  • Create drag
  • Create more damage than prevent
  • Need regular maintenance
  • Can’t protect from flying rocks

Negative Impact on Fuel Economy

The extra weight of mud flaps reduces fuel economy. The mud flaps also obstruct airflow to the car’s engine, which decreases the car’s performance as well as fuel economy. If you are concerned about the amount, the mud flap gives a fairly small hit on fuel mileage, which is hardly noticeable unless you drive at triple-digit speed.

Create Drag

Drag is a concerning issue in the automobile industry. It’s a force that is applied in the reverse direction of the vehicle’s motion direction and slows down the vehicle by causing air resistance.

Hence, the vehicle requires more power to overcome this, which isn’t desirable. Installing mud flaps in the vehicle reduces the airflow around the wheels and creates an eddy current.

It increases the power consumption of the vehicle to ensure efficient airflow. Using more power means increased fuel consumption, which directly affects average miles per gallon readings.

Apart from that, drag also increases exponentially by increasing the speed proportionally.

Create More Damage Than Prevent

If you don’t install mud flaps properly, they will wipe against the wheel continuously and create debris. The debris can eventually damage the wheels and end up causing a blowout. Compared to the protection it gives against dust and debris, the damage the mud flap makes will cost you much more.

Likewise, if you place the mud flap properly, it’ll keep the vehicle’s metal parts and undercarriage rust-free. Otherwise, the mud flap itself will cause rust in the same area if it is installed in the wrong size or incorrectly.
