Tires are actually extremely complicated products. Understanding where the defect in a tire is requires a very detailed knowledge and understanding of how tires are designed, how they are manufactured, and what the various sub-components are.
Tire companies fight these cases extremely hard, and unless you have an intimate knowledge of tire design, you are going to get railroaded in discovery. It is just too easy for tire manufacturers to take advantage of the complexity of the product, and the ignorance of the plaintiff’s counsel. As a result, it is possible to miss the important information in discovery that the tire was in fact defectively designed. Having counsel with extensive experience in litigating tire defect cases is absolutely essential.
