Central Tire Inflation System (CTIS) Solutions

Our New Product Line

Precise, on-the-go tire pressure adjustment — purely pneumatic, zero electronics

Through our partnership with Ti.Systems, Triumph Quality Group supplies the CTIS system: a rugged, mechanically operated tire inflation solution built for trucks with prepared axles. Once activated, drivers can select from up to 8 preset tire pressures directly from the cabin — no tools, no delay.

Core advantages:

CTISr — Central Tire Inflation System, Removable

Proven, retrofit-ready pressure control for trucks and trailers

Triumph Quality Group supplies CTISr through our partnership with Ti.Systems — a rugged, field-proven system for adjusting tire pressure while the vehicle is moving. With more than a decade of real-world use in demanding agricultural and utility vehicle applications, CTISr has earned its reputation for reliability.

Its detachable, removable hose design makes it one of the most flexible systems available — suitable for virtually any truck or trailer, and especially well suited to retrofitting, since it requires no axle preparation and connects directly to your vehicle’s existing tire valves.

Core advantages:

How it works

Once activated, drivers can select from up to 8 individually preset tire pressures right from the cabin. The purely pneumatic control unit automatically brings all tires to the selected pressure, then shuts off — no manual monitoring needed. Two control system variations are available depending on your setup.

Key component — Patented Wheel Valve:

Screws directly onto the existing tire valve after the valve core is removed, delivering airflow up to 900 L/min through a wider flow section.

Built for durability:

Air lines run from the fender to the wheel hubs, connecting to compact dual-line rotary unions mounted on the rims. Purpose-built brackets keep the lines properly clear of the tires as the wheels turn. Detachable lines connect via quick-connect fittings and store in dummy couplers on the fender when not in use; removable lines detach just as easily and stow in a hose depot.

Fits: Trucks and trailers of any type — single or twin tire configurations.

STIS — Semi-Automatic Tire Inflation System

Fast, precise pressure adjustment — while parked

Supplied through Triumph Quality Group’s partnership with Ti.Systems, STIS is a purely pneumatic system for adjusting tire pressure while the vehicle is stationary. Users can dial in any pressure with the stageless version, or select from up to 8 presets with STIS preset 4|2. Once the spiral hoses are connected, the system runs autonomously — no driver monitoring required — and shuts off automatically once the target pressure is reached.

STIS comes factory-fitted on new vehicles from manufacturers like Mercedes-Benz and MAN, and retrofits easily — workshop installation or DIY.

Core advantages:

Fits: Trucks 4×4 | 6×6 | 8×8 (single|twin tires)

ATVs | SUVs | Off-road vehicles | 4×4|6×6
