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 Bowen HigginsRV Editor at RV Gear Lab6 products comparedSpec-sheet researched

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.

RV Gear Lab field notes

The Rig Fit Check

Start with the job: Taimster Ta6 Wireless Solar TPMS leads this shortlist for Per-axle alarms. Use that fit as a reference point, then compare the alternatives against your own space and workload.
Specs that separate the picks: The first details to compare are 6 sensors, solar, booster, 6 external sensors, 4 sensors, 0 to 188 psi. Confirm the exact model and included components before ordering.
Trade-off to plan for: Brand history is limited

Before you buy

What Matters Before You Choose a TPM For Dual Axle Trailer

Key buying criteria so you get the right fit the first time.

01
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.
02
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.
03
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.
04
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.
05
Theft protection
Taimster 10-Sensor includes anti-theft locking nuts. A tandem parked at a campground is a target. Look for locking nuts.
