Project start for innovative tire pressure control in the ReProRa project
Wheel with deformation measurement technology in practical use during the preliminary tests
The ReProRa project (development of a retrofittable tire pressure regulator for mobile machinery based on a new type of sensor system for determining real process wheel loads) has been running since 1 March 2026.
Over the next three years, a system for adjusting tire pressure for retrofitting to tractors, trailers and harvesters will be developed, the core components of which are wheel load sensors.
The project consortium consists of:
- Steuerungstechnik STG GmbH & Co KG(Hilter am Teutoburger Wald)
- Angewandte Systemtechnik GmbH (Dresden)
- TUD Dresden University of Technology - Chair of Agricultural Systems Technology
The aim of the project is to develop and market tire pressure control systems with sensors to determine the wheel loads resulting from the current process. The consortium sees this as a practicable solution for making the potential of modern tire designs for energy and cost-optimized operation of tractors, their trailers and self-propelled harvesters accessible to the broad market. The permanent determination of the wheel load during operation enables the tire pressure control system to function fully automatically without operator intervention. The tire is protected against overloading and thus damage. This increases user confidence and enables maximum pressure reduction in the field. This reduces the ground pressure to the technically possible minimum and saves fuel: a win-win situation for economy and ecology.
Wheel with deformation measurement technology in the test stand
The project is funded by the German Federal Ministry for Economic Affairs and Energy as part of the Central Innovation Program for SMEs (ZIM).
A feasibility study conducted in 2020/2021, funded by the Deutsche Bundesstiftung Umwelt (German Federal Environmental Foundation), (DBU, Reference: 35510/01), preceded the project. During this study, it was demonstrated that measurable correlations exist between deformations in the wheel rim and the forces acting on the wheel.
