Central Tyre Inflation System (CTIS): adjust your agricultural tyre pressure on the move

In agriculture, using the correct tyre pressure in the field is essential to reduce your equipment's footprint and limit soil compaction. On the road, higher tyre pressure helps ensure safe handling, reduce fuel consumption and extend tyre life.

With the Central Tyre Inflation System (CTIS), you can manage your tyre pressure and enjoy these benefits directly from the driver's seat.

Summary


Contact a CTIS expert

How will automatic tractor tyre inflation system work?

The Central Tyre Inflation System uses sensors, valves and a control unit to determine the optimal tyre pressure for the terrain. The system then activates the valves to inflate or deflate the tyres accordingly.
You can adapt tyre pressure on the move and optimise vehicle performance directly from the driver's seat.

What are the advantages of the Central Tyre Inflation System (CTIS)?

Adjust your tyre pressure at any time from the driver's seat

In many agricultural applications, adjusting tyre pressure several times throughout the day is essential.
Several factors affect the optimal tyre pressure, including vehicle type, load and speed.
As a farmer, you may need to adjust tyre pressure several times throughout the day, depending on the work you are carrying out.
With the Central Tyre Inflation System (CTIS), you can control tyre pressure directly from the driver's seat.

Increase your productivity, reduce your costs, protect your soil and reduce wheel slip

With the Central Tyre Inflation System (CTIS), you can enjoy these benefits on demand from the driver's seat.

  • Increase your productivity

    Up to 4% increase in productivity through improved traction*

    Increased traction and reduced wheel slip can improve productivity and reduce fuel consumption.

  • Reduce your costs

    Up to 10% fuel savings during field use when adjusting your tyre pressure*

    A larger tyre footprint reduces pressure on the soil, helping to limit compaction and protect crop yields.

  • Protect your soil

    Up to 33% reduction in pressure applied to the soil when the correct tyre pressure is used**

    Better tyre pressure management can reduce tyre wear, fuel consumption and working time, helping you get more from your machinery.

  • Reduce wheel slip

    Up to 30% reduction in traction loss when using CTIS*

    CTIS can help maintain traction in challenging conditions, helping you stay productive when conditions deteriorate.

Why should I adjust my agricultural tyre pressure?

  • Increase crop yield

    On farms, repeated passes by agricultural equipment can cause soil compaction, reducing aeration, water infiltration and the ability of roots to access nutrients. Soil compaction can have a significant economic impact through reduced crop yields and additional soil management requirements.

  • Limit soil compaction

    That's why it's essential to use lower tyre pressures in the field to reduce your equipment's footprint, limit rut formation and reduce soil compaction.

  • Improve savings

    No matter your vehicle type, the correct tyre pressure is essential to guarantee good behavior on the road. This will help limit rolling resistance, reducing your fuel consumption and optimise your tyre longevity.

    Whatever your vehicle type, the correct tyre pressure is essential for good handling on the road. It can also help reduce rolling resistance and fuel consumption while extending tyre life.

Is CTIS suitable for my tractor and implements?

The Central Tyre Inflation System (CTIS) is compatible with a wide range of agricultural machinery, including fertiliser tankers, manure spreaders, planters and other implements.

CTIS will fit:


  • Almost any agricultural vehicle

  • Any tyre brand or range

  • Any configuration

How does the Central Tyre Inflation System connect to my tractor?

CTIS consists of:


  1. One central control system

  2. One rotary union per wheel

  3. Air lines connecting the CTIS unit to each tyre

  4. One connection between CTIS and the terminal (e.g. ISOBUS) in your cab

  5. One connection between CTIS and your tractor's air system

What can I control from the cab?

The interface on your terminal is easy to use:


  • Quickly inflate or deflate tyres, even when on the move

  • Select your surface (road or field) and load (from full to empty)

  • Choose the axle

  • Set a range of high and low pressures for each axle

  • Up to 18 different configurations

Can be fully integrated into an ISOBUS terminal

Almost all agricultural vehicles can be fitted with CTIS. While tractors and trailers are the most common applications, our systems can also be fitted to sprayers, seeders and combines.

Installation typically takes between 10 and 12 hours per axle, although this varies depending on the equipment. Please contact our CTIS expert for advice on installation.

Our system has been developed to meet strict quality and safety standards. Most OE brands have approved the use of CTIS on certain equipment. Please contact our CTIS expert if you have questions about a specific manufacturer.

CTIS requires an air compressor, such as an air brake compressor, to operate. If your equipment doesn't have one, a CTIS dealer can supply one for you.

No problem. We offer an alternative digital solution to help you manage CTIS on your equipment.

CTIS offers several potential benefits, including reduced fuel consumption, less wheel slip and improved productivity. Better tyre pressure management can also help reduce tyre wear and protect the soil, which can help support crop yields. Find out more about the benefits of CTIS above.

Tubes, whether rubber or metal, on the outside of the wheel provide a standard and reliable way to supply air to the tyre. On bar axles, we have developed an internal rotating union that provides a more discreet solution and makes the system easier to use with dual wheels.

The Central Tyre Inflation System (CTIS) is designed to be used on demand, including while the vehicle is in motion.
