1. TireMinder TM-77: Best Overall
The TireMinder TM-77 is a well-rounded trailer TPMS that we found to be the most balanced option after comparing specs and owner feedback. It supports up to 8 tires, making it suitable for larger trailers, and its flow-through sensors let you add air without unscrewing the sensor. The solar-powered display is clear and bright, and the system provides both pressure and temperature alerts. In our evaluation, the TM-77 consistently received high marks for reliability and ease of use.
However, one notable limitation is that the sensor batteries are sealed and cannot be replaced; when the battery dies, you must buy a new sensor. This can be a long-term cost consideration. If you prefer user-replaceable batteries, you may want to look at other options. Also, the display can be a bit large for some dashboards. Skip this if you need a system for a single-axle trailer or prefer a more compact display.
- Monitors up to 8 tires simultaneously (ideal for dual-axle trailers)
- Flow-through sensors allow easy inflation without removal
- Solar-powered display with USB backup; adjustable pressure and temp alerts
Pros: Excellent range and reliable signal; Easy to install and intuitive interface
Cons: Sensor batteries are not user-replaceable (must replace whole sensor)
2. EEZTire T515: Best Value
The EEZTire T515 offers great value for money, especially for those with trailers up to 6 tires. We compared its features against its price point and found it delivers solid performance. The sensors use replaceable batteries, which is a significant advantage over sealed units. The color display is easy to read, and the system allows you to set custom high and low pressure and temperature alarms. Owner feedback highlights its accuracy and quick alerts.
On the downside, some users report occasional signal dropouts on longer trailers, particularly over 30 feet. If you tow a very long fifth-wheel or gooseneck, you might experience intermittent connectivity. Also, the display is not solar-powered, so you need to plug it in. Skip this if you need a solar option or have a trailer longer than 30 feet.
- Supports up to 6 tires with replaceable CR1632 batteries in sensors
- Large color display with backlight and adjustable alert thresholds
- Includes mounting bracket and adhesive for easy installation
Pros: Replaceable sensor batteries save long-term cost; Very responsive and accurate readings
Cons: Signal range can be spotty on very long trailers (over 30 feet)
3. TST 507 Flow Through: Premium Pick
The TST 507 Flow Through is a premium system that we found to be the most durable and expandable option in our research. It can monitor up to 22 tires, making it perfect for large RVs, boat trailers, and heavy equipment trailers. The flow-through sensors allow easy inflation, and the batteries are user-replaceable. The display is robust and the signal range is among the best, maintaining connection even on 40-foot trailers. Owner feedback consistently praises its reliability.
However, this system comes at a higher price point, which may not be justified for smaller trailers. Also, the display is larger and less sleek than some competitors. If you only need to monitor 4 or 6 tires, you might be paying for unused capacity. Skip this if you are on a tight budget or have a small utility trailer.
- Expandable system supports up to 22 tires (ideal for large RVs and multi-axle trailers)
- Flow-through sensors with user-replaceable batteries
- Digital display with strong signal range and customizable alerts
Pros: Exceptional build quality and durability; Excellent range and reliable signal even on long trailers
Cons: Higher initial investment compared to competitors
4. Minder Research TireMinder A1A: Best for Simplicity
The TireMinder A1A is designed for those who want a no-fuss TPMS. In our evaluation, it stands out for its simplicity: the sensors come pre-paired, so you just screw them on and the display auto-detects them. It monitors pressure only, which is sufficient for many users. The display is small and uses simple LED lights to indicate status. Owner feedback highlights how easy it is to install and use.
However, the lack of temperature monitoring is a significant omission for those who tow in hot climates or over long distances. Also, the sealed batteries mean eventual sensor replacement. If you need temperature alerts or prefer user-replaceable batteries, this is not the right choice. Skip this if you tow in extreme heat or want comprehensive data.
- Pre-programmed sensors: no pairing required, just screw on
- Compact display with simple LED indicators
- Monitors up to 6 tires with automatic detection
Pros: Extremely easy to set up and use; Affordable price point
Cons: No temperature monitoring (pressure only); Sensor batteries are sealed and non-replaceable
5. RVGUARD TPMS: Budget Friendly
The RVGUARD TPMS is a budget-friendly option that we researched for cost-conscious buyers. It offers pressure and temperature monitoring for up to 6 tires, with a color display and replaceable sensor batteries. For the price, it provides good value. Owner feedback notes that it works well for small to medium trailers.
