Tire pressure monitoring
GUTA trailer TPMS review
Sensor count is the spec that decides whether a tire pressure monitor fits a rig, and most kits are built around a tandem axle trailer with four wheel positions. A dually tow vehicle changes that math, adding two more positions on the truck alone before the trailer is even counted.
The GUTA GT30 is built for exactly that heavier combination. This review covers what GUTA actually publishes for it, the cost of buying more sensors than a rig actually needs, and when a smaller kit in this catalog is the better fit.

What is the GUTA GT30, and what does GUTA actually publish for it?
The GT30 ships with ten external sensors and a monitor that displays up to 46 tires total across automatically switching sections for the front vehicle, front spare, trailer rear and trailer spare. GUTA publishes a pressure range up to 188 psi and a temperature range up to 185 degrees Fahrenheit, with alert modes covering high and low pressure, high temperature, fast leakage, missing sensor signal and low sensor battery. The monitor runs on a built-in rechargeable lithium battery that GUTA states lasts 12 to 14 days per four-hour charge, and drops into a power-saving mode after 15 minutes without motion.
How does the GT30 compare against the Tymate lineup it competes with?
All four of these monitor tire pressure and temperature wirelessly. What actually separates the GT30 is sensor count and the price that comes with it, not the underlying alarm logic, which is broadly similar across the category.

Every figure here is the manufacturer's own published rating. A blank is a figure the maker does not publish, and we leave it blank rather than estimating it. The rating stamped on the part you actually receive is what governs.
What does GUTA actually publish for the GT30?
GUTA ships the GT30 with 10 sensors reading up to 188 psi, built for a dually tow vehicle and a triple axle trailer monitored together.
Published standard A published, traceable figure: a standards body, a federal regulation or a manufacturer specification states it.
| Published spec | GUTA GT30 |
|---|---|
| Sensor count | 10 |
| Pressure range | Up to 188 psi |
| Temperature range | Up to 185 F |
| Sensor battery | CR2032, replaceable, up to 4 years per GUTA |
| Monitor battery | Built-in rechargeable lithium, 12 to 14 days per charge |
GUTA states the monitor battery is rechargeable but does not publish whether it is field-replaceable if it eventually fails.
What is the downside of a 10-sensor TPMS like the GT30?
The GT30 costs close to six times the Tymate TM7 entry kit, and ten sensors is more monitoring than a single tow vehicle behind a tandem axle trailer actually needs. Buying more sensors than a rig has wheel positions for is the mirror image of buying too few: it is still a cost mismatch, just in the other direction. The GT30 only earns its price on a dually and triple axle combination, which is a genuinely narrow slice of the readers this catalog serves.
The second thing worth flagging is the monitor itself. GUTA states the internal battery is rechargeable, good for 12 to 14 days per charge, but the listing does not say whether that battery can be replaced in the field if it eventually stops holding a charge, the way the individual wheel sensor batteries can.
What are the alternatives if ten sensors is more than the rig needs?
A tandem axle trailer towed behind a single rear wheel truck needs the Tymate TM7 instead, at four sensors and a fraction of the GT30 price. A triple axle trailer without a dually tow vehicle fits the Tymate TM12, six sensors at a price between the TM7 and the GT30. Only a reader monitoring a dually tow vehicle together with a triple axle trailer, or a similarly large combination, should pay for the GT30 sensor count.
What should you check before buying a 10-sensor TPMS?
Count every wheel position on the tow vehicle and the trailer together, including dually rear wheels and any spare that will actually be monitored, before choosing a sensor count. Check the trailer tire load range chart and run the trailer tire load calculator to confirm the tires are rated correctly in the first place, since a monitor on an under-rated tire still ends in the same failure, it just gives more warning first. See load range for a 10,000 lb 3-axle trailer for a worked example closer to the GT30 target rig, and compare it against a smaller kit in the Tymate TPMS review.
How we chose
We did not test this hardware in person and we never claim to. Picks are researched from manufacturer specification sheets, published towing standards, and the recurring themes in verified owner reviews. Every pick is matched to a real gross trailer weight rating, a real tongue or pin weight rating, a real receiver size or a real load index rather than to a price bracket, and it is placed in the tier where its published capability actually belongs. We rejected the unbranded flood that dominates the search results in several of these categories, because a weight distribution hitch, a brake controller, a trailer tire and a set of safety chains are all parts whose failure puts a loose trailer on a public road. Where a figure is towing convention rather than a published standard we label it that way, and where a manufacturer does not publish a figure we leave it out instead of estimating it.

Frequently asked questions
How many sensors does the GUTA GT30 include?
Ten sensors, built to cover a dually tow vehicle and a triple axle trailer monitored together. That is more sensors than a single rear wheel truck and a tandem axle trailer need, so smaller kits in the same category are a better price fit for that more common combination.
What pressure and temperature range does the GUTA GT30 monitor?
GUTA publishes a pressure range up to 188 psi and a temperature range up to 185 degrees Fahrenheit, both well above what a standard load range D or E trailer tire needs. The system alerts on high and low pressure, high temperature, fast leakage and sensor problems.
How long does the GUTA GT30 monitor battery last on a charge?
GUTA states the built-in rechargeable lithium battery lasts 12 to 14 days after a full four-hour charge, with a power-saving mode that engages after 15 minutes without motion. The listing does not state whether that internal battery can be replaced if it eventually degrades.
Is the GUTA GT30 worth the price over a 4-sensor kit?
Only for a dually tow vehicle towing a triple axle trailer, the combination where 10 sensors are actually needed. A single rear wheel truck with a tandem axle trailer is fully covered by a 4-sensor kit such as the Tymate TM7 at a fraction of the GT30 price.
What type of battery does the GUTA GT30 sensor use?
A replaceable CR2032 coin battery, which GUTA states lasts up to 4 years per sensor. That is separate from the monitor own internal rechargeable battery, which charges over USB-C or by the built-in solar panel and needs recharging every 12 to 14 days.
Does a 10-sensor TPMS prevent a tire failure?
No. Like any tire pressure monitor, the GT30 warns about a developing pressure or temperature problem, it does not prevent one. Correct inflation checked by hand and tires rated for the actual load still come first, with the monitor as an added layer of warning.

Researched, not professional advice. This page is compiled from published standards, manufacturer towing guides and product specifications, and owner-review consensus, not hands-on testing. Figures described as a rule of thumb are towing convention rather than published standards, and they are labelled that way wherever they appear. Nothing here overrides your own ratings. Work your payload sum before your tow rating, because payload is the limit that actually binds on most half ton trucks and nearly every SUV. Load a conventional trailer to 10 to 15 percent tongue weight and a fifth wheel to 15 to 25 percent pin weight, and never lighter: a tail heavy trailer is what starts sway. Weigh the rig loaded rather than trusting a brochure dry weight. A weight distribution hitch and a set of air bags both restore ride height and control, and neither one raises a single rating. Trailer brakes are required by state law above a threshold that varies by state, and a breakaway battery that has quietly gone flat is the normal condition of most trailers on the road.
