I run at Providence and the way they keep the track, you don't get a lot of tire wear. I've only used two different sets of HT3s this year and have been competing for a top 5 in Stock Heavy (which averages about 20 entries) in more races than not. It doesn't really ever get fast enough to chew on the tires badly. If you're talking about ELs, I know a few of the guys there have been running the same set the entire year.
Come stop by and hang out there one race night and see what you think. Take care,
