About tyre vibration sound issues, domestic and foreign scholars have conducted a lot of researches. Existing research results show that: the road texture and tyre tread have a significant effect on the tyre/road noise. Since the road surface texture and tyre tread pattern have impact on the tyre noise, whether the coupling relationship of road surface texture and tyre tread pattern has influence on noise? In this paper, from coupling viewpoint of road surface texture and tyre tread pattern, road surface texture and tread pattern of geometric morphology were calculated by digital gray level images fractal dimension and discretized into finite element model, then the vertical contact force within contact surface of tyre and pavement, which is exciting force in tyre vibration model, last numerical calculation of evaluating noise from vibrating tyre was completed by tyres vibration model and basic principle of boundary element method for calculating sound field.
