Choosing the best trailer tire pressure monitoring system can give you early warning when a trailer tire begins losing pressure, long before you feel anything unusual from the driver’s seat. By the time a low tire starts affecting how the trailer pulls, the tire may already be overheating or suffering internal damage.
A trailer tire pressure monitoring system (TPMS) gives you another line of defense by monitoring tire pressure and temperature while you’re towing.
That’s especially useful with travel trailers, horse trailers, equipment trailers, and utility trailers, where a tire problem can quickly turn into damaged fenders, wiring, flooring, or cargo.
After comparing pressure range, monitoring capability, signal reliability, expandability, ease of use, and price, these are our three choices for the best trailer tire pressure monitoring systems for towing.

Best Trailer Tire Pressure Monitoring System Choices
| Recommendation | Trailer TPMS | Best For |
|---|---|---|
| Best Overall | TST 507 | Frequent towing and longer or heavier trailers |
| Premium / Multiple-Trailer Choice | TireMinder i10 | Multiple trailers and expandable setups |
| Best Budget Choice | Tymate TM2 | Affordable monitoring and occasional towing |
TST 507 — Best Overall
The TST 507 Series with four cap sensors is our best overall choice for someone who tows regularly and wants a dedicated trailer TPMS rather than relying on a smartphone.
The four-sensor system uses a color display and monitors both tire pressure and temperature. It provides audible and visual warnings for potentially dangerous conditions such as high or low pressure, high temperature, and rapid pressure loss.
One of the most important features for trailer use is the included signal repeater. The farther the trailer tires are from the receiver in the truck, the more important reliable communication becomes.
The TST 507 also has plenty of pressure capability for demanding trailer applications, and additional sensors can be added if your setup grows later. Its external cap sensors use replaceable batteries rather than requiring the entire sensor to be discarded when the battery dies.
Why We Chose the TST 507
The biggest advantage is that this is a serious towing-oriented system rather than simply an inexpensive tire monitor.
You get a dedicated display, pressure and temperature monitoring, a signal repeater, high-pressure capability, replaceable sensor batteries, and the ability to expand the system.
For somebody pulling a horse trailer, equipment trailer, travel trailer, or other valuable trailer regularly, that combination makes the TST 507 our Best Overall choice.
Best for: Frequent towing, horse trailers, equipment trailers, travel trailers, and longer or heavier trailer combinations.
TireMinder i10 — Best Premium / Multiple-Trailer Choice
The TireMinder i10 makes the most sense for someone who owns multiple trailers or expects their TPMS setup to grow.
The i10 uses its own color display rather than requiring you to keep a smartphone app open while driving. It can monitor a large number of tires simultaneously and can store multiple vehicle configurations.
That makes it particularly useful if you tow more than one trailer or want to expand the system later.
The four-transmitter version we selected includes four external tire sensors along with a signal booster to help maintain communication between the trailer sensors and the monitor in the tow vehicle.
It also provides pressure and temperature monitoring, giving you warning of developing tire problems while you’re still behind the wheel.
Why We Chose the TireMinder i10
Its biggest strength is flexibility.
If you have a horse trailer today but also pull a camper, equipment trailer, or another trailer, being able to manage multiple configurations can be genuinely useful.
The dedicated display is another advantage because your trailer-tire information stays visible without occupying your phone.
For someone building a more advanced monitoring setup or regularly switching between trailers, the TireMinder i10 earns our Premium / Multiple-Trailer Choice.
Best for: Multiple trailers, larger towing setups, and owners who want an expandable TPMS.

Tymate TM2 — Best Budget Choice
You don’t necessarily have to spend several hundred dollars to add tire-pressure monitoring to a trailer.
The Tymate TM2 gives budget-conscious trailer owners a four-sensor system with its own display rather than requiring a smartphone.
The version we selected monitors tire pressure and temperature and provides warnings for conditions such as high or low pressure, high temperature, and rapid leakage.
