6 Best TPMS For Dual Axle Trailer in 2026: A Practical RV Guide
TPMS options for a dual-axle trailer, led by kits that set alarm values per axle (Taimster, B-Qtech), plus GUTA, TireMinder and Liwogi kits.
By Hardcastle's RV Editors
10 min read6 products evaluated
A dual-axle (tandem) trailer has four tires, and the front and rear axle can carry different loads, so per-axle alarm values are a useful feature. This shortlist leads with kits that state separate alarm values or independent alarms for dual axles.
Two of the picks are large kits with ten sensors, and one TireMinder kit includes only two transmitters, which is noted. Pressure ranges are quoted only where the listing gives them.

What Matters Before You Choose a TPM For Dual Axle Trailer
Key buying criteria so you get the right fit the first time.
Per-axle alarm values
Front and rear axles on a tandem can carry different loads and run different pressures. Taimster Ta6 and B-Qtech 6-Sensor Solar let you set alarm values per axle. Check the listing for this feature.
Four tires on a tandem
A tandem has four tires, so a four-sensor kit covers it. Larger kits cover a tow vehicle too. Count the tires you want on screen.
Transmitters included
TireMinder Solar includes two transmitters, so a four-tire tandem needs two more. A kit that covers fewer tires than listed adds cost. Count included sensors.
Pressure ceiling (dual-axle)
TireMinder Solar tops out at 70 psi, while Taimster and GUTA state 188 psi. Many tandem tires run 65 to 80 psi, so check the sidewall. A low ceiling can rule out a model.
Theft protection
Taimster 10-Sensor includes anti-theft locking nuts. A tandem parked at a campground is a target. Look for locking nuts.
