Do I need to upgrade to metal valve stems to use TST?Updated 19 days ago
The cap sensor system that AIR GEAR includes with TST tire pressure monitors does not require upgrading your valve stems. You can install cap sensors on the metal/rubber valve stems that came with your RV.
However, if you wish to upgrade to all-metal (steel) stems at your next regular tire change, there's no problem with that.
Cap Sensors vs. Flow-Through Sensors
If you have a motorhome with metal valve stems, cap sensors are an appropriate solution, but for ease of adding air to the tires, you may choose to purchase flow-through sensors instead. You can purchase these directly from TST.
NOTE: We only recommend "flow-through" sensors for motorhomes that have metal valve stems. Metal stems are required for flow-through sensors.
