Description
Don't risk a blowout or costly damage to your RV – get a TPMS
When you're in the driver's seat, it's nearly impossible to feel low pressure
Unless you continuously monitor the tires, you’ll never know if the pressure is too low – until it results in a flat tire or blowout. At that point, the damage is often costly and extreme.
A Tire Pressure Monitoring System (TPMS) continuously monitors the air pressure and temperature in your tires, while you’re towing. When either one goes out of spec, the system alerts you so you can pull over safely and check things out.
We recommend the TST TPMS because it’s the most reliable on the market
Each TST kit includes all the parts necessary to monitor your tires: A cordless color monitor, tire sensors, repeater/booster (to guarantee a reliable signal at all times), windshield mount, charging cable, and instructions.

Determine the right number of sensors
| Number of axles on your trailer | TST sensors needed |
| Single axle (most Airstreams 16-22 feet) | 2 sensors (NOT AVAILABLE for this monitor, please buy the 507 system instead) |
| Double axle (most Airstream trailers 23-33 feet) | 4 sensors |
| Triple axle (Airstream Classic 34-footers) | 6 sensors |
| Truck and double axle trailer | 8 sensors |
If you need more than 8 sensors you can add them here.
