High Pressure Valve Stem Replacements For Class C RV Tires


Hello, I have a 2020 Dynamax Isata 3, which is a Class C RV that was built from the factory, which utilized a 2018 Mercedes-Benz Sprinter 3500 chassis. It is a DRW dually with 6-lug steel wheels. The tire itself shows a max inflation of 80 psi, however, the sticker inside the door of the chassis states to run at a maximum of 60 psi. I recently had a flat tire wherein the bead blew out one of the outside wheels. The tire shop informed me that the tire appealed to fail from being under-inflated all tires were inflated to 57 psi at the time and noted that the rig did not have high pressure valve stems installed on any of the Vanco LT215/85 R16 E1 All-season tires installed on the RV. They also noted that they did not sell replacement high pressure stems, but if I bought my own they would install them on my rig to prevent potential future issues. So my question: is the Americana High Pressure Rubber Snap-In Valve Stem - 1-1/2inch Long - Up to 80 psi the correct replacement valve stem to purchase from you? Thank you in advance.


Helpful Expert Reply:

Yes, The Americana High Pressure Rubber Snap-In Valve Stem # AM20904 would be the correct replacement valve stem for you.

This stem is a high pressure rubber valve stem and is 1-1/2 inches long. It will fit wheels with PSI ratings in excess of 65 psi. The maximum tire pressure is 80 psi.

I attached a review video link below.
