4th weekend and they were junk.
I could run them at 3 weekends, but it wasn't fun. This also is very track dependent. MSR-C is a slick track, but it seems to like tires w/ a weekend already on them. Hallett, as I recall (been a while) likes new rubber w/ no heat cycles.

My best recollection is new tires during weekend 3.
