If I remember, the lower the tread wear number the less time it lasts right? And most of the time, the lower that tread wear the softer the compund, and thus the stickier the tire. In my experience (not much! ) the higher the harder the compound the less the stickyness. I used those cheaper Fuzion ZRI tires on my alst stang. Nice looking tire, actually very nice tread pattern and can get in big sizes. They did pretty damn well at the track. With 4.10 gears I hooked better than I have on any other street tires I have played with. But then again, I never buy really expensive tires either.
