Indoor testing of tires in wet conditions: a comparison study

Indoor tire testing facility developments offer the opportunity to accurately measure the tire response in wet conditions in the laboratory. Tire specifications of different sizes and constructions have been recently tested under comparable conditions. The results of these tests are analyzed, making use of both physical and semi-empirical models. Moreover, the measurements are used to identify the parameters of the recently developed wet module extension of the MF-Tyre/MF-Swift model. This model is applied in vehicle dynamic simulations to study the effect of wet road tire behavior on vehicle dynamic performance.
