These are dry weather track day tires. With full tread they do ok in rain but quickly wear off the grooves. If kept happy from pressure point of view, and flipped on the rims, they will give good life. Grip really gets better mid life and they heat cycle out slowly. You can usually run these down to the cords.

sitting at 657 whp and once heated. I can consistently run a 3.5 sec 0 to 60 with a manual verified by a vbox.

Great track tire. Gets warm and sticky fast, not bad in the rain as long as you don't drive through standing water. Thread life depends on use, alignment specs. First set lasted 2 years 15 track days 6k street miles.

Great tires, but it appears that Simple Tire is buying old stock. The set I just received has a build code of 2016 which is bit old for a race tire. Warning to stay away from simple tire for competition tires.

While I haven't mounted up the most recent set, the NT01 has been my Go-To track tire for years. It won't quite match Hoosier (when new, at least) performance for lap time, but it is a very consistent, easy to drive tire that handles multiple heat cycles with minimal degradation in performance.

Amazing track day tire for the price. For track use these tires are great. Tire life is great, I got a handful of track days plus about 25 days of autocross on my current set and they still have some life left. They are a very neutral tire and you can tell when they are about to slide or break loose. On the street this tire is loud, rides a bit harsh, doesn't get up to proper temps, and will wear down fast.

Excellent Track Day tire.
