PTG Central Tyre Inflation Systems and Products
Our Central Tyre Inflation Systems are made up of five key components:
- Rotary unions (Maintenance free design)
- Dual-line pressure control system (Patented technology ensures minimal component wear)
- Wheel valves are installed on the wheel rims and provide ultimate protection (Safe and effective)
- Electronic controller (ISOBUS available)
- Air supply (Utilise an existing air system or an additional compressor can be supplied)
The rotary unions and the entire air system on the front and rear axles are pressurised only during an active control cycle or pressure monitoring check with the tyres protected by wheel valves on the tyre rims at all times ✔
We offer tailored Central Tyre Inflation Systems to suit all types of farm machinery, including tractors FWA and 4WD articulated with options to suit singles, duals and triples. Our product range includes kits to suit self-propelled sprayers, harvesters, loaders, trailers, chaser bins, spreaders, tow behind sprayers, air carts, planters and more.
See below for examples of products we use for your tailored Central Tyre Inflation System. For more information, please contact us.

Why install a Central Tyre Inflation System on a self-propelled sprayer?
Sprayers typically operate on narrower tyres in the most trying conditions, the use of a tyre inflation system is especially valuable. Through tyre deflection, the relatively small footprint can be significantly enlarged and the heavy weight of the tank contents distributed better reducing compaction. Optimise your tyre foot print in the paddock or on the road. Reduce tyre ruts in your paddock and on your tramlines and enjoy better operator comfort.
✔ Reduce tyre wear by up to 20%
✔ Reduce fuel consumption by up to 15%
✔ Increase traction by up to 30%
✔ Helps minimise deep ruts and damaging ground compaction
✔ Better crop recovery after wheel traffic
Consider installing a Central Tyre Inflation System from PTG before investing in a second set of sprayer tyres! We can help you identify your tyre foot print increases from simple adjustments of tyre pressures.
Tractors with Flange Axles:
AIRBOX/Drive 2L dual line Central Tyre Inflation System
- Dual-Line routing on the outside of the passing the wheel (also compatible with RDS/Radial Bar axle system)

- Push button tyre pressure control while on the move
- Digital and ISOBUS control available
- Use an existing air brake system or additional compressor options are available
Why install a Central Tyre Inflation System on my tractor?
Tractors are required to operate at high road speeds while pulling/carrying varying loads and implements. In the paddock, tractors encounter varying soil types along with wet and dry conditions. The only true way to optimise your tyre foot print while maximising machine efficiency in the paddock or on the road is with a Central Tyre Inflation System due to the need for tyres to be soft in the paddock and hard on the road.
✔ Reduce tyre wear by up to 20%
✔ Reduce fuel consumption by up to 15%
✔ Increase traction by up to 30%
✔ Helps minimise deep ruts and damaging ground compaction
✔ Increases yield potential
A Central Tyre Inflation System installed on a FWA tractor can give you increased versatility matched with exceptional pulling power without the maintenance cost of tracks. Consider installing a Central Tyre Inflation System from PTG to optimise your tractor tyre foot print. A reliable alternative to tracks!
Tractors with Bar Axles:
RDS/Radial 2L dual line Central Tyre Inflation System
- Dual-line tyre regulation system suitable for tractors with bar axles
- Patented Internal rotary union no external lines (suitable only for bar axles)
- Push button tyre pressure adjustment on the move
- Can be used in conjunction with Airbox Drive 2L completing the system for tractors with front flange axles + rear bar axles)
- ISOBUS control along with various compressor options available
- Improved operator comfort
- Low maintenance (alternative to tracks)
Why install a Central Tyre Inflation System on my 4WD tractor?

Trailed Equipment Central Tyre Inflation System suitable for non drilled axles:
AIRBOX Drive 2L dual line system for trailers, air carts, sprayers, spreaders, planters and more
- Dual Line routing on the outside of passing wheel
- Easy retro fit available
- Detachable lines, parking couplers, and telescopic tubes for ease of machine servicing, storage when not in use and working environments
- If the system is intended for large volume tyres, it is usually recommended using an additional air supply system. We offer various air supply systems that turn on and off automatically as needed
Why install a Central Tyre Inflation System on my equipment?
Correctly adjusting your tyre pressures will simply reduce the rolling resistance of your equipment in the paddock or on the road, thus reducing tyre wear and fuel consumption. In the paddock, the axle weight of the equipment can also be spread across an increased tyre footprint, reducing the negative effects compaction has on your soil health and yields.
✔ Reduce fuel consumption of the pulling tractor and in some cases reduced the HP requirement to pull the implement
✔ Minimise deep ruts and damaging ground compaction
✔ Improved flotation
✔ Reduce tyre wear by up to 20%
✔ Increases yield potential
Trailed Equipment Central Tyre Inflation System suitable for pre drilled axles:
RDS 2L dual system for pre drilled axles trailers, air carts, sprayers, spreaders, planters and more
- Proven and reliable system
- Unique rotary union design (virtually maintenance-free thanks to its high-quality rotary seals and ball bearings being provided with a special lifetime grease filling)
- Requires suitable axles for installation
- If the system is intended for large volume tyres, it is usually recommended using an additional air supply system. We offer various air supply systems that turn on and off automatically as needed

Air Supply Systems:
S1000 Air Supply System (800-1000L/min)
The hydraulically powered S1000 air supply system is compact and cost effective. This system is simple to install and can be installed
on all makes of tractors or machines where the existing air supply system is insufficient.
- The S1000 air supply system provides effective air flow of
800-1000L/min at 2 bar back pressure - Only requires approximately 35L/min of hydraulic oil flow
- Load sensing options available
- Safety features such as thermal cut out as standard
K3000 Air Supply System (3200L/min)
The hydraulically powered compressor K3000 is primarily used for vehicles/implements with high air demand depending on the number and size of the tyres and/or a short inflation time is required (e.g. tandem and three-axle slurry tankers).