The display can use solar power with USB charging available as a backup, which helps reduce the amount of wiring and charging equipment needed inside the tow vehicle.
Why We Chose the Tymate TM2
The biggest attraction is value.
It provides the core functions most trailer owners want—individual tire-pressure monitoring, temperature monitoring, warning alarms, and four external sensors—at a fraction of the cost of the premium systems.
There is a tradeoff.
For frequent towing, longer trailers, or more demanding setups, we prefer the towing-oriented features and signal-boosting hardware included with the TST 507 and TireMinder i10.
But for a utility trailer, smaller camper, or occasionally used trailer, the Tymate TM2 offers an affordable way to start monitoring trailer tires from the cab.
That makes it our Best Budget Choice.
Best for: Budget-conscious owners, smaller trailers, utility trailers, and occasional towing.
TST 507 vs. TireMinder i10 vs. Tymate TM2

Why a Trailer TPMS Is Worth Having
Your truck’s factory tire pressure monitoring system normally monitors the truck’s tires—not the tires on a conventional trailer behind it.
That leaves the trailer tires largely invisible from the driver’s seat.
A trailer TPMS can alert you to pressure loss while you’re moving instead of leaving you to discover the problem when the tire is already badly damaged or completely flat.
Temperature monitoring adds another useful piece of information. An abnormal increase in tire temperature can provide another warning that something isn’t right.
A TPMS does not replace regular tire maintenance.
You should still inspect your trailer tires before towing, check cold inflation pressure, examine tread and sidewalls, inspect valve stems, watch tire age, and make sure each tire has sufficient load capacity.
Think of TPMS as another layer of protection—not permission to ignore the tires.
Trailer TPMS for Horse Trailers
Horse trailers are one application where a good TPMS makes particularly good sense.
A trailer-tire failure isn’t just inconvenient when you have horses aboard. A shredded tire can damage the trailer, and being forced onto the shoulder of a busy highway creates an entirely different problem when you’re hauling live animals.
Many bumper-pull and gooseneck horse trailers use tandem axles, which means a four-sensor TPMS conveniently covers all four trailer tires.
For regular horse hauling, we favor the TST 507 or TireMinder i10 because the selected versions include signal-boosting hardware and are better suited to demanding towing applications.
If the trailer is used only occasionally and the towing distance is relatively short, the Tymate TM2 provides a considerably less expensive entry point.
What to Look for in a Trailer Tire Pressure Monitoring System
Pressure Range
Make sure the TPMS can handle the pressure required by your trailer tires.
This becomes especially important with higher-load-range tires on horse trailers, equipment trailers, fifth wheels, and heavier travel trailers.
Don’t buy a monitor first and discover afterward that its pressure range isn’t appropriate for your tires.
Signal Range
Trailer TPMS sensors have to transmit information from the trailer wheels to a receiver inside the tow vehicle.
The longer the trailer, the more challenging that can become.
For longer trailers or frequent highway towing, a system that includes a repeater or signal booster can be worth the additional cost.
Pressure and Temperature Monitoring
Pressure is the obvious measurement, but temperature information is valuable too.
A tire that is building abnormal heat may be developing a problem even before pressure falls dramatically.
Neither measurement replaces physical inspection, but together they give the driver a much better picture of what is happening behind the truck.
Replaceable Sensor Batteries
External valve-stem sensors require power.
Sensors with replaceable batteries can reduce long-term ownership costs because you don’t have to replace the entire sensor simply because its battery has reached the end of its life.
Dedicated Display vs. Smartphone
A dedicated display adds another device to the cab, but there’s a major advantage: your tire information remains visible without tying up your phone.
App-based systems can reduce dashboard clutter, but some drivers would rather have trailer-tire information permanently displayed while towing.
All three systems we selected use dedicated displays.
Number of Sensors
A tandem-axle trailer normally needs four sensors—one for each tire.
