The stock air gauge has to go. I have found one draw back to the carbon fiber wheels they will add air to your tires as the sun warms the dunes and wheels. I have been trying to find the upper limit of my tires. In camp I aired the paddles up to 6 lbs, which is the upper limit. At China Wall at about the half way point the rear would break lose and end the climb It was time to let some air out. My stock air gauge broke. I had to use the SWAG method of counting too 15 as I let air out of the tires. Result made it to the top. When I got back in camp check the air pressure and it was at 6 lbs. I need something small and easy to read I due not want to have bring my reading glasses
