For riders using a performance/sport/track day tire, we suggest around 31-33psi in the front, and roughly 30-32psi in the rear. We would suggest a pound or two more in the front tire. HOWEVER, each tire manufacturer has different pressure requirements and recommendations in order to make a particular tire perform at its best. Now add weather/temperature variances: hot days vs. cold. Thus, our best suggestion is to talk to your local bike shop (where you got your tires) before your track day and get their thoughts on tire pressures for your tire brand and model.
