No prep, new uncut Burris.
Thats your problem, too much shoulder by being uncut.
Where did you race at ?
GSR in Clintonville WI. We were at -3.25 I went down to -2.75, that is were it pushed, I came back to -3.
Did you reset cross after changing camber a half degree?
I have not scaled it with the camber change, the couple weeks before I have been adding cross and it has just gotten faster. Last race on the ride home she told me this was the first time she's felt comfortable with the kart.
Which chassis ? What were all your set numbers going in ? Including cambers and caster.
Millennium Impulse, she runs in Lo206 sportsman 350lb. I haven't scaled it in a couple weeks and have added cross since then. At -3 it has the fastest lap times she's ever had. I'll see about a set of semi rounds and see how it works. Might try less camber, more caster tonight in practice and see what it does.
Unless tried and true proven don't know that you want semi round cut, most likely round cuts.
I don't know another way to prove it.
You can look around the pits and on the grid and see what mosr everyone else that's fast is using, if you don't have any local tire guy's that know
Most of the karts had a pretty flat profile on them, a couple had rounder cuts, and a couple had fresh scuffs with the lines still on them.
Did it fix the feathering problem OR did the track just not have as much grip not over working the tire as much, not being up on the inside shoulder should have helped though, Out of hundred plus races a year I could count on one hand the amount of times we've rerun the same tires for heats and feature, and if we did they would get resurfaced between runs, good chance the graining your seeing now is from sliding.
I have done many sets of tires for guys that run at GSR. Good folks that are winning as well. We use our Intermediate profile that keeps some shoulder on the tire to the first mold line, rounds to the wear dots, then is flatter between the wear dots with very slight crown.
Thanks and God bless,
It wore a lot more even this week than it had been. She did mention a slight push in the later half of the feature. We were going to work with some more rear stagger this week. She could run a lower line coming off the corner than most of the others though.I have done many sets of tires for guys that run at GSR. Good folks that are winning as well.

If you're just wearing the inside of the RF, that tells me the kart is too tight and your driver has too much wheel input (turned left) to keep it on the inside shoulder too long which builds localized heat and wear.
Get the kart loosened up (either more rear stagger, more nose, more anything that helps get the car off that RF.)
Feel free to give us a call at the shop during business hours and I'd be glad to talk with you in more detail about our tire program for GSR.
