If your running the Skats, the normal PSI to run those at will be 8 psi. They will climb better at the lower pressures, but dune better at 8 psi. Dont run lower than 6 psi you will tear the tire apart from the inside out. The paddle is stronger than the casing.
We can tell when the tires have been run too low!!!!!!!!!
What eventually happens you will start seeing bubbles in the casing and also it will look like the paddles are pulling off the casing but its actually the plys of the casing being pulled apart by the paddles.
