Hoosier air pressure?

ANYONE running AS303's???? what pressure do you like???

For concrete 44 front/ 40 rear.

For asphalt 36 front/ 32 rear.

We found this to be the best and identical times on the skid pad. The lower pressures for the asphalt allow the ties to bite more on the slipperier surface. The tires loke the higher psi on the grippier concrete.

Incidently a psi of 40 front / 36 rear is slower

These are col starting pressures and we keep the tires at those pressures as they heat up. You may have to vary these sliightly concerning tire temps, camber and toe and track conditions along with ambient and track temps. We haveactually sprayed water on them between runs when the asphalt was at 130 degrees.
