A new tire on the horizon being adopted by NT-01 users is the Maxxis RC1. They're supposed to be grippier but have the same wear characteristics as the NT01's. They're basically a DOT slick tire, with only minimal tread, so they'll suck in the wet but excel in the dry.

It appears that they lack proper sizes for the fronts. NT01s are great but they wear so fast ... I just got a set of cheap R11s and put them on my street rims. It is a good option for the rain too as the NT01 s&^%k in Texas rain.

"NT01s are great but they wear so fast." This has not been my experience. I get 18+ heat cycles from the 18" NT-01 on a 3200 Lb. 993, 245 in front, 275 in the rear. Rapid wear may be an alignment problem? I run about 3 Degrees front and rear. I say "about"...can't give all my secrets away.

Fast is all relative. Thanks for putting out some numbers. I just had a 2-day DE that offered 4 double sessions each day (~20 mins each). I may have skipped one session that I had 15. I will make another WE like this with this set. Compared to your numbers, that does not sound too bad. I just need to drive less ... I will use up my set a 8 year old street tires over the next weekend (should be fun!) and will go with a set of RE-11 that I got relatively cheap from tirerack. This will be my new set for track / rain tires.

Kinf of late to the party here, but interested in the kind of wear I can expect out of these. My aligment and suspension are suboptimal, and wear will require a tire flip shortly.

Lots of mentions of heat cycles in this thread, but that's not really helpful if in fact the NT-01 will still grip until physically worn out. Is a heat cycle a "45 minute enduro race" or a "20 minute DE session including warmup and cool down"? I don't think heat cycles are the right measure here for a DOT entry R comp tire.

My usage is generally 20 minutes sessions, so figure 17 minutes of driving at (my) limit on a street suspension.

On this basis how much wear is typical? I am at ~ 16 sessions, tires are worn on the outisides and ready to flip.

Would love to get 35- 40 sessions out of the rears. The fronts are less worn. Thoughts?

Cheers

I've got 16 days( ~4sessions/day 20-90min ea) ~2700mi and mine still have a lot of life I should get through the rest of the season w/ them

You need more camber

Matt Lane

Thanks Bill - that is excellent wear indeed!

The need for more camber is a given. What are you now running?

The question I am now asking myself is: is it even worth it on a dual purpose car? If my suspension is currently maxed out (or close) - what's the point of driving fast tires on their outside edges, losing performance and causing premature wear. I'd probably be better with sticky street tires that will at least lay flat in a corner. Slower compound, maybe, but better optimized for sure.

This is my first experiment with R-tires. Next step is either a suspension upgrade and more aggressive alignment - or back to street tires and just get my left hand ready for more passing signals!

Not looking to be a hero - just like the stick of these new tires and trying to make it work,

Cheers

Matt,
The nittos have the little wear triangles around the edges to gauge your wear. I am also maxed on negative camber with stock suspension mounting points. I find that about 37 psi hot puts the tire right at the wear triangle. I've got 5 track days (4-5, 30-45min sessions each) on my NT-01s and they still look pretty new. The biggest advantage for me is the predictability. They feel the same for the whole session. It gives me more confidence at the limit.

I never heat-cycled a set out with 20 - 30 mins sessions and I never had a track buddy complaining about it. I run them to the cords. To optimize wear, I run them at higher pressures. 39 PSI vs 37 made a noticeable difference. For a sticky tire, they can last long if you watch wear pattern and maybe flip on the rim in the middle of their live. Same would apply to changing the wheel if your track has more war on one side. TWS does and depending on the direction we go, I change them regularly.
