Tire Force and Moment Test Machine

  • Powerful SpectraPAC™ data analysis software and report system

  • High-performance data acquisition system

  • Independent slip and camber structure design

  • DFMS patented technology effectively eliminates equipment resonance

  • Unique design of safety system

  • ServoTRAC™ control system, easy to operate and maintain

  • Spindle servo motor provides powerful torque driving force

  • MKI, MKIII, MKV series models to meet different needs

TMSI OnLEVELTM tire test machine performs multiple tire tests on a realistic flat road surface for PC and LT, with computer controlled speed, load, inflation pressure, steer angle, and camber angle, while capturing tire performance data for immediate analysis. Test reports and data are immediately available upon the completion of each test using TMSI's built-in report generation system.
