    I am getting comfortable with the notion that the thin to win RA1s weren't actually thin to win, rather that we were just slow.
    The thin to win were great at certain places like Eagles Canyon and Hallett and not real bad at TWS or Houston. They were not very good at Cresson for me.

    I've also had good luck with older tires at Hallett

    Where in Ohio would this guy be moving to? We have a couple of racers in the north east ohio area.
    I'm in the process of moving to the Dover/New Philly area.
    Wife is starting at a new job next week.
    I'm probably 2 months away from actually relocating to Ohio
    as I have a house to sell in Texas. I've been hanging out with
    the Texas AI/CMC guys for several years but I don't drive, just
    help mechanic on 3 of the guys cars, take lots of race photos and
    eat brisket and ribs at Hallett. Once I get moved I'll have to
    look up the race schedule and make an appearance at one of
    the races up in the Ohio area.

    PS Sorry about hijacking the tire thread. My bad.

    For my car - aero, slip angle, ambient temp/surface temp, tire temp, load etc. contributes to degradation. I consider them "not competitive" when I've lost a second over the prime. Also, 250* will kill these tires. I cooked a set at TWS testing one year and they were complete junk the next day. I try to keep them below 225*. 200* is better.

    So "not competitive" is when you are only a second faster than the rest of us?

    Have you not realized that Mike started his own "AI-TT" group a few years back. He's in a class of one.
