Systems and methods for determining the contact patch parameters of a tire while rolling on deformable surfaces, such as during a hydroplaning event, are provided. More particularly, a piezoelectric sensor configured to provide a piezoelectric sensor output signal indicative of the time-varying curvature of a rolling tire can be mounted in a tire. The piezoelectric sensor output signal can be analyzed to detect a signal perturbation corresponding to the hydroplaning event. One or more characteristics of the contact patch during the hydroplaning event can be analyzed based on the signal perturbation. For instance, a parameter indicative of the shape of the contact patch during the hydroplaning event can be assessed based on the signal perturbation.
