Uniformity of A Tyre

The smooth running of a vehicle as well as the wear out of different vehicle parts are influenced by the uniformity of the tyre. Today, different influences are known which can cause non-uniformity. Different measuring methods have been created to detect and to evaluate these. Radial and lateral force fluctuations, lateral force, cone and angle effects are relevant force data. True and flat running, staggering, circumference or dynamic roll radius as well as bulges and depressions are geometric measuring data.

The RGM-E machine is integrated in a production line and is designed for automatic examining where the following is determined:

  • Radial Force Fluctuation (RFF)
  • Lateral Force Fluctuation (LFF)
  • 1. – 10. Harmonic RFF (1. – 10. H RFF)
  • 1. – 10. Harmonic LFF ( 1. – 10. H LFF)
  • Lateral Force (LF)
  • Cone Effect (CE)
  • Angle Effect (AE)
  • True Running (TR)
  • Flat Running (FR)
  • 1. – 5. Harmonic TR (1. – 5. H TR)
  • 1. – 5. Harmonic FR (1. – 5. H FR)
  • Bulges and depressions
  • Dents and cuts
  • Staggering
  • Circumference
  • Dynamic roll radius
