What is the name of the shield above the tire?

[Jon]

The shield above the car tire is called the inner fender liner or wheelhouse liner. It serves to block mud and dust and is installed behind the four tires of the car. The front two tire mud flaps are located on the left and right lower sills, while the rear two mud flaps are positioned on the rear bumper. Below is additional information about mud flaps: 1. Mud flaps protrude 5cm beyond the body, effectively preventing sand or particles kicked up during driving from damaging the car's paint. 2. They reduce the car's ground clearance, affecting its off-road capability. 3. The entire mud guard consists of two parts: the outer protruding part is the wheel arch, commonly black, and the inner layer is the liner panel. The mud flap is composed of the wheel arch and the liner panel, enhancing aesthetics, reducing the drag coefficient, and ensuring smoother driving.
