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.