However, the build quality is noticeably lower than more expensive systems, and the signal range is shorter, which can cause dropouts on longer trailers. Some users report that the sensors are less accurate at very low pressures. If you have a large RV or tow over 25 feet, look elsewhere. Skip this if durability and range are top priorities.
- Affordable system with color display and replaceable sensor batteries
- Monitors pressure and temperature for up to 6 tires
- Includes multiple alert modes: visual, audible, and flashing
Pros: Very low price for the features offered; Replaceable batteries in sensors
Cons: Build quality feels less premium; Signal range is shorter than average
6. Mopar TPMS (Chrysler/Dodge/Ram OEM): OEM Integration
The Mopar TPMS is an OEM solution for owners of Chrysler, Dodge, or Ram trucks that already have factory TPMS. It allows you to add trailer tire monitoring without a separate display, as the information appears on your truck’s instrument cluster. In our research, this is the best option for those who want a clean, integrated setup. The sensors are built to OEM standards and are very durable.
However, this system is not universal and only works with specific truck models. It also only monitors pressure, not temperature. If you don’t drive a compatible truck, or if you want temperature alerts, this is not for you. Skip this if you have a Ford, Chevy, or other brand, or if you need temperature data.
- Designed specifically for Chrysler/Dodge/Ram trucks with factory TPMS
- No additional display needed; integrates with truck's instrument cluster
- Sensors mount on trailer wheels and communicate with truck's system
Pros: Seamless integration with compatible trucks; High durability and reliability as OEM part
Cons: Only works with specific truck models (Chrysler/Dodge/Ram); Limited to pressure only, no temperature monitoring
7. ATOMI AT102: Compact Design
The ATOMI AT102 is a compact and portable TPMS that we evaluated for those who prioritize a small footprint. The display is about the size of a key fob and can be mounted anywhere with the included adhesive. It runs on a rechargeable battery, so no power cable is needed. Owner feedback appreciates its simplicity and small size.
However, the sensors have a higher failure rate compared to more established brands, and the signal range is limited to about 20 feet, which may not be enough for longer trailers. The build quality is also less durable. If you have a short trailer and want a minimalist system, this could work, but for reliability and range, we recommend other options. Skip this if you tow over 20 feet or need long-term durability.
- Very small and lightweight display that mounts anywhere
- Rechargeable battery with USB charging, no hardwiring needed
- Monitors pressure and temperature up to 6 tires
Pros: Extremely compact and portable; Simple to set up and operate
Cons: Sensors are not as robust; some report early failure; Signal range is limited to about 20 feet
Frequently Asked Questions
What is a trailer TPMS and why do I need one?
A trailer TPMS (Tire Pressure Monitoring System) continuously monitors the air pressure and temperature of your trailer tires while you drive. It alerts you to dangerous drops in pressure or excessive heat buildup, helping you prevent blowouts, improve fuel efficiency, and extend tire life. For safety, especially at highway speeds, a TPMS is highly recommended for any trailer.
How many sensors do I need for my trailer?
The number of sensors depends on how many tires your trailer has. Most systems support 4, 6, or 8 tires. For a single-axle trailer, you need 2 sensors; for a dual-axle, 4 sensors; and for triple-axle, 6 sensors. Some systems are expandable to 10 or more for large RVs. Choose a system that matches your tire count or allows future expansion.
Can I install a trailer TPMS myself?
Yes, most trailer TPMS systems are designed for DIY installation. You simply screw the sensors onto the tire valve stems (or replace the valve core with flow-through sensors) and mount the display in your vehicle. No special tools or wiring are required, though some displays need to be plugged into a power source. Always follow the manufacturer’s instructions.
What is the difference between flow-through and cap sensors?
Flow-through sensors replace the valve core and allow you to add air without removing the sensor. Cap sensors screw onto the existing valve stem and must be removed to inflate the tire. Flow-through sensors are more convenient but are usually more expensive. Cap sensors are simpler and cheaper but require removal for inflation.
How long do sensor batteries last?
Sensor battery life varies by model and usage. Typical battery life is 1 to 3 years. Some sensors have user-replaceable batteries (like CR1632 or CR2450), while others are sealed and require sensor replacement when the battery dies. Check the product specifications for battery type and replaceability before purchasing.
Our Verdict
After researching and comparing the top trailer TPMS systems, our top pick is the TireMinder TM-77 for its excellent balance of features, reliability, and ease of use. It offers flow-through sensors, solar-powered display, and supports up to 8 tires. For a more budget-friendly option with replaceable batteries, the EEZTire T515 is a strong runner-up that provides great value without sacrificing essential features.
