  • Tire Force and Moment Measurement
  • Tire Characterization for use in tire models
  • Time-History Simulation
  • Vehicle handling assessment utilizing hybrid simulation

Test Specimens

  • Passenger Car Tires
  • Light Truck Tires
  • Heavy Truck and Bus Tires
  • Motorsports Tires
  • Motorcycle Tires

Test Standards

  • TIMe I and II
  • SAE J1106
  • J1987_199801
  • J1988_199408
