Fortunately for us, our Montana came with wheels rated 3750lbs load capacity and are rated to handle 110 psi pressure cold. The only thing we had to do was have the valve stems upgraded to all metal stems that would handle the pressure. The rubber stems that came on the wheels were maxed out at 80 psi that the GY Marathons were rated at. On the aluminum wheels, the weight and pressure is usually cast or stamped on the inboard side of the wheel.
