Hey Guys, I have a bit of an annoying problem with the front passenger side wheel, it always goes flat when its on the car, so i checked the valve and thats ok so i decided to inflate it to the recomended 31 psi and left it off the car for a week, it stayed inflated at 31 psi, so decided to put it back on the car, so i took the spare wheel off and put the original wheel back on, left it a few days and it started losing pressure again went to 20 psi . It is a new tubeless tire on the wheel, any idea's ? or suggestions ?

guys
