For those running Khumo Victoracers what cold and hot tire pressures are you guys running in Spec7, ITA, or ITB. I'm running an FB in ITA. My first (and last) event was run in the fall (85 degrees) with 30 pounds of pressure cold.

Tire rack says this: "Inflation Pressures

The V700 will work well on most cars with inflation pressures between 35 and 40 psi ("cold" inflation pressures for autocross use and "hot" inflation pressures for racing use). Cars that are light, well balanced and relatively easy on tires will find slightly lower pressures may work for them, while heavy, high horsepower cars that are generally harder on tires may find that they need slightly higher inflation pressures.

Generally adding air pressure in small increments (2 psi) to the tires on the end of the car that looses traction first works best. For example, if a car is understeering, add pressure to the front tires. If the car is oversteering, add pressure to the rear tires."

Even if your running Toyo's or other R compound tires your input would be appreciated.

Thanks

At summit point... which consists of mostly right turns (LF is most important)... we ran...

LF - 26
RF - 27
LR - 27
RR - 28

I THINK that was it. We've been on toyos for the last season i cant remember if those are the numbers but that sounds right.

~28-30 and mark'm to start. let pressure out till they stop gainin pressure after a session.
