That trim is usually called a fender flare or wheel arch molding, depending on the car and where the piece sits.
If you spotted a loose plastic strip over a wheel and wondered what to call it, you’re talking about one of a few closely related body parts. On many cars, the common name is fender flare. On others, it’s listed as wheel arch trim, wheel opening molding, or fender molding.
The name changes by brand, body style, and location on the vehicle. Front pieces often fall under the fender. Rear pieces may be tied to the quarter panel. That’s why one shop says “fender flare” while a dealer parts desk says “wheel opening molding.” They may still mean the same outer plastic trim above the tire.
What Is the Plastic Piece Above the Tire Called? On Most Cars
In day-to-day speech, fender flare is the name most people use. It describes the trim that follows the curve of the wheel opening and sticks out a bit from the body. Trucks and SUVs use that term a lot, since the part is often more visible and chunkier.
On sedans, hatchbacks, and crossovers, the part may sit flatter against the body. In those cases, parts catalogs often lean toward names like wheel arch molding or wheel opening molding. If the piece is thin and decorative, some brands call it garnish or molding instead.
The Names You’ll Hear Most Often
- Fender flare — common on SUVs, pickups, and off-road trims.
- Wheel arch trim — plain-language term for the curved outer trim around the wheel opening.
- Wheel opening molding — common in dealer parts catalogs.
- Fender molding — often used for front wheel-area trim.
- Quarter panel molding — often used for the rear wheel-area piece.
- Garnish — a catalog word for small outer trim pieces.
Why One Part Ends Up With Several Names
Car makers name parts by location, shape, and trim package. A black matte arch on a crossover may be sold as a flare. A body-color piece on a sedan may be sold as a molding. A slim decorative strip can be grouped with exterior garnish.
That can trip people up when they search online. The part above the tire may sound like one thing in a forum and another in a dealer diagram. The fix is simple: match the name to the exact spot on the car, then match the side, row, and trim level.
Where The Piece Sits Changes The Catalog Name
Position matters more than most people think. The plastic trim around the front wheel opening is often tied to the front fender. The rear one is often tied to the quarter panel. Same basic idea. Different catalog wording.
That’s also why a damaged rear arch piece may not show up under “fender flare” in a parts search, even if that’s what people call it. It may be buried under quarter panel trim, rear wheel opening molding, or outer garnish.
| Term You May See | Where It’s Usually Used | What It Tells You |
|---|---|---|
| Fender flare | Front or rear arch on SUVs and trucks | The trim often sticks out from the body more than flat molding |
| Wheel arch trim | Any wheel opening | General plain-language name for the curved outer piece |
| Wheel opening molding | Dealer parts catalogs | Catalog-style wording for trim that borders the wheel opening |
| Fender molding | Front wheel area | Often tied to the fender panel rather than the whole arch |
| Quarter panel molding | Rear wheel area | Used when the trim sits on the rear body section |
| Wheel arch molding | Crossovers, wagons, luxury models | Another catalog term for the same outer trim line |
| Garnish | Trim-heavy catalogs | Often a smaller decorative outer piece rather than a wide flare |
| Cladding | Off-road trims and lower body packages | May include the arch piece plus rocker and lower door trim |
OEM parts listings show this naming split clearly. Toyota uses the term Front Fender Wheel Opening Molding on some models, while Subaru uses Fender Flare. Wheel Arch Molding Kit for a similar outer arch piece.
What That Plastic Trim Actually Does
This part isn’t there just for looks. It helps catch spray, grit, and road filth kicked up by the tire. It also shields the paint edge around the wheel opening from chips and rub marks.
On trucks and trail-ready SUVs, a flare may also widen the body line around the tire. That extra lip can keep mud and small stones from blasting straight onto the side panels. On city cars, the piece is often slimmer and more about finish and surface protection.
Main Jobs Of The Part
- Protects paint around the wheel opening
- Helps block road spray and grit
- Covers seam edges or fastener areas
- Finishes the wheel arch line
- Adds width on trims with wider tires
How To Figure Out Which Piece Your Car Has
If you’re buying a replacement, “plastic piece above the tire” won’t get you far. You need the vehicle year, make, model, trim, and the exact corner of the car. Left front and right front are often different. Rear pieces can differ too, even when they look close at a glance.
- Start with the location. Is the piece above the front tire or the rear tire?
- Check the shape. Does it flare outward, or does it sit flush with the body?
- Note the finish. Black textured plastic, smooth black, or body color can point to a different part number.
- Check fasteners. Clips, screws, and tabs vary from one trim line to the next.
- Use the VIN if you can. That cuts down on wrong-order headaches.
What To Ask For At The Parts Counter
A clean way to ask is: “I need the front right wheel arch trim,” or “I need the rear left fender flare.” That wording gives the counterperson both the location and the type of part. If they use a different name in the catalog, they’ll still know where to land.
| What You Notice | Likely Part Name | What To Check Next |
|---|---|---|
| Wide plastic arch on an SUV | Fender flare | Check if it’s textured or painted |
| Thin trim above the front tire | Front fender molding | Match left or right side |
| Rear arch trim on a crossover | Quarter panel molding | Check clip pattern and trim level |
| Dealer diagram uses “wheel opening” wording | Wheel opening molding | Match the exact wheel position |
| Part is loose after a curb rub | Flare, molding, or garnish | Inspect tabs and hidden clips before ordering |
Parts People Mix Up With It
A few nearby parts get confused with this trim all the time. That can lead to wrong orders, bad search results, or a body shop quote that doesn’t match what you meant.
- Mud flap or splash guard: hangs behind the wheel, not above it.
- Inner fender liner: sits inside the wheel well, not on the outer body.
- Rocker cladding: runs along the lower side of the car under the doors.
- Bumper extension: ties into the corner of the bumper, not the full wheel arch.
If the part is visible from the outside and follows the curve of the wheel opening, you’re usually in fender flare or wheel arch trim territory. If it sits inside the wheel well, that’s a different part family.
When A Loose Or Cracked Piece Needs Replacement
Minor scuffs don’t always call for a new part. A cracked flare, missing clip, or bowed-out edge is different. Once the trim starts pulling away, water and grit can get behind it, and the piece may flap at speed or rub the tire on tight turns if it has sagged badly.
Check the mounting tabs before you buy anything. In some cases, the plastic trim is fine and only the clips are broken. In other cases, one snapped tab means the whole piece won’t sit tight again. Painted arch pieces also tend to show damage more clearly than black textured ones.
The Term Most People Need
If you want the plain answer, call it a fender flare when the piece is chunky and wraps the wheel opening. Call it wheel arch trim or wheel opening molding when you want a safer all-around term, especially for dealer parts searches.
That wording works well in a search bar, at a salvage yard, or when you’re talking to a body shop. It gives you a common name, plus the catalog-style terms that often show up on OEM diagrams. That’s the easiest way to land on the right plastic piece above the tire without wasting time on the wrong part.
