Do you know how much air is in your tires?  How about in your trailer tires? 

Most people do not!  In US all new passenger cars are required to have sensors to measure tire pressure; and other countries are likely to follow.  It is just as important to maintain the correct tire pressure in your caravan and trailer tires when you are towing.

Don’t be a statistic…

  1. 75% of roadside flats are caused by a slow leak or under inflation
  2. 250,000 accidents a year in the US are caused by under inflated tires
  3. 15% under inflation reduces fuel mileage by 1%!

Masten's tire pressure monitoring systems (TPMS) are designed to be installed directly in your car, 4x4, caravan, trailer etc tires to provide accurate pressure and temperature readings.  A warning will trigger if your pressure is below your set pressure, and you can set your desired pressure range. 

Benefits of the Masten system: 

  • Easy to install display with option to hard-wire or simply plug into cigarette adapter 
  • continuously updated pressure & temperature readings
  • the ability to set your own baseline pressure
  • high temperature warning
  • unique adjustable valve design allows sensor to fit almost every rim design

External Cap sensors are a very convenient and lower cost option. Why are internal valves better? 

  • A sensor mounted directly inside your tire will provide a more accurate pressure and temperature reading however needs to be professionally fitted
  • A cap design is DIY Install but can be damaged by a road hazard, can be stolen, may cause vehicle balancing issues, and can potentially provide inaccurate readings if installed incorrectly

Properly inflated tires will: 

  • Improve vehicle handling
  • Increase fuel economy
  • Reduce tire tread wear
  • Improve safety and protect important items you are towing


Tyre Pressure Monitor Sensor Description - this is for one sensor with frequency 433.93MHz

This listing is for one sensor for the Masten TPMS. The Masten TPMS is a Premium, High-End TPMS (Tyre Pressure Monitoring System) with color LCD display wireless.


The Masten TP-05 and TP-06 is a High Quality product which has been Designed and Made in Taiwan

The Masten TP-05 and TP-06 TPMS Kits can measure up to 87psi. The highest standard pressure should be set no higher than 69psi. (Because the first high pressure alert will start when reaches 125% of the standard pressure).

DIG Options also offer the Masten TPMS for Trucks which can measure up to 188psi. The highest standard pressure should be set no higher than150psi. This is via special order. please message us for information.



  1. Use of common valve (easily available and replaceable)
  2. Measure tire pressure, tire temperature, sensor battery level, signal strength and vehicle battery level
  3. Bi-directional (2 ways) communication on sensor.
  4. Optional TPMS Tire Sensor Diagnose Tool LF Remote Control allows you to Force sensors to transmit signals WITHOUT inflating or deflating tire pressure and learn or exchange wheel positions.
  5. Early warning of slow leaks
  6. Detects temperature changes - depends on the monitor
  7. Save on fuel comsumption

What's Included 

  1. One 433.93MHz Valve Sensor 

Why do you need a TPMS?

Optimal Driving Safety: Under-Inflated tire pressure will result in reduced vehicle stability / control ability and deformation tires, while the Over-Inflated tire pressure will increase your chances of a sudden flat tire.
Fuel Economy: With instant monitoring on the tire pressure, the TPMS device may save you up to 4% of fuel on average with proper tire pressure.
Extended Tire Life: Under-Inflated tire pressure will cause excessive tire wear by up to 50% more if the tire is Under-Inflated by 9%.
More environmentally friendly: Keeping the tire pressure at the correct pressure level can reduce CO2 emission up to 40%, helping to reduce the global warming effects.
