How to choose a GUTA TPMS

Why TPMS matters for towing

Under-inflated trailer tyres overheat, blow out, and cause sway. A TPMS warns before failure, not after, and temperature alerts catch slow leaks and dragging brakes that pressure alone misses.

Count tyres before buying

Sensor counts are fixed per kit: 4, 6, 10, or 12. Count every tyre including duals, but note spares are usually unmonitored unless you buy extra sensors. Buying the wrong count wastes money or leaves tyres blind.

Boosters for long rigs

Signal distance grows with rig length, and distant trailer sensors drop out without a booster. The GB30 booster in the 10- and 12-sensor kits exists for exactly this reason; short vehicles rarely need one.

Solar versus USB monitors

Solar monitors stay charged on the dashboard and need no cable, but they need sunlight. USB monitors work anywhere but need charging discipline. Dark storage drains solar monitors, so USB-charge before long parking.

Sensor batteries and spares

Each sensor has a battery, so more sensors mean more maintenance. Keep a spare GS02 sensor on board, since a dead sensor leaves a tyre unmonitored until replaced and paired.

Pairing and programming

Pair sensors in the maker’s stated order, label them by wheel position, and test all readings before towing. A sensor paired to the wrong position reports the wrong tyre, which is worse than no reading.

Installation basics

Fit sensors to valve stems in the maker’s stated order, label each by wheel position, and pair them to the monitor before driving. Mount the monitor where the driver can see it without looking away from the road, and mount the booster, if included, per maker placement guidance for your rig length.

Test all readings stationary, then on a short drive: every tyre should read pressure and temperature, and no sensor should drop out. If a distant sensor drops, reposition the booster before towing, since a blind tyre at highway speed is the failure this system exists to prevent.

For tyre care, see all-terrain tyres and TPMS programming tools for related guides.

Safety essentials

Never tow on a tyre the monitor cannot read; fix the sensor first.
Check pressures cold, before driving, not after heating.
Treat temperature alerts as seriously as pressure alerts.
Keep a manual gauge on board; electronics fail, gauges rarely do.
Replace sensor batteries promptly; a dead sensor is a blind tyre.
Do not ignore a slow leak alert to finish a journey.

Troubleshooting

Symptom	Likely cause	Fix
Sensor not reading	Dead battery or unpaired sensor	Replace battery; re-pair sensor
Distant sensor drops out	No booster or poor booster placement	Fit or reposition the GB30 booster
Wrong tyre reported	Sensors paired in wrong order	Re-pair in maker order; label positions
Monitor will not charge	No sunlight (solar) or dead cable	USB-charge; check cable and sunlight
Pressure reads low	Cold morning or slow leak	Check cold pressure; inspect for leaks
Temperature alert	Dragging brake or low pressure	Stop safely; inspect tyre and brake

Who should NOT buy these

Wrong sensor counts: a 4-sensor kit on a 10-tyre rig leaves six tyres blind. Count tyres first, every time, including duals.

Unboosted long rigs: distant trailer sensors drop out without a booster. If your rig is long, buy the boosted kit, not the cheapest one.

Monitor-only reliance: keep a manual gauge on board. Electronics fail, batteries die, and a gauge is the backup that never needs charging.

Ignoring alerts to finish a journey: a slow-leak or temperature alert is the warning before a blowout. Stop safely and inspect, every time.

FAQ

How many sensors does my RV need?

Count every tyre including duals: a single-axle trailer needs 4, a dual-axle 6 or 8 depending on duals, and a triple-axle rig up to 12. Spares are usually unmonitored unless you buy extra sensors.

Do I need a signal booster for my trailer?

Yes for long rigs: distant sensors drop out without one, which is why the 10- and 12-sensor GT30 kits include the GB30 booster. Short vehicles rarely need a booster.

What pressure range do GUTA sensors cover?

The GS02 sensors list 0-188 PSI with +/-1 PSI accuracy, and the M20-6 lists 0-188 PSI with +/-1.5 PSI. These are maker claims, not independently measured results.

Solar or USB monitor — which is better?

Solar suits dashboard users who park in sunlight and hate cables; USB suits covered parking and dark storage. Solar monitors still USB-charge during long dark storage.

Can I add sensors later?

Yes, with GS02 replacement sensors, but buy the right count upfront where possible: adding sensors later means extra pairing work and a possible booster need you did not plan for.

Will TPMS work on my trailer’s dual tyres?

Yes, with one sensor per tyre including inner duals, which need valve extensions for fitting. Count inner duals in your total, or they stay blind.

How long do TPMS sensor batteries last?

Per maker guidance, sensor batteries last years under normal use, but more sensors mean more batteries to track. Keep a spare sensor on board for uninterrupted monitoring.

Can TPMS prevent blowouts?

It warns before most blowouts by catching slow leaks, under-inflation, and overheating early. It cannot prevent sudden impact damage, and alerts must be acted on, not ignored.

Do I still need a manual tyre gauge?

Yes. Keep one on board as a backup: electronics fail, batteries die, and a gauge verifies the monitor’s readings when they look wrong.
