  What I do is keep reducing psi until the side walls feel mushy in the turns then come up a couple psi. Might not be the fastest but it’s the coolest.

  Pressures are too high if the come in at lap 2 and then drop. You have to be able to get the tires to come in around lap 5 and then keep lap times stable for a few laps before having a slight drop.
  
  The range that u found the tires work best was between 9-11, no matter the track temp, type of track or location(I’ve raced all over the world)
  
  with that in mind find a setup for you kart that likes those pressures and you will find that the kart will be very consistent throughout your session. One magic fast lap is no good.
  
  pm me if you have any more questions I’ll be happy to help.

  Thanks for the help, I will try 9-11 psi. I am curious why EVERYBODY locally runs far higher pressures but I’ll see what happens at the next test day

  It’s possible that everyone locally simultaneously is wrong. ;)
  
  Also possible your lap record holder set his best lap on lap two and then fell off too.
  
  I agree that your pressures are too high. As Rene said, if the kart comes in on lap 2 and then falls off rapidly, your pressures are simply too high. The tire is designed for half the air you’re running. Keep in mind that air affects the way the tire physically works too, and changes the contact patch.

  Ok, here is a follow up tech question for all of you. When I started karting, I wanted my kart to look different than what everybody else was running so I had all my low volume wheels powder coated a different color. Is it possible that the powder coating is insulating the tire and air inside the tire from the cooling air flowing past the wheel?
