Track Day Tire Pressure

…then monitored the ambient temperatures, tire temperatures and tire pressures through the day. As the day's temperatures went from 67 to 85 Fahrenheit, the tire that was kept in the shade went from our starting pressure of 35 psi to a high of 36.5 psi. The tire that was placed in the sun and subject…

…"I've used these on my Porsche 968 race car in PRC racing and open track days for years, and have always loved them. They hook-up very well, the steering response is nice, and the tire is very predictable. The optimum tire pressures are easy to figure out, and I've found they work well after a…

…matter, it is not unusual to have more track time (enough to drive several hundred track miles per day) at a typical club event or driver's school than most actual race weekends. And while it's common sense that track use will increase the wear on a car's tires, brakes and shocks, there are less…

…the tire. If your tires are rolling over past the tread pattern, increase negative camber, increase inflation pressure and reduce slip angle while driving to keep the work concentrated in the tread area. Check Your Hot Tire Pressures As soon as you come off the track check your hot tire pressures…

…tires out of direct sunlight between sessions. Heat from the sun can raise tire pressure. • For autocross competition tires, adjust inflation pressure when warm. For road racing competition tires, adjust inflation pressure when hot. Read more, then take a look at Tire Rack's selection of Track…

…track events, lapping days or wheel-to-wheel competition, these pads may cool off too much between stops on the street and possibly provide less initial stopping power than O.E. brake pads. With the increase in ultimate stopping power can also come a significant increase in required pedal pressure,…

…the Pilot Super Sports installed. We have the students drive on our test track around several obstacles and on the skid pad to get a feel for the limits of the car and their tires. One of the techniques we employ late in the day, when confidence has been building, is to induce a little oversteer on…

…"hot" tire pressures that are up to 5 to 6 psi above the tire's recommended "cold" pressure during the day if the vehicle is parked in the sun or has been extensively driven. Therefore, if the vehicle's recommended "cold" inflation pressures correspond with the tire's maximum inflation pressure, it…

In this case the 3-5 psi higher recommended inflation pressure increase helps offset the reduced tire pressures associated with the conditions in which the tire pressures are typically…
