TST 507 TPMS Cap 10 Sensor - Full Color Touchscreen Monitor

In this review the TST 507 TPMS Cap 10 Sensor is evaluated for owners who tow campers, trailers, or run multiple-axle rigs and want continuous, readable tire data in a single, portable display. The bottom line: this system is for drivers who prioritize real-time safety and clear visibility, since the larger full color touch screen and strong warnings make it easy to spot heat and pressure problems before they become emergencies. Setup and daily use focus on practical monitoring rather than gimmicks, and the rechargeable USB-C monitor is designed for life on the road.

Key Features

• Full color touch screen: The large, easy-to-read display shows pressure and temperature at a glance so drivers can react quickly in daylight or direct sun.
• Multi-trailer monitoring: The monitor tracks one tow vehicle and up to five trailers, letting owners manage multiple tire banks from a single device.
• Automatic parameter setup: The system sets high and low pressure alerts based on your baseline cold tire pressure, reducing manual calibration work.
• Comprehensive sensor support: With support for up to 46 tires and a 10-sensor kit option, it covers multi-axle trailers, RVs and tandem setups without add-on modules.
• Trip and motion readouts: Resettable trip odometer plus real-time direction, altitude and speed readings help combine tire data with vehicle movement information for better diagnostics.
• Rechargeable USB-C monitor: The internal battery and common USB-C power connection make charging straightforward between trips.

Who It's For

The TST 507 is aimed at RV owners, campers, and towing professionals who need continuous, accurate tire monitoring for multiple trailers or heavy rigs. Its touch screen and clear alarms are especially useful when quick decisions matter on long highway hauls.

Those who haul single-axle trailers occasionally or who prefer cheap single-sensor kits may find the 10-sensor package more capability than necessary; similarly, anyone requiring OEM integrated TPMS that works through a vehicle instrument cluster should consider factory options instead.
