240Z - tire pressures?

[powerslide91]

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!

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

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 6 month old and she has been to 3 races already!
