Running the tyres at these higher pressure settings means that we are not using the tyre technology to its maximum and losing most of the benefits associated with the tyre design when using them in the field. Operating the tyres at high pressures in the field results in reduced traction, soil compaction and increased fuel consumption.
With our CTI system, the operator can rapidly reduce the trailer’s tyres to a field inflation level, which makes the trailer easier to tow off-road and reduces compaction, and then quickly inflate the tyres for road transport. When leaving the field, the system returns to the pre-set inflation level for the road. Higher tyre pressure on the road makes the trailer easier to pull, reduces tyre wear and again saves fuel.
We chose a single-line CTI system because it constantly monitors the tyre inflation levels and adjusts them if necessary. If, for example, you have a slow leak in one tyre, the system will maintain it at the target pressure and alert you to the fact that you have a problem.
The system has one pre-set field inflation level and one road transport inflation level. These levels are set in the factory but if the operator wants to change them, they can recalibrate the settings.
Our CTI system has a quick inflation rate; the tyres can be inflated from field pressure to a useable road pressure within 45 seconds.
Operators can start to inflate the tyres while still in the field so, when they reach the gate, the tyres are already up to road pressure.
The system has a speed sensor that automatically detects if the operator forgets to inflate the tyres when leaving the field. A built-in safety system sounds an alarm and the system automatically starts to inflate the tyres when the trailer reaches a pre-set road speed.
If the system is fitted to a two-axle trailer, the trailer is fitted with four air tanks that are filled by the tractor’s compressor. Three-axle trailers are fitted with their own hydraulically-driven compressor which inflates the tyres up to maximum road pressure even more quickly.
Our CTI system has an in-cab controller/monitor.
“Best trailers on the market… thank you so much to your team in the design office they have been so helpful in getting the designs right on this latest GX 20 CM”
“We purchased our first Stewart Trailer over 20 years ago. The quality and build of the trailers is of the highest standard and the Team are always very friendly and willing to meet individual requirements.”
“We run fifteen Stewart trailers in our busy farm contracting business. I can honestly say the trailer is smart, strong and very safe. In my eyes anyone considering a new trailer needn’t look anywhere else.”
“Undoubtedly the best trailers on the market! Unrivalled build quality, design and attention to detail with superb paint finish. Very approachable company with excellent customer care.”
“When we decided to purchase 3 Stewart Road King Trailers. The trailers have performed as he said they would, particularly their stability on steep hills. Overall great trailers and fantastic company to deal with.”
