I'm running a set of AR-1's for the first time. So far I'm liking them pretty well as a drive-to-the track tire compared to the alternatives that I've tried before. They seem similar to NT01's. After about 25 heat cycles there is still pretty good grip although they're not quite as grippy as when new. However, the tires are also worn down now below the wear bars. I wouldn't run them in the rain like this, but how much tire life is left before they cord? Can I run them down to the cords like NT01's?

6 track days, ~3,000 street + track miles on my set, no cords. Predictable and steady performance drop off, but no cords in my experience.

Believe it was back on day 2 had full wet morning sessions, no grip then with close to "full" tread, and no wet grip now. NT01 is like a Michelin wet race tire in comparison. (Joking, both are terrible wet weather tires .)
