Abstract
A method and test stand for determining tire properties of a vehicle tire which is rotatably positioned on a rim via a wheel bearing. The interior of vehicle tire is pressurized by a fluid and the vehicle tire is applied with a wheel load. The vehicle tire is accelerated to a final speed in accordance with a pre-determinable speed ramp. The vehicle tire, in accordance with a tire speed, undergoes an oscillation excitation and reacts to the oscillation excitation with an oscillation. The method includes continuously capturing an effective tire force of the vehicle tire in the wheel bearing, due to the oscillation, and creating a data set which shows the tire force over the tire speed and tire frequency, by applying a timing signal of the speed ramp to a Fourier transformation.
