ADJUST YOUR TIRE PRESSURE ON THE MOVE:
Central Tire Inflation System
WHY SHOULD I ADJUST MY TIRE PRESSURE?
Importance of CTIS when planting
On farms, repeated passes by agricultural equipment creates soil compaction, reducing 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 soils.
Reduce your costs up to 10%
That's why it's essential to adopt lower pressure in your fields to reduce equipment footprint, limit rut formation and soil compaction.
Correct tire pressure is vital when farming
No matter your vehicle type, the correct tire pressure is essential to guarantee good behavior on the road. This will help limit rolling resistance, reducing your fuel consumption and optimize your tire longevity.
WHAT ARE THE ADVANTAGES OF CENTRAL TIRE INFLATION SYSTEM (CTIS)?
In many agricultural applications, changing tire pressure several times throughout the day is ESSENTIAL.
Several factors impact optimal 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.
As farmer, change tire pressure on move is a MUST to have
WHY USE A CENTRAL TIRE INFLATION SYSTEM (CTIS)?
Increase your yield up to 4%
Increase your productivity
Up to 4% increase in productivity due to improved traction*
Increased traction, less slippage, increasing working time and reducing fuel consumption.
Up to 10% fuel savings in field use when adjusting your tire pressure
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 agronomic yield to its maximum potential.
Up to 33% decrease in the pressure applied to 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.
30% reduction in traction loss with CTIS
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!
HOW DOES CTIS WORK?
HOW DOES CENTRAL TIRE INFLATION SYSTEM CONNECT TO YOUR TRACTOR?
Central Tire Inflation System (CTIS) is compatible for all your agricultural machinery, as slurry tanker, manure spreader, planter, …. You can implement it on:
- Any vehicle
- Any tire Brand or Range
- Any Configuration
Central Tire Inflation System (CTIS) is compatible for all your agricultural machinery
HOW IS CENTRAL TIRE INFLATION SYSTEM CONNECTING TO YOUR TRACTOR?
Designed and produced by our affiliated company PTG, expert more than 30 years in this technology.

CTIS is composed by:
- one central control system
- one rotary union by wheel
- air lines to link CTIS case and each tire
- one connection between CTIS and the terminal (ex: Isobus) in your cab
- one connection between CTIS and your tractor air system
CONCRETELY, WHAT CAN I CONTROL FROM MY TERMINAL IN MY CABINE?
ISOBUS terminal example
The interface on your terminal is very easy to manage:
o Quickly inflat or deflate tires, even on move
o Select your playground (road, field) and your load (from full to empty)
o Choose the axle
o Parameter a set of high and low pressures per axle
o Until 18 differents configurations
Could be fully integrated in ISobus terminal
FREQUENTLY ASKED QUESTIONS (FAQs)
Almost all Ag vehicles can be fitted with CTIS, our main market is of course tractors and trailers in general. But we can fit our systems on sprayers, seeders, combines,
Our system is a safe system 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.
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.
No problem! We offer an alternative digital solution to help manage CTIS on your equipment.
There are many benefits associated with CTIS, the most visible being the consumption and time, reduced by less slippage. Tire wear and extended field time are also. The most important is the preservation of the soil, which is an important factor for the yield. Please find details HERE.
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 duals.
Yes! CTIS (Central Tire Inflation System) is meant to be used on demand, or "on the move” and with no speed limit." Using while in motion is safe.
FEEDBACK FROM OTHER FARMERS ***
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.
