And you my friend are not driving aggressive enough to come close to rolling a tire off of a rim.....if you are running pressure that low ....it would take at least 2 laps to get enough pressure to help the tire from rolling over on it's side wall... then maybe the tire will come up to running pressure of 30#lbs....

And using a Infrared temp gauge is the worst tool you can use to measure tire Temps with .... you have to get down into the rubber to know what is going on in the tire.... Our Tire Temps are 200*degrees to 215*degrees across the tire. and thats with a pressure of 30#lbs Hot inflation.
