6 Best 8 Sensor RV TPMS in 2026: A Practical RV Guide

Eight-sensor RV TPMS kits for a truck and tandem trailer or a motorhome and toad: GUTA, B-Qtech, SYNJAUPO and others compared by range and display.

By Hardcastle's RV Editors

10 min read6 products evaluated

Eight sensors is the size that covers a pickup plus a tandem trailer, or a motorhome with single rear wheels plus a four-tire toad. The six kits here all ship eight sensors, so the choice is about range, display and how the kit handles switching between a solo vehicle and a combination.

Some listings offer a 4-wheel mode for solo driving and an 8-wheel mode for towing, which cuts false alerts. Each entry states what the listing says about range, modes and signal, and where it is silent.

How We Built This Shortlist

Each pick was assessed across 5 criteria weighted for real-world use.

Sensor and tire count
We compared how many tires each display handles beyond the eight sensors.
Pressure range
We compared stated psi maximums against typical RV tire pressures.
Mode options
We noted 4-wheel and 8-wheel modes and spare tire support.
Signal support
We checked stated ranges and boosters.
Display and power
We compared screen size and charging.

What Matters Before You Choose an 8 Sensor RV TPM

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

  1. What eight sensors cover

    Eight sensors cover a pickup with four tires and a tandem trailer with four. A motorhome with duallies needs more. Count the tires on every vehicle you want on one screen.

  2. Pressure range

    Heavy RV tires often run above 100 psi, and several eight-sets stop at 108 psi. The GUTA GT20 8-Set reads to 188 psi and the SYNJAUPO 8-Set claims up to 188. Check your tire's maximum cold pressure.

  3. 4-wheel and 8-wheel modes

    A mode switch lets the display ignore trailer sensors when you drive solo, which cuts false alerts. The B-Qtech 8-Set and SYNJAUPO 8-Set list these modes. Check for mode language on the listing.

  4. Spare tire support

    Spares can go flat unnoticed. The GUTA GT40 8-Set lists two spares and the B-Qtech 8-Set lists two spare sensors. Look for spare support if you carry one.

  5. Signal range and booster

    A 36 ft stated range, as on the GUTA GT40 8-Set, may fall short on a long rig. The SYNJAUPO 8-Set includes a booster. Check the stated range and booster.

  6. Screen size

    A 7 inch screen is easy to read, while a 3.15 inch screen is compact. The Avutrel 8-Set and SYNJAUPO 8-Set use 7 inch screens. Pick what fits your dash.

For a Pickup and Tandem Trailer Specifically

Look for
Eight sensors and a mode that handles solo driving, such as the B-Qtech 8-Set, or a display with room to grow like the GUTA GT20 8-Set.
In this comparison
The B-Qtech 8-Set switches between 4-wheel and 8-wheel modes, and the GUTA GT20 8-Set displays up to 24 tires.

When to Spend More

Spend more if
Spend more on the GUTA GT20 8-Set for the 188 psi range and 24-tire display, or the GUTA GT40 8-Set if you carry two spares.
Save if
Save with the SYNJAUPO 8-Set for a large screen and booster, or the B-Qtech 8-Set for mode switching.

Before You Bring One Home

Is eight sensors enough for a truck and trailer?

For a pickup with four tires and a tandem trailer with four, yes. Duallies or a triple-axle trailer need more, and the GUTA GT20 8-Set can show up to 24 tires.

What mistake do buyers make?

Ignoring pressure range. The B-Qtech 8-Set and AUTOSIRS 8-Set stop at 108 psi, which is below many RV tires.

Is the GUTA GT20 8-Set worth it over the B-Qtech 8-Set?

For tires above 108 psi, yes. For lower pressures, the B-Qtech 8-Set costs far less and adds mode switching.

How do I set up eight sensors?

Install the sensors on valve stems, pair the positions on the display and confirm readings. Switch to 4-wheel mode when you drive without the trailer if the display offers it.

How do I maintain them?

Check batteries and sensor seals at tire service, keep the solar panel clean and update thresholds after changing tires.
