I have a 2k duratech atx... After 25k miles on the firehawk tires the rubber no longer grips in the rain from a stop. It had PLENTY of TREADLIFE LEFT though. Guess the rubber hardenend or something. It was okay when I was up to cruising speed. But as soon as I hit a stop sign, it would just slip and it sounded horrible. It bang, rumbled, and screeched. Barely any gas was applied. Solved the problem with a new set of tires.
