The TST 507 Series TPMS is one of the most reliable and widely used tire pressure monitoring systems among RV owners. Designed specifically for large motorhomes, fifth wheels, and towable rigs, it provides continuous real-time monitoring of tire pressure and temperature, helping help identify pressure or temperature changes before they become more serious, tread separations, and costly roadside damage.
This system features a full-color display and high-quality cap-style or flow-through sensors that transmit live readings every few seconds. Its long-range signal repeater ensures reliable communication even on longer rigs or when towing. Built for durability and accuracy, the 507 Series is a top-tier choice for serious RVers focused on safety and tire longevity.
Key Features
- Monitors up to 22 tires with a 0–218 PSI range
- Full-color LCD display with customizable alerts
- Available with cap sensors or flow-through sensors (no need to remove for airing up)
- Wireless repeater included for extended range and reliability
- User-programmable alerts for high/low pressure and temperature thresholds
- Replaceable batteries in each sensor (CR1632 type)
RV Use Cases
- Monitors all tires on Class A/B/C motorhomes, fifth wheels, or tow vehicles
- Ideal for full-time RVers or those towing long distances
- Early detection of leaks or overheating can provide early warning of conditions associated with tire failure and tread failure
- Useful during pre-trip inspections to confirm proper inflation
Common User Feedback
Pros:
- Highly accurate readings and dependable wireless signal
- Easy-to-read color display with intuitive controls
- Long-lasting, replaceable batteries in each sensor
Cons:
- Higher initial cost compared to basic TPMS units
- Requires manual pairing for initial setup
- Sensors may require occasional resealing to prevent slow leaks
Best Practices
- Mount the repeater: Install the signal booster midway on the RV frame for full connectivity.
- Program each tire position: Label sensors before installation to simplify setup.
- Test weekly: Verify all sensors are transmitting before each trip.
- Replace batteries annually: Keep spare CR1632 batteries on hand for long-term reliability.
Inspector's Note (RV Pro Solutions Insight)
Tire training and RV inspection work both reinforce the same point: a TPMS is an early-warning tool, not a substitute for pre-trip tire inspection. The TST 507 can help an owner notice pressure loss or rising temperature while traveling, but alert settings should be based on the tire and vehicle requirements—not a generic number copied from another rig. I would verify cold inflation, tire age, condition, load capacity, sensor operation, and repeater communication before depending on the display underway.
