What is the Cover Over the Spare Tire Called? Spare Tire Cover Terminology Explained
May
This is one of those small terminology questions that comes up constantly, especially for first-time buyers. You walk around the back of a Wrangler, a Bronco, a Land Cruiser, or a travel trailer, look at the round shell over the spare tire, and try to figure out what to search for online. Half the results call it one thing. The other half call it something slightly different. Both are usually pointing at the same product.
The confusion is mostly historical. The accessory has been around for decades, sold by everyone from off-road outfitters to RV dealers to mainstream auto parts stores. Different industries picked slightly different names. The British and American markets diverged on terminology, the way they tend to. And then customization brought a wave of new sellers who each chose their own preferred phrasing.
None of it really matters when you are shopping — you can usually find what you want with any of the common terms. But it is worth knowing which words are precise and which ones overlap with other products, so you do not accidentally buy a hubcap when you wanted a tire cover.
Here is the short, useful version.
The cover that fits over the front face of an externally mounted spare tire is most commonly called a “spare tire cover” or “tire cover.” Other accepted names include spare wheel cover, rear tire cover, and carrier cover. All refer to the same product — the protective shell that mounts over the spare on Jeeps, Broncos, G-Wagons, RVs, trailers, and other rear-spare vehicles.
The terms you will see most often
- Spare tire cover. The most common term in the US market and the one used by manufacturers, retailers, and most search results. Refers specifically to covers for the spare (rear-mounted) tire.
- Tire cover. A shorter version of the same. Sometimes also used for wheel-protection products that wrap around mounted tires on parked RVs, which are a separate product category.
- Spare wheel cover. The British and Commonwealth English version. Same product, slightly different vocabulary.
- Wheel cover. Less precise — this can also refer to hubcaps or center caps on regular wheels. Worth qualifying with “spare” to avoid the wrong search results.
Terms you will see occasionally
- Carrier cover. Emphasizes the spare-tire carrier itself — swing-out, hitch-mount, or ladder. Common in the overlanding and 4×4 worlds.
- Rear tire cover. Emphasizes the position rather than the function. Often used in RV and trailer listings.
- Spare cover. Just a shortened version of “spare tire cover.” Same product.
What it is not (so you do not buy the wrong thing)
A few products use overlapping language but are not the same accessory at all:
- Hubcaps and decorative wheel covers. These cover the rim only, not the whole tire face. If you are looking for hubcaps, that is what to search for — not “wheel cover” alone.
- Tire bags and wheel bags. Designed for transporting or storing tires, not for daily display on a mounted spare.
- RV tire sun shades. Wrap around all four of the mounted RV tires while parked, to protect from UV during storage. Not the same as the spare cover on the back of the vehicle.
Why the wording matters when you shop
If you search “wheel cover,” you will get a flood of hubcaps. If you search “tire cover,” you might get RV sun-shade sets in your results. Searching for “spare tire cover” or “spare wheel cover” narrows the results to the actual product — the protective shell that mounts over the front of the spare.
If you are shopping for a specific vehicle, adding the make and model usually filters the rest out. “Spare tire cover Jeep Wrangler” or “spare wheel cover Land Rover Defender” will land on the right pages on almost any site, ours included.
Frequently asked questions
Is “spare tire cover” the right term?
Yes. It is the most common and most precise term in the US market. Manufacturers (Wheel Shell included) and most retailers use it as the standard.
Is “spare wheel cover” the same thing?
Yes. It is the British and Commonwealth English variant. Both phrases refer to the same accessory and will get you to the same product on most sites.
My British or Australian friend calls it a “wheel cover.” Is that wrong?
Not wrong, just less specific. “Wheel cover” can also refer to a hubcap or center cap on a regular wheel. “Spare wheel cover” or “spare tire cover” is unambiguous — you will not get hubcaps in the search results.
What do dealers and parts catalogs call it?
Most US dealer catalogs list it as “spare tire cover” or simply “tire cover” under the accessories or exterior section. European catalogs lean toward “spare wheel cover.” The product itself is the same regardless of label.
