if they can. One of the C5 Mafia had Hoosier send him R6s instead of A6s by mistake. The result was 1.5 seconds slower at Road Atlanta.

Youre the only person Ive ever heard say they are fast to the cords though. Most everyone else I know says that after 10 HCs or so, they drop about a 1-1.5 seconds, which in some cases is still faster than an R6, but definitely not prime tire type lap times. :shrug:

Those C5 guys win them so often, they don't know what cords are They do slow down some, but still faster than R6 before cords in my experience. And after 10HCs or so, they are close to cords depending on where you are running them, heat, etc.