But think beyond what you need today.
If you may eventually want to monitor additional trailer tires, another trailer, or other tires in your towing setup, buying an expandable system now can prevent you from replacing the entire system later.
TPMS Doesn’t Replace Correct Trailer Tire Pressure
A TPMS warns you when tire pressure moves outside the limits you establish. It does not determine what pressure your trailer tires should be running.
Correct inflation still depends on the tire, load, trailer specifications, and manufacturer requirements.
If you’re unsure whether your trailer tires should always be inflated to the maximum pressure printed on the sidewall, read our Trailer Tire Pressure: Should You Always Run Maximum PSI? guide.
Tire capacity is also only one piece of the towing equation. Your trailer’s GVWR and GAWR establish important weight and axle limits regardless of what the TPMS monitor says.
Trailer TPMS Installation Tips
Most external trailer TPMS systems are fairly straightforward to install, but a few details matter.
Install the sensors according to the manufacturer’s instructions and confirm that your valve stems are suitable for the sensors being used.
Program the correct pressure and temperature warning thresholds rather than simply accepting settings you don’t understand.
After installation, verify that every sensor is communicating with the monitor before heading onto the highway.
If the kit includes a repeater or signal booster, install it where the manufacturer recommends instead of assuming the system will work just as well without it.
Finally, keep a manual tire-pressure gauge in the truck. If the TPMS reports something unusual, a handheld gauge gives you a quick way to verify the reading when you stop.
Frequently Asked Questions
Do I Need TPMS on My Trailer?
Not every trailer requires an aftermarket TPMS, but it can provide early warning of tire-pressure loss or abnormal temperature while towing.
Its value increases with highway use, longer trips, expensive trailers, heavier loads, or valuable cargo.
Can I Put TPMS Sensors on Trailer Tires?
Yes. External trailer TPMS sensors typically attach to the tire valve stems.
Always follow the TPMS manufacturer’s installation instructions and valve-stem requirements.
How Many TPMS Sensors Do I Need for a Tandem-Axle Trailer?
Normally four—one for each tire.
Additional sensors may be useful if you want to monitor other tires and the TPMS supports expansion.
Does Trailer TPMS Show Tire Temperature?
Many trailer TPMS systems monitor both pressure and temperature, including the three systems selected in this guide.
Temperature should be treated as another warning tool rather than a substitute for regular tire inspection.
Do Trailer TPMS Sensors Need a Repeater?
Not always.
Trailer length, receiver location, interference, and the TPMS design can all affect wireless communication.
For longer trailers, a repeater or signal booster can improve reliability. The TST 507 and TireMinder i10 versions selected for this guide include signal-boosting hardware.
Can I Use TPMS on a Horse Trailer?
Yes.
A four-sensor system works particularly well with many tandem-axle horse trailers because each trailer tire can be monitored individually.
For regular horse hauling, we prefer a system designed for reliable communication over longer towing distances.
Can Trailer TPMS Prevent a Blowout?
No TPMS can prevent every tire failure.
What it can do is warn you about certain developing problems—particularly pressure loss or abnormal temperature—early enough that you may have an opportunity to stop before the situation becomes more serious.
A tire can still fail from road damage, structural failure, age, overloading, or other causes without giving much advance warning.
The Bottom Line
For someone who tows regularly, the TST 507 is our best overall trailer TPMS choice because it combines a dedicated display, pressure and temperature monitoring, a signal repeater, strong pressure capability, and expandability.
The TireMinder i10 is especially attractive if you own multiple trailers or want a monitoring system that can grow with a larger towing setup.
And if your priority is simply adding affordable pressure and temperature monitoring to a smaller or occasionally used trailer, the Tymate TM2 delivers the core functionality for considerably less money.
Whichever system you choose, TPMS works best as part of a complete trailer-tire routine: correct inflation pressure, adequate load capacity, regular inspection, and replacement before age or damage catches up with you.
