As a general rule for tire PSI with regaed to track purposes here are the facts. A tire should see an increase of 10-15% in PSI from cold PSI.... After a track session. A session consists of 15-20 minutes. Now if the PSI is 20% or more than cold it means you are overheating the tires. That means you need more PSI cold. Conversly, if PSI increase is less than 10% you should start the session with less PSI. I start most of my tires at 32PSI for the track & adjust acordingly. NJMP Lightning June 12, hope no rain.
