Did you know?

All new passenger vehicles are required to have sensors to measure tire pressure and notify the driver of a tire with low pressure. These are called Tire Pressure Monitoring Systems, or TPMS.

Monitoring the air pressure in your RV, truck, and trailer tires is just as important! Maintaining correct tire pressure will help protect your property and increase your miles per gallon.

Here's the facts:

  • 75% of roadside flats are caused by a slow leak or under inflation
  • 250,000 accidents each year in the U.S. are caused by under inflated tires
  • 15% under inflation reduces fuel mileage by 1%

How Trailer TPMS Works:

Dill's trailer Tire Pressure Monitoring System (TPMS) is designed to be installed directly in your tires to provide accurate pressure and temperature readings. 

A warning will trigger if your pressure is 20% below or 30% above your baseline pressure. The system also gives you a high temperature alert when too much heat is building up inside one of your tires.

You have the option to set the baseline pressure as low as 20 and as high as 130 psi.

The system is available with 2 sensors, 4 sensors, 6 sensors, 8 sensors, or as many as 10 sensors.

Valve options available for 0.453", 0.625", 9.7mm rim hole diameters (0.453" is the most common and uses Dill TP-416 valve stem).

Benefits of the Dill System

  • Easy to install display with option to hard-wire or simply plug into cigarette adapter
  • Continuously updated pressure and temperature readings
  • Ability to set your own baseline pressure
  • High temperature warning
  • Unique adjustable valve design allows sensor to fit almost every rim design

Properly inflated tires will:

  • Improve vehicle handling
  • Increase fuel economy
  • Reduce tire tread wear
  • Protect important items you're towing


Internal vs. External Sensors - What's the Difference?

  • An internal sensor is mounted directly inside your tire
  • Internal sensors provide the most accurate pressure and temperature reading
  • Internal sensors have a much longer battery life than external sensors
  • An external sensor is most commonly a sensor placed inside the valve cap
  • An external sensor can be damaged by road hazards, stolen, may cause vehicle balancing issues, and can provide inaccurate readings if installed incorrectly
