Tire centrifugal contour test stand from TMX
Measure tire contour at top speed: contactless, accurate, automated
- Type: development test stand, quality assurance
- Device under test: passenger car tires
- Test task: analysis of tire contour under centrifugal force at high speeds
How does a tire change at 350 km/h? Our test stand shows you.
As speed rises, huge centrifugal forces act on a rotating tire. They stretch the material and change the contour, which can affect handling and safety. For high-speed vehicles, sports cars and lightweight electric vehicles with high torque, knowing these effects is essential.
The TMX centrifugal contour test stand delivers high-resolution contour data under real rotating conditions. Critical deformation shows up early, and designs can be optimized where it matters.
Typical test requirements
- Analysis of contour change at speeds up to 350 km/h
- Measurement at different inflation pressures and speeds
- Derivation of expansion behavior, imbalance potential and stability limits
- Validation of CAD and CAE models with real contour data
- Identification of weak points (e.g. bulging, out-of-roundness)
- Automotive
- Development
- Components

The TMX centrifugal contour test stand
Contactless contour analysis at top speed
The TMX tire centrifugal contour test stand combines a stable high-speed drive with a high-accuracy laser scanning system. An XYZ positioning system scans the surface of the rotating tire at defined speeds. The data delivers complete contour profiles for different test conditions.
Test stand mechanics
The test stand is designed for high rotational stability. The structure holds the tire safely, even at high speeds and under dynamic load.
- Massive machine bed (concrete or T-slot plate) for vibration damping
- High-stiffness shaft holds the device under test safely at up to 350 km/h
- XYZ mechanism positions the laser head (contactless scanning)
- Optional protective enclosure or extraction at high tire speeds
Drive and control
The drive brings the tire up to test speed quickly and under control. The controller handles speed control and synchronizes the measurement cycles.
- Inverter-controlled high-speed drive
- Control via real-time control CPU
- Synchronization of scanner and tire speed
- Freely definable speed points (0 to 350 km/h)
Measurement and control technology
The laser measures continuously along the tire circumference. Distances and coordinates are recorded live and displayed as contour maps.
- Laser scanner with high sampling rate for contour capture
- XYZ axis control for exact scanner positioning
- Automated measurement cycle
- Result: tire contour at every speed
- Data export for comparison with CAD and simulation data
Operating software
The guided user interface makes it easy to create, run and evaluate test sequences.
- TMX test sequence editor for measurement scenarios
- Real-time display of scan progress and speed status
- Fully automatic processing with contour map output
- Report generator for export and documentation
Summary
The TMX tire centrifugal contour test stand gives developers and test engineers a powerful tool for deformation analysis at high speed. Contactless laser technology and a dynamically stable design enable realistic contour measurements, a key building block for developing modern high-speed tires.
