Precise tire pressure adjustment when vehicle is stationary
Adjust tire pressure while vehicle is stationary – Can be retrofitted to any vehicle – Inflate | deflate all tires simultaneously – No preperations required
Patented ti.systems tire valve!
- Screwed directly onto regular tire valve after inner valve core is removed
- Much greater section width
- Airflow up to 900l/min
- Easy to use thanks to quick coupling system
All tires simultaneously!
- Simultaneous pressure adjustment of all connected tires
- Different pressures front | rear axle(s)
- Significantly lower inflation and deflation times
Purely pneumatic!
- Hard-wearing | virtually no maintenance
- Easy to retroft at affordable cost
- No electric or electronic components
- No electromagnetic compatibility testing required
STIS | How to use
Step 1
Select the required pressure.
Step 2
Connect all hose depots to the tires.
Step 3
Tire pressure gets adjusted simultaneously in all conntected tires and system stops automatically when selected pressure is reached.
Step 4
Put back the spiral hoses into the hose depots.
STIS | control units
We offer different kinds of control units and operating units for adjusting the tire pressure. All of our boxes are manufactured using high-quality 3mm sheet steel and coated in colour shade RAL 7021 KTL*.
Hence, the inner components are optimally protected from mediums entering as well as from weather conditions.

STIS | hose depots
Our hose depots come in two different sizes: 75mm and 125mm. The depot tubes and stamped caps are manufactured using high-grade, weather-proof and UV-resistant plastics.
Moreover, we use high-grade spiral hoses made of polyamide. This allows for long lasting operation without losing elasticity and internal stress. Depending on the vehicle different extension lengths of the spiral hoses are available.

All depots of this size are equipped with size K21 plug-in couplings.
Depot length: 265mm | 290mm | 350mm
Extension length: 1500mm | 1900mm | 2500mm

All depots of this size are equipped with size K26 plug-in couplings.
Depot length: 335mm | 420mm
Extension length: 2500mm | 3500mm
ti.systems | tire valves
Our patented screw-on tire valves can be installed onto any generic tire valve size. Thanks to the substantially bigger airflow rate, the tire pressure can be adjusted up to 8 times faster compared to using conventional tire valves.
Caps are included, which protect the tire valves from dust and dirt. Gas station adaptor with regular tire valve thread (Vg8) is part of every system.

ti.systems | STIS
Time-tested for many years, the STIS allows the tire pressure to be adjusted when the vehicle is stationary. The STIS is based on a permanently fixed quick coupling system; it is connected with the vehicle’s pneumatic brake system or with one of our powerful AIR SUPPLY compressor systems so the tire pressure can be adjusted anytime and anywhere.
The user can adjust any required pressure (STIS stageless) or alternatively select between up to 8 preset tire pressures (STIS preset 4|2).
The purely pneumatic control unit guarantees trouble-free operation even in the harshest conditions.
After connecting the spiral hoses, the system operates autonomously, without the need for the driver to monitor the process. The system automatically cuts out when the correct pressure is reached.
Leading manufacturers such as Mercedes Benz and MAN have been offering the STIS factory-fitted in their new vehicles for many years now. Retrofitting is simple and can be done by any workshop or by the buyer himself.
The STIS works fast, is precise and easy to handle.
The STIS offers distinct advantages:
Precise tire pressure adjustment when vehicle is stationary
Fast and easy to operate
Simultaneous pressure adjustment of all tires in no time
Nearly no maintenance required
Easy to retrofit
Low cost
The STIS can be fitted on:
Trucks 4×4 | 6×6 | 8×8 (single|twin tires)
ATVs | SUVs | Off-road vehicles | 4×4|6×6
Any type of trailer
