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.

- 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.

- 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.
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.
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.
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.
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.
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.
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.

Premium Range vs Budget Range
- Premium range

- Budget range
- Lower cost, often reads to 108 psi. B-Qtech 8-Set, AUTOSIRS 8-Set, SYNJAUPO 8-Set and Avutrel 8-Set fit here.
Most buyers with high-pressure tires should default to the GUTA GT20 8-Set, and choose a budget set only after checking range.

|---|---|
| Large 7 inch screen, lowest cost | SYNJAUPO 8-Set |
| Compact magnetic mount | B-Qtech 8-Set |
| Adjustable display orientation | GUTA GT20 8-Set |

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.
