What’s That Car Part Above the Tire Called? Understanding Wheel Well Trim and Fender Liners

I don’t know the name of the part but it’s above and around the tires and covers behind the headlight. About 6 months ago, I was driving and the front left tire part starting coming apart. I noticed a sound and so I pulled over and it was loose and so I snapped it back into place and didn’t think anything of it. Well, last night driving on the freeway and I heard a loud noise. Thought I blew a tire. Sure enough, it was the same piece but this time, half of it was gone. The half covering behind the headlight was gone and I could see wires. The back half was loose and I noticed some bolts missing.

Well, I was able to get it to where it was driveable to get home. After some inspection, I noticed that the front right side has nothing covering it. The back 2 tires are covered. I bought this car salvaged so I assume the previous owner crashed it and it was poorly fixed or this just came loose over time. I have never had the problem with hearing any noise on the right side so I am thinking I bought the car with the right side completely bare of any plastic or whatever covering. I did see some bolts leftover though so I used those for the left side which has half of the covering still there. What is this called and do I need to have it replaced? I have been driving for 2 years now without the covering on the front right side. The previous owner obviously wasn’t 100% honest with me and it’s also my fault for not inspecting the car enough. Do you even know what I am trying to describe? I don’t know what it’s called other than it’s plastic like and is above all 4 tires, well, it’s supposed to be anyway.

You’re describing a common car part that many people might not know by name until something goes wrong! The “Part Of The Car Above The Tire,” especially the section that extends around and sometimes behind the headlight, is likely the wheel well trim or fender liner. Sometimes also referred to as an inner fender, or splash shield, this component plays a more important role than just aesthetics. Let’s break down what this part is, why it’s important, and what you should do about your situation.

Identifying the “Part of the Car Above the Tire”: Wheel Well Trim and Fender Liners

When you mention a plastic-like covering above and around your tires, particularly one that extends behind the headlight, you’re most probably talking about the fender liner or wheel well trim. These terms are often used interchangeably, although “fender liner” typically refers to the inner, protective plastic piece within the wheel well, while “wheel well trim” can sometimes describe exterior decorative pieces as well. In your case, based on your description of it being behind the headlight and covering wires, it is almost certainly the fender liner.

These are usually made of durable plastic or composite materials and are designed to fit snugly within the wheel well, which is the space around your tires within the fender.

The Crucial Role of Fender Liners

The fender liner, this “part of the car above the tire,” serves several critical functions for your vehicle:

  • Protection from Debris: Road debris like stones, salt, water, and dirt are constantly kicked up by your tires. Without a fender liner, these materials would directly bombard the vehicle’s undercarriage, wiring, and engine components. The liner acts as a barrier, preventing damage and corrosion.
  • Preventing Water Damage: Fender liners are designed to channel water away from sensitive areas. This is particularly important in protecting electrical wiring, brake lines, and preventing rust in the wheel well and surrounding body panels. You mentioned seeing wires when your liner came loose, highlighting this protective function.
  • Aerodynamics and Noise Reduction: While perhaps less obvious, fender liners can contribute to the vehicle’s aerodynamics by smoothing airflow around the wheels. They can also help reduce road noise and vibrations that enter the cabin, contributing to a more comfortable ride.
  • Structural Support (in some cases): In some vehicle designs, the fender liner can add a degree of structural support to the fender and surrounding body panels.

Addressing Your Loose and Missing Fender Liner

It sounds like you’ve experienced firsthand what happens when this “part of the car above the tire” malfunctions. Let’s address your specific situation:

  • Loose and Missing Parts: Your initial experience of snapping the liner back into place suggests that the mounting points or fasteners were already weakened. The fact that it came loose again and now pieces are missing indicates a worsening problem. Missing bolts are a clear sign of this.
  • Front Right Side Completely Bare: Discovering that the front right side has no liner at all is concerning. If you bought the car salvaged, it’s highly likely that the original liner was damaged in an accident and never properly replaced. Driving for two years without it on one side exposes critical components to damage.
  • Do You Need to Replace It? Yes, absolutely. Driving without a fender liner, or with a damaged one, leaves your vehicle vulnerable to significant issues over time. While you’ve driven for two years without the right side liner, this doesn’t mean it’s not important. It’s likely just a matter of time before problems arise from the constant exposure to road debris and moisture.

Recommendation

You should definitely replace the missing and damaged fender liners. Here’s what you should do:

  1. Identify the Exact Part: While “fender liner” or “wheel well trim” is a good general term, for accurate replacement, you’ll need to know the specific part name and number for your car’s make, model, and year. You can usually find this information in your car’s owner’s manual, by contacting a dealership with your VIN (Vehicle Identification Number), or by searching online auto parts websites using your car’s details.
  2. Inspect for Damage: Check the areas behind where the fender liner should be for any signs of damage or corrosion from prolonged exposure. Address any rust or damage you find.
  3. Replacement: You have a few options for replacement:
    • DIY Replacement: Fender liners are often relatively straightforward to replace yourself, especially if the mounting points are still in good condition. You’ll likely need basic hand tools. You can find replacement liners online or at auto parts stores.
    • Professional Installation: If you’re not comfortable with DIY car repairs, or if there is damage that needs professional attention, take your car to a trusted mechanic or body shop. They can ensure the correct part is installed properly and address any underlying issues.

Ignoring a missing or damaged fender liner might seem like a minor issue, but it can lead to more significant and costly repairs down the road. Protecting your vehicle from road debris and water is essential for its longevity and reliability. Replacing this “part of the car above the tire” is a worthwhile investment in your car’s health.
