Do I need to upgrade to metal valve stems to use TST?Updated 7 months ago

The cap sensor system that we include with TST tire pressure monitors does not require upgrading your valve stems. You can install cap sensors on the rubber valve stems that came with your Airstream. 

However, if you wish to upgrade to metal 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.
