HOW DOES AN AUTOMATIC TRACTOR TIRE INFLATION SYSTEM WORK?

Central Tire Inflation System uses sensors, valves and a control unit to determine your optimal tractor tire pressure for the terrain and improve your driving conditions. The system then activates valves to inflate or deflate tires accordingly.

Drivers, you will be able to adapt tire pressure on the move and optimize your ag equipment performance from the comfort of your seat.

Central Tire Inflation System : How does it work ?

WHAT ARE THE ADVANTAGES OF THE CENTRAL TIRE INFLATION SYSTEM (CTIS)?

As farmer, change tire pressure on move is a MUST to have

ADJUST YOUR AG TIRE PRESSURE AT ANY TIME FROM YOUR DRIVERS SEAT

In many agricultural applications, changing tire pressure several times throughout the day is ESSENTIAL.
Several factors impact optimal tractor tire pressure: vehicle type, load, pressure, and speed.
As a farmer, you may have to change the pressure several times on your farm, depending on the crop.
With the Central Tire Inflation System (CTIS) you can control the pressure from your seat.

INCREASE YOUR PRODUCTIVITY, REDUCE YOUR COSTS, PROTECT YOUR SOIL AND DECREASE WHEEL SPIN

Use the right tires and services to boost your productivity

CTIS: Increase your productivity

Increase your productivity

Up to 4% increase in productivity due to improved traction*

Increase traction for less slippage, increase working time and reduce fuel consumption

Improve your savings: fuel consumption, tire longevity...

CTIS: Reduce your cost

Reduce your costs

Up to 10% fuel savings in field use when adjusting your tire pressure*

The increased surface area of the tire generates less soil pressure, avoiding compaction and preserving the maximum potential of crop yield.

Increase the yield from your field

CTIS: Protect your soil

Protect your soil

Up to 33% decrease in the pressure applied to soil when adjusted pressure is used**

Better pressure management generates less tire wear, less fuel consumption and less working time, allowing you to get better use out of your machine.

Reduce soil compaction to our services and tires

CTIS: Decrease wheel spin

Decrease wheel spin

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

Don't let a rainy season decrease your output. With CTIS, inclement weather delays are a thing of the past.

Thanks to the CTIS (Central Tire Inflation System), you can enjoy these benefits on demand from the driver's seat!

THESE FARMERS HAVE BEEN CONVINCED BY CTIS***

Equipment is becoming heavier, faster and more powerful. Fields are farther apart. Roading needs higher pressures to deal with the heat, weight and speed, while field work requires the lowest possible pressure to ensure maximum traction and minimal ground pressure. Being stuck at one pressure generates disadvantages - learn how CTIS can help you.

WHY SHOULD I ADJUST MY TRACTOR TIRE PRESSURE?

Increase the yield from your field

Protect your soil

INCREASE CROP YIELD

On farms, repeated passes by ag equipment creates soil compaction, reduction capacity for aeration, infiltration and root nutrient penetration. The economic impact of soil compaction is significant: reduced crop yield, possible disease development and decompaction of soil.

Reduce soil compaction tanks to our services and tires

Limit Soil Compaction

LIMIT SOIL COMPACTION

It's essential to adopt lower pressure in your fields to reduce the ag equipment footprint, decrease rut formation and limit compacted soil.

Improve your savings: fuel consumption, tire longevity...

Reduce your cost

IMPROVE SAVINGS

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

IS THE CTIS SYSTEM SUITABLE FOR MY TRACTOR AND IMPLEMENTS?

Central Tire Inflation System (CTIS) is compatible with all your ag equipment: fertilizer tankers, manure spreaders, planters and other implements.

CTIS will fit:

  • Any farm vehicles
  • Any tractor tire brand or range
  • Any configuration
Central Tire Inflation System (CTIS) is compatible for all your agricultural machinery


​​​​​​HOW DOES THE CENTRAL TIRE INFLATION SYSTEM CONNECT TO MY TRACTOR?

All CTIS components for implementation on a tractor

Central Tire Inflation System components schema

CTIS is composed of:

  1. one central control system
  2. one rotary union by wheel
  3. air lines to link CTIS case and each tire
  4. one connection between CTIS and the terminal (ex: Isobus) in your cab
  5. one connection between CTIS and your tractor air system

Set up of your ag equipment will be handled by a professional expert partner. For a comprehensive look at CTIS including technical information, download our product information guide.

WHAT SPECIFICALLY CAN I CONTROL FROM THE DRIVER'S SEAT?

Interface to manage your farm tire pressure

ISOBUS terminal example

The interface on your CTIS terminal is very easy to manage:

  • Quickly inflate or deflate tires, even when on the move
  • Select your surface (road, field) and your load (from full to empty)
  • Choose axle
  • Set a range of high and low tire pressures per axle
  • Up to 18 different configurations can be fully integrated into the ISOBUS terminal

How much does CTIS cost? I'd like to get a custom quote for a system.

We will need some additional information to give you a quote, please contact us to proceed with your custom quote by clicking HERE.

Is CTIS compatible with all farm vehicles?

Almost all farm vehicles can be fitted with CTIS. Our main market is tractors and trailers in general, but we can fit our systems on ag equipment such as sprayers, seeders and combines.

How long does installation of a CTIS take?

Most of the time it takes between 10 and 12 hours per axle but installation will vary by ag equipment. Please contact our CTIS expert for installation advice HERE.

Will installing CTIS void any warranties related to my ag equipment?

Our system is safe based on strict quality and safety standards. Most OE brands have approved the use of CTIS on certain equipment. Please contact our CTIS expert with specific manufacturer questions HERE.

Do I need additional equipment to install CTIS?

For CTIS to work, an air compressor (such as an air brake compressor) is necessary. If your equipment isn't equipped with one, any CTIS dealer can get one for you.

Can I use CTIS if my farm vehicle is not equipped with ISOBUS?

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

What are the benefits (ROI) of CTIS?

There are many benefits associated with CTIS:

  • Reduction of consumption and time by less slippage
  • Less tire wear
  • Extended field time
  • Preservation of soil

Read more about the benefits and get details HERE.

Why do I see additional rubber (or metal) tubes on the inside/outside of the wheel?

Tubes – whether rubber or metal – on the outside of the wheel are a standard and reliable way to get air to the tire. On bar axles, we have developed an internal rotating union which makes it more discreet and easier to use with dual tires.

Can I drive during inflation or deflation? Are there any risks?

CTIS (Central Tire Inflation System) is meant to be used on demand, or "on the move,” and with no speed limit. Using CTIS while in motion is safe.
