Running slicks or semi slicks (Toyo R888) I aim for 30psi hot. So on a cool day I start around 26psi, on a hot day start around 24psi. Normally run about 8 laps or 10 minutes. When I come into the pits, I straight away drop any tyre over 30psi down to 30psi and that seems to work well for me. I find the inside front usually runs around 1 or 2 psi when hot depending on which way the track runs. So have to change that around when going to different tracks.
