Central Tyre Inflation Systems: A History of Innovation

Central tyre inflation systems, also known as tyre pressure control systems, were created in the 1940′s to increase the mobility of military vehicles on weak, poor traction surfaces, such as desert sands.

These days central tyre inflation systems are particularly useful for forestry truck and trailer units.

Since 1994, Bigfoot Equipment Ltd has been proudly leading the development of central tyre inflation systems for use around New Zealand and further abroad.

Here’s what we’ve proudly achieved so far to help truck drivers like you.

1994 – First New Zealand System Fitted

The first commercial system fitted was a pneumatically controlled system fitted to an LW924 Kenworth operated by Fearon Logging at Masterton.


1995 – First Electronic System Fitted

The first New Zealand-made electronic system was fitted to Owen Anderson’s truck at Whakatane.


1996 – Exported to Australia

The good word spread and the first New Zealand-made systems were fitted in Australia. G&R Logging and Moreland Holdings of Mount Gambier fitted two systems each.


2001 – Tripled Union Life

We became the first and only Central Tyre Inflation Manufacturer in New Zealand to make its own mechanical sealed rotating unions. This allowed us to fit a shield to provide added protection for the bearings, tripling the life of the unions. This also gave us the components to re-condition and modify the existing rotating unions already in service.


2002 – Version 2 Control Box

We built pressure sensors mounted on printed circuit boards. One pressure sensor is used to monitor the tyre pressures, the other pressure sensor measures the truck’s air system pressure providing protection for the brake system.


2006 - Multi Zone Control Box

The Multi Zone control boxes allow for the tyre pressures in the steer tyres, drive tyres and trailer tyres to be controlled using a single control box.


2009 – GPS Speed Sensed System

Another first in central tyre inflation technology for us. Prior to using GPS, the speed signal had to be obtained from the vehicle system.


2009 – Low Height Mechanical Sealed Union

The design of the rotating union was changed to reduce the height of the rotating union. This design also allowed for special unions to suit vehicles fitted with hub reduction differentials, and low height trailer unions.


2010 – Slimline Box Mounting

The Slimline Box mounting was developed to suit the U.K. market where central tyre inflation has to be fitted to very short wheelbase tractor units.
