What is this pictured item that resides behind your tires?
Answer Mudflap
While some drivers use their mudflaps to display messages or advertise their businesses, they also serve an important function by protecting your vehicle — and the people around it — from flying debris. Most mudflaps are made out of flexible materials, but they can be fashioned out of firmer metals, too.
