I ran these tires on my 2015 Honda civic si at a couple of road course events. Extremely awesome tires for the track as they heated up well and have amazing cornering performance. I was not able to try them in wet conditions but was very impressed with them. The treadwear is also very good as you can run these tires until they show cord. You truly get every dollar out of these tires and I highly recommend these for anyone looking for a semi slick tire that will last as long as possible for the low treadwear. Will be buying these tires again!

I love these tires!

I've been using NT01's on both my track cars (Cobra and Mustang) for over 10yrs. I can't say anything bad about them. They grip and when hot, grip more. I can easily get four weekend sessions or more out of a set on either car. Very good dry tire and not made for wet conditions, although a light mist isn't bad.

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.
