Maximum Mobility on Any Terrain.


“My drivers need a system that will alert them of potential tire problems, like minor punctures or leaks, while also working to improving stability and tire wear.”

Central Tyre Inflation Systems (CTIS) maximize vehicle mobility and performance in demanding terrain and conditions, by adjusting the tyre pressure to improve traction, eliminate tyre leak and reduce soil compaction. This gives the driver complete control over a vehicle from inside the cab. . Microprocessor-based control center receives driver input from the DDM. Option to communicate to the drivetrain to optimize vehicle performance. Supports industry standard diagnostic tools. Provides operator selections for terrain and can be configured to optimize tire pressures based on axle loads. Has ability to adjust engine speed, transmission shifting, ABS, and axle differential locks. J1587 and J1939.

The Spicer® Central Tire Inflation System (CTIS™) has an automatic emergency mode to handle leaks, and it allows drivers to adjust tire pressure to optimum levels based on vehicle load – for increased traction, longer tire life, and reduced fuel consumption.

With the press of a button from inside the cab, Spicer® CTIS™ technology maximizes vehicle mobility by adjusting tire pressure to the optimum footprint on any terrain. Whether in the field or at a construction site, Spicer CTIS technology promotes confidence whether driving at highway speeds on paved surfaces, unpaved surfaces, or off-road. CTIS systems provide:

Control Tire Inflation Off-Highway with CTIS Technology.

Flexibility was a key factor in designing the Spicer® Central Tire Inflation System (CTIS). Its various setting options enable users to adjust tire pressure to the optimum level based on vehicle load, terrain type, and application. CTIS technology also makes it possible to free a stuck vehicle or take on grades and other extreme conditions that previously required assistance, as CTIS technology allows vehicles to function with extremely low tire pressures. Convenient push-button operation allows for optimum pressure selection, and integrated diagnostics alert drivers of potential tire problems and system status.

CTIS technology is used by the military to keep soldiers safe, helping them escape threats and navigate difficult terrain.

In military applications vehicles, this innovative system enables a vehicle to escape threats, bringing soldiers to safety in the most strenuous environments. It is one more way that Spicer products help serve the brave men and women who keep us safe.
