The numerical procedure for hydroplaning was developed by considering the following three important factors; fluid/structure interaction, tire rolling, and practical tread pattern. The tire is analyzed by FEM with Lagrangian formulation and the fluid is analyzed by FVM with Eulerian formulation. Since the tire and the fluid are modeled separately and their coupling is automatically computed by the coupling element, the fluid/structure interaction of the complex geometry such as the tire with the tread pattern can be analyzed practically. The predictability was validated by comparing the hydroplaning simulation with the experiment on the subjects such as the water flow, the velocity dependence of hydroplaning, and the effect of the tread pattern on hydroplaning. In order to predict the streamline in the contact patch, the procedure of the global-local analysis was developed. The predicted streamline enabled us to develop the new tire pattern in a short period based on the principle; “make the stream line smooth”.

The required performances of tires have been changed with the progress of vehicle technology and surrounding environment. The vehicle industry faces the big change of the so-called “CASE”; Connected, Autonomous, Shares/Service, and Electric. The future tire may not be changed drastically compared with a vehicle, but the performances related to the environment such as rolling resistance and tire noise will be more important than before. Considering the environments surrounding tires, future passenger tires may be classified into five categories: i) Inexpensive pneumatic tire; ii) Expensive pneumatic tire with low aspect ratio which is specialized for performances such as run flat, maneuverability, riding comfort, or etc.; iii) Downsized pneumatic tire with high air pressure which drastically improves both RR and tire noise; iv) Air less tire for small and low speed mobility vehicle; v) Intelligent tire.

The design of the tire construction is a process that a part is changed, added or deleted from a tire. There is no comprehensive analytical theory for tire construction due to the complexity. But one procedure for the mechanics of tire construction is the numerical method that the finite element method is combined with the optimization method using a genetic algorithm or other techniques. The design of belt and bead construction for conventional tires, as well as sidewall, wheel construction and the structure inside a tire for run-flat tires and silent tires will be discussed in this paper.
