We normally recommend, for novice and intermediate drivers, overinflating street-use tires for driving school use.

This is because when driving on a track at high speeds through corners with normally-inflated (or, if you haven't checked lately, likely underinflated) tires, the rubber may "roll over" or deflect from the wheel rim to such a degree that it may release from the rim and suddenly deflate. As well, the high loads on the tires will cause them to heat up. If they're underinflated, they will heat to much higher temperatures, possibly leading to a catastrophic blow-out.

Higher pressures can help the tires better protect the rims from damage by decreasing roll-over. Raising the tire pressure can improve feel and response (the tires don't feel squishy). Advanced drivers may seek a crisper turn-in and less body pitch and roll.

In wet or cold conditions, conversely, we usually want more heat in the tires.

In the dry, raise the pressure by +5 psi. In the wet, keep it at the normal level (or lower it by -5 psi if you're an advanced driver).

If using R-compound or racing tires, consult with an instructor or experienced racer.
