The existing UATire of RecurDyn does not need the tire property file. But the GTire needs the tire property file and the property file of the UATire for the GTire entity is as follows.
Sample Files: <Install Dir>\Toolkits\GTire\RECURDYN_UA\tire_files\
Parameter definition
•UNLOADED_RADIUS: Tire unloaded radius (R1)
•WIDTH: Tire width for creating the geometry

•RADIAL_STIFFNESS: Radial stiffness (
)
•RADIAL_DAMPING_RATIO: Radial damping ratio (
)
•LONGITUDINAL_STIFFNESS: Longitudinal stiffness (
) by the slip ratio
•LATERAL_STIFFNESS: Lateral stiffness (
) by the slip angle
•CAMBER_STIFFNESS: Lateral stiffness (
) by the camber angle
•ROLLING_RESISTANCE: Rolling resistance moment coefficient
(
)
•FRICTION_MAX: Maximum friction coefficient (
)
•FRICTION_MIN: Minimum friction coefficient (
)
