FTire Validation Example. Tire size: 195/65 R 15
Manoeuvres:
- rolling over cleats with 10 and 20 mm height, and 90o and 45o orientation, without and with camber angle
- pseudo-stationary side-slip angle sweep
Height of hub fixed; drum diameter 3.80m (exterior); blue curves: measurement, red curves: simulation.
All simulations have been performed with the same set of parameters. Measurements courtesy Daimler Research and Continental AG.
