The Dill High-Pressure Retro-Fit Trailer Tire Pressure Monitor provides real-time monitoring of four tires, including air pressure and temperature, and can be installed on most any four-wheel application. Warnings alert the driver to low- or high-pressure conditions, air leaks and temperatures changes.
The system relies on an aluminum valve stem transmitter/sensor installed in each wheel to continuously monitor pressure and temperature. This data is wirelessly sent to the vehicle’s receiver installed on the dashboard. The receiver displays the pressure and temperature for each tire position and when an abnormal condition is detected an alarm is immediately sounded and an alert icon is displayed.
The transmitter/sensor will detect tire pressures and temperatures at select intervals and transmit the data to the display regularly. As the data is received, the display will refresh. Display and sensors include external antennae to make it possible to send stronger radio signals over long distances and to receive weak signals over long distances. But to ensure proper transmission of data the distance between the display and the farthest sensor should not exceed 65 feet.
A low-pressure warning is shown if the current pressure in a tire is lower than 23psi or when 20% lower than the baseline pressure depending on custom mode selected. When current pressure in a tire exceeds 46psi or 30% higher than the baseline pressure (depending on custom mode selected), alerts will be displayed. Likewise, when the current temperature in a tire exceeds 176°F/80°C or an air leakage exceeds 6psi in 16 seconds, the driver receives a warning via the receiver display and the system will not return to normal monitoring until the problem is corrected.
This system's sensors fit in most passenger, light truck and trailer wheels that require 0.453" diameter valve stems. Please call if your wheel requires 0.625" or 9.7 mm valve sensors.

El sistema de control de presión de aire para ruedas Dill High-Pressure Retro-Fit, proporciona una verificación en vivo de las cuatro ruedas, incluyendo la presión de aire y la temperatura. Puede ser instalado en la mayoría de vehículos 4WD (Four-Wheel Drive). Las alertas notifican al conductor cuando hay presiones de aire bajas o altas, escapes o cambios de temperatura.
El sistema se basa en vástagos de válvulas de aluminio transmisores/sensores instalados en cada rueda para verificar la presión de aire y temperatura. Esta información es transmitida sin necesidad de cables al recibidor ubicado en el tablero de control del vehículo. El recibidor muestra la presión y temperatura de cada rueda, cuando se detecta una condición anormal, la alarma suena inmediatamente y un icono aparece en la pantalla.
El transmisor/sensor detecta la presión de aire y temperatura en intervalos escogidos y transmite la información a la pantalla regularmente. La pantalla se actualiza cada vez que se recibe información. La pantalla incluye una antena para recibir señales débiles y los sensores para enviar una señal más fuerte a mayor distancia. Para asegurar una transmisión correcta la distancia entre la pantalla y el sensor más lejano no debe exceder 65 pies.
Una señal de presión baja aparece, si la presión de aire es de 23psi o cuando es menos del 20% de la presión de aire seleccionada; también, si la presión excede 46psi o 30% más de la presión seleccionada; o la temperatura en la rueda excede 176°F/80°C o un escape de aire es más de 6psi en 16 segundos.
El sistema incluye:
- Una pantalla integrada LCD con una antena externa
- Cuatro transmisores/sensores con antena externa
- Un cordón eléctrico de poder
- Un montador
- Instrucciones de instalación.

Purchased for tandem axle trailer under my 20' Champion bass boat. Tow vehicle is a Ford F350 Crew Cab w/ long bed.
Overall the system works well aside from a few minor useability issues. Sensor installation in the rims (or finding a good installer) can be an issue. I had the snesors installed by Discount Tire because they also sell these. However, my local store had never installed them. I had to supervise the sensor installation in/on the rims which is esssential to proper function.
I had to utilize the extended antenna (included in the kit) for the receiver to consistently receive signal from the sensors. The extended antenna may not be needed on a shorter truck/trailer combos. My rig is longer than most typical truck/bass boat rigs.
My biggest complaint: The old-school LED dosplay is not bright enough. The pressure/temp reading is impossible to read when sun is hitting the display. You must mount the receiver/display somewhere the sun doesn't hit it which really limits flexibility.
Would also like to see a better option for surface-mounting in the dash since I will be using the system very often. The antenna jack and windshield mount connection protrudes from the back which makes it difficult for a flush mount of any kind on the face of the dash.
The display's power is supplied by a mini-USB port that is not standard in terms of power -- the TPMS display runs on a full 12v whereas mini-USB is a 5v standard. This is dangerous if you have cell-phone etc that uses standard mini-USB for charging because it will instantly fry standard mini-USB powered devices if accidentally connected. Luckily, most current cell phones, portable GPS', etc. have moved to the micro-USB interface which reduces this risk.
Other than the minor concerns above, I would give this system a 10 accross the board.

I bought this TPMS for my single axle boat trailer after experiencing what its like to lose a tire at highway speed... I hope never to relive that experience.
I opted to hard-wire the display unit to my fuse box as well as use the included long antenna. Both of those decisions were to afford aesthetic appeal. In hindsight, since towing the boat is only one of many things I do with my truck, maybe this was overkill. Anyway, it was easy to do so why not?
The unit operates as advertised, and the sensors and valve stems appeared to be of high quality. I had no trouble programming the unit to monitor @65PSI instead of its default 35PSI. Seeing the green colored number in my peripheral line of sight puts me at ease while driving, and I find myself much more relaxed while driving. Cheap insurance, for sure.
Two design decisions made me rate that factor at an 8, rather than 10. First, there is no on/off button. That means that if you're hard-wired like me, the display unit is always on. (It reads zero PSI when no trailer is in tow. Perhaps a 6 tire unit would have suited my application better? 4 sensors in the tow rig itself?) Second, there is no way to remove a tire from the display. In my single axle setup I'm using 3 sensors, the 3rd being used for the spare. Removing the unused receiver chip results in "---" being displayed, which is OK, but not perfect. For me, perfect would be if the unit just skipped over that position.
Anyway, I would buy this unit again and will recommend it to others. It's certainly of much higher quality than the kind that screw over existing valves. Customer support is also excellent. (I wrote them an e-mail to ask about a 3-tire setup before purchasing.)
Oh, I'll also add that the hardest part of the install was trying to get my trailer tires all at the same [cold] PSI. I have a compressor and a nice inflation tool with an accurate gauge, but I still found myself incessantly tweaking to get all 3 tires within 1 PSI of each other.
