Tyre modal testing is frequently used for validation of numerical tyre models and identification of structural tyre model parameters. Most studies deal with the case of a tyre fitted to a rigidly mounted rim and focus primarily on in-plane dynamic behaviour. Here, an identification method of in-plane tire dynamics is developed for the case of a free tyre-rim combination. This particular case is important when the aim is to construct a full tyre model from modal testing, capable of predicting ride and NVH phenomena involving the whole vehicle. Key attributes of the proposed approach include ease of implementation and efficient processing of measurements. For each type of excitation, i.e. radial and tangential, both radial and tangential responses are recorded. Compounding of the corresponding radial/tangential eigenvectors results in smooth mode shapes, which are found to agree with those published in other analytical and experimental studies.
