240Z - tire pressures?

Guys,

Any guidance on what hot tire pressures to target on an ITS 240Z (225x50x14 on a 14x7 rim) for both;
-Hoosier R30S03's
-Kumho Ecsta

Thanks!
Jeff

For the Hoosiers try 29 all around cold to start. I always measure temps, not pressures when they're hot so I couldn't say for sure, but I think around 36 hot.

Re; Hoosier pressures. You can run as high as 40psi hot w/ these tires. In fact low pressures cause 'rubber nugget' buildup.
Don't know anything about Kumho's
Bill Miskoe

In fact 29 psi cold causes ARRC victories, in 240Z's.

Thanks for the tips all. I would normally like to use temp profiles as well however rigth now my only pit crew (wife) spends most of the event taking care of our 6 month baby. I'm just happy I still get to go to the track http://Forums.ImprovedTouring.com/it/smile.gif 6 month old and she has been to 3 races already!
