What is


Wheel measurement device for any wheeled vehicle able to measure in real operating conditions the effective wheel plane kinematics with respect to the ground.

Designed to overcome the practical challenges of wheel based direct measurements:
• Fixing sensors to the wheel;
• Avoiding crashes with body and suspension;
• Measuring with respect to a moving reference (ground);
• Deal with real world noise and imperfections.

Enabling technology for Tire grip characterization in the real condition: combined with specific sensors it enables to know with precision interaction Forces&Moments at the contact patch.

Technical characteristics

  • Rigidly attached to the wheel
  • Ergonomic Design
  • Direct Measurements with respect to ground
  • Based on Multiple Optical Triangulation
  • Simple, Accurate and Reliable method
  • Configurable with additional sensors
  • Straightforward non-invasive testing on any vehicle.

Wom can measure:

Dynamic Wheel Kinematics with respect to the ground:

  • Inclination Angle
  • Loaded Radius
  • Tire-Road Contact Point
  • Spindle Angle
  • Tread Temperature at multiple points from constant distance
  • Caster angle*
  • Kingpin*
  • SAI angle*
  • Scrub Radius*
  • Mechanical Trail* and more….

* Optional for some suspensions
