The excitation of the tyre by short wavelength road unevennesses (e.g. cleats) is very complex. The tyre, which acts as a geometric filter due to its finite dimensions, smoothens the sharp edges of the unevenness. In this paper two situations of the tyre rolling over unevennesses are analysed using experiments and simulations: quasi-static rolling at very low velocity and dynamic rolling at high velocity. For the quasi-static rolling simulations an elaborate tyre model is used: the flexible ring model. This model is able to describe the deformation of the tyre tread-band. The responses of the tyre measured and simulated at quasi-static conditions are transferred into effective inputs. These effective inputs are used in a more simple tyre model: the rigid ring model. This model is used to simulate the dynamic behaviour of the tyre rolling over the unevennesses, also at higher velocity
