i run the same tire.
Generally let it see more smoke with very first pass on them, then normal..” just see smoke and get out” routine.
My guess is( despite what others had happen) is the track was probably not great. It was 90 degrees + up here last weekend. 131 is usually very good. Guy i race with( Duster with R5P7 deal) had consistency issues past weekend at the hit, and he normally doesn't.
Once a radial spins, you are done, it wont recover.
All you can do is dial it for what you have, and tighten it up at the big end, if it seems to stick.... easier said than done.
You racing in Terre Haute this weekend?
