stock tire pressure for Track

[LiveWire]

Just wondering what people think would be good PSI. I think the KDW2's max psi is 44. I have mine at 32 and I know the fronts at least heat up to 38 from street driving. Anyone think 35psi cold is a bad idea for the track? I like it that high for the street, been too lazy to pump them up though. I'll be swiping the sidewall with white shoe polish at the track to check for roll-under, so maybe I'll just find out the hard way.

I have run mine at 40 for autoX. That was suggested by more experienced drivers at the track.

Whatever pressure you start at, you should make several marks on the sidewall (white shoe polish works well), to see how far you are rolling the tires over.

Running the Eagle F-1's last year, I was up to 55psi on the last session, to keep the sidewalls from rolling under.

Chalk works good too and comes off much more easily

I have experienced that you need over 40 to keep from rolling the sidewalls..

I had like 35 or so in last year at a road course and totally ruined the front two from not enough pressure.

Last year if I remember correctly, I ran 44 in the front left and 40 in the front right. This was with 225/40/18 tires

The tire pressure has a direct relationship to the design of the tire. Unless you find someone running the same tire/wheel set-up, and running about the same speeds as you are, it's something you will have to work with.

Someone correct me if I'm wrong here, but I would suggest near the maximum pressure listed on the tire as a starting point, and working from there.

I ran 42psi last year at Nationals and that seemed to work really well on the track...cut down on my sidewall rollover a ton.
