6 Best RV Trailer TPMS in 2026: A Practical RV Guide
Tire pressure monitors for RV trailers only: four-tire and six-tire kits compared by axle count, signal booster, pressure range and charging.
By Hardcastle's RV Editors
10 min read6 products evaluated
A trailer-only TPMS has a simple job: watch two, four or six tires that sit 25 to 40 feet behind the cab. This guide ranks six kits by how well they cover a tandem or triple-axle trailer, and how well their signal reaches the display.
Axle count sets the sensor count, so each entry states how many sensors ship. Pressure range and booster support come next, because a trailer's tires usually run higher pressure than a car's.

How We Built This Shortlist
Each pick was assessed across 5 criteria weighted for real-world use.
- Axle coverage
- We compared sensor counts against two, three and four-tire-per-side trailers.
- Pressure range
- We compared stated psi against typical trailer tire pressures.
- Signal support
- We noted boosters and stated transmission distances.
- Power
- We compared solar, USB and cigarette lighter charging.
- Trailer fit statements
- We noted listings that name trailer length or trailer use.
What Matters Before You Choose an RV Trailer TPM
Key buying criteria so you get the right fit the first time.
Sensor count by axle
A tandem trailer has four tires and a triple-axle has six, and many owners add a spare. Buying a kit with fewer sensors than tires leaves some unmonitored. Count tires and spares before choosing.
Pressure range
Trailer tires often run 65 to 110 psi, and a sensor with an 87 psi limit cannot read the high end. The TireMinder i10 4-Pack reads to 199 psi, while the Masoll M13 stops at 87. Compare the listing's range with your tire sidewall.
Signal to the cab
The display is far from the trailer sensors, so a booster or repeater matters. The Masoll RV Booster Kit lists up to 120 ft, and the TireMinder i10 4-Pack includes a booster. Look for a stated range and booster in the box.
Temperature alerts
A hot tire often means a failing bearing or dragging brake before pressure changes. Check that the listing names a high temperature alarm. The Flydew 6-Wheel and Tymate TM12 6-Set list six alarm modes.
Charging method
Solar panels keep the display charged, while a cigarette lighter plug powers it from the truck. Trailers are separate from the truck, but the display sits in the cab. Pick the power style you prefer.
Sensor type and install
Cap sensors screw on the valve stem and flow-through sensors do not need removal to add air. Most of these listings do not state it, except Tymate TM12 6-Set which says external sensors. Confirm the type before buying.
Match an RV Trailer TPM to Your RV
By Axle Count
| Your situation | Recommended pick | Why |
|---|---|---|
| Tandem axle, high pressure | TireMinder i10 4-Pack | 4 transmitters, 199 psi, booster. |
| Triple axle, mid price | Tymate TM12 6-Set | Six external sensors. |
| Tandem axle, long distance to the cab | Masoll RV Booster Kit | Booster to 120 ft. |
| Triple axle, budget, stated range | Flydew 6-Wheel | 6 sensors, 144 psi. |
| Short tandem trailer, low pressure | Masoll M13 | Four sensors under 38 ft. |
Scroll sideways to see every column.
By Budget
| Budget | Recommended pick |
|---|---|
| $30 to $40 | Masoll M13 or Tymate TM7 |
| $40 to $90 | Flydew 6-Wheel or Tymate TM12 6-Set |
| $100 to $250 | Masoll RV Booster Kit or TireMinder i10 4-Pack |
Booster Included vs Add Later
- Booster included
- Signal support ships in the box. TireMinder i10 4-Pack and Masoll RV Booster Kit fit here.
- No booster listed
- Cheaper, but may drop signal on long trailers. Tymate TM12 6-Set, Flydew 6-Wheel, Masoll M13 and Tymate TM7 fit here, and Tymate offers a separate repeater.
Most trailers over 30 ft should default to a kit with a booster, such as the Masoll RV Booster Kit.
By Pressure Needs
| Tire pressure | Recommended pick |
|---|---|
| Above 144 psi | TireMinder i10 4-Pack |
| Up to 144 psi, six tires | Flydew 6-Wheel |
| Up to 144 psi, four tires | Tymate TM7 |
| Under 87 psi, four tires | Masoll M13 |
For a Triple-Axle Trailer Specifically
- Look for
- Six sensors and a display that handles at least six tires, as the Tymate TM12 6-Set and Flydew 6-Wheel list.
- In this comparison
- The Tymate TM12 6-Set ships six sensors and a 12-tire display, and the Flydew 6-Wheel ships six sensors with a stated 144 psi range.
When to Spend More
- Spend more if
- Spend more on the TireMinder i10 4-Pack for the 199 psi range and booster, or the Masoll RV Booster Kit if distance is the issue.
- Save if
- Save with the Tymate TM7 for four tires, or the Flydew 6-Wheel for six tires at a stated range.
Before You Bring One Home
How many sensors does a trailer need?
One per tire, plus any spare. A tandem has four and a triple has six, so the Tymate TM12 6-Set covers a triple-axle.
What mistake do trailer owners make?
Ignoring range. The Masoll M13 reads to 87 psi, which may be below your trailer tire's pressure.
Is the TireMinder i10 4-Pack worth it over the Tymate TM7?
If your tires run above 144 psi or the trailer is long, yes. Otherwise the Tymate TM7 reads up to 144 psi for far less.
How do I set up a trailer TPMS?
Mount the display in the cab, screw sensors on each valve stem, and confirm the readings against a gauge. Place any booster near the middle of the trailer.
How do I maintain one?
Check batteries when you service the tires, keep the solar panel clean and recheck thresholds when you change tires or loads.
