Is it possible that you take your vehicle's tires for granted? Perhaps you think of them as nothing more than "donuts" which are carved from a single solid piece of rubber.

If we explore the manufacturing process of tires, we can better appreciate a tire's complexities, and can better understand why some tires cost more and perform better.
