About
TST RV TPMS (Truck System Technologies) offers a comprehensive lineup of Tire Pressure Monitoring Systems (TPMS) engineered for RV owners, trailer operators, and towing vehicle drivers. Their flagship products — the TST 770 and TST 507 series — provide real-time monitoring of tire pressure and temperature across multiple vehicles and trailers simultaneously. The TST 770 features a large 5-inch color touchscreen with USB-C charging, magnetic mount, and support for both cap and flow-through sensors. It can monitor up to 4 different trailers and up to 110 wheels by adding additional sensors, making it ideal for complex multi-vehicle setups. The system automatically syncs with trailers when in range and drops them when out of range. The TST 507 series offers similar multi-vehicle expandability with color display alerts shown in plain English (Lo Pressure, Hi Pressure, Hi Temp, Fast Leak), supports up to 218 PSI, and includes a repeater for extended wireless range. It is also compatible with all existing 507 wheel sensors. Both systems use durable, waterproof sensors with user-replaceable CR2032 batteries and low battery indicators. TST backs their products with a three-year warranty and USA-based live customer support, making them a trusted choice among thousands of RV enthusiasts seeking dependable tire safety on the road.
