Are Spare Tire Covers Legal? US, State, and DOT Requirements Explained
Mai
Every once in a while, a buyer reaches out asking whether a spare tire cover is even legal. Usually it is because they have heard a story about someone getting pulled over for an oversized cover, or they are nervous about state inspections, or a neighbor mentioned “DOT rules.” It is a fair question to ask before spending money on something that hangs visibly off the back of a vehicle.
The short version is that spare tire covers themselves are not regulated in the US. There is no specific federal or state law against covering a spare. What is regulated is anything attached to a vehicle that can obstruct license plates, brake lights, or backup cameras — and those rules apply to bumper stickers, hitch accessories, and bike racks the same way they apply to tire covers.
That said, there are a few real-world edge cases where a cover can become a problem. They are almost always avoidable with the right size and a properly placed camera hole. Once you understand which rules actually apply, the answer becomes pretty simple.
Here is the realistic breakdown of where you stand legally with a spare tire cover, and what to watch for if you want to stay out of trouble at inspection time.
Yes, spare tire covers are legal in all 50 US states and in most countries. There are no federal DOT regulations specifically against spare tire covers. The only practical legal concerns are general rules about license plate visibility, rear lighting, and functional backup cameras — all of which are easy to comply with when the cover is sized correctly and the backup-camera hole is in the right place.
Federal DOT rules that actually apply
The US Department of Transportation does not have a regulation specifically aimed at spare tire covers. What the DOT does regulate is anything that could obstruct safety equipment on the back of a vehicle:
- License plate visibility — 49 CFR 393 requires the plate to be unobstructed and readable.
- Rear lighting visibility — brake lights, taillights, and turn signals must remain visible to following traffic.
- Backup camera function — for vehicles with factory backup cameras, which has been a federal requirement on new vehicles since May 2018.
A standard rear-mounted spare tire cover does not interact with any of these in a normal installation. The cover sits within the footprint of the spare itself; it does not extend down into the plate or out into the lighting zones. The one exception is the backup camera, which is why we include a free centered backup-camera hole on every cover — it keeps the camera fully functional and removes the most common compliance concern.
State-level variations
State rules are mostly minor and rarely catch a properly fitted cover:
- California requires backup cameras to remain functional. A centered backup-camera hole on the cover keeps that compliant.
- New York and New Jersey inspectors occasionally flag accessories that block third brake lights. On a Wrangler, the third brake light sits on the spare-tire carrier itself, and a standard-fit cover does not block it.
- Texas and Florida have no specific spare-tire-cover language. As long as the plate is visible, the cover is fine.
- Most other states have no specific spare-tire-cover rule on the books at all.
State inspection standards check vehicle systems — lighting, brakes, emissions, and so on — not accessories that do not interfere with those systems. A properly sized cover does not come up.
The situations where a cover actually becomes a problem
Three things tend to land owners in trouble, and none of them have to do with the cover existing — they have to do with fit and condition:
- Oversized covers that extend below the spare and obscure the plate or rear lights.
- Aftermarket spare-tire carriers that physically move the spare to a position that already blocks lights or the plate. The carrier is the issue, not the cover — but a cover can make it more visually obvious.
- Damaged covers with torn flaps or loose material that drape over lights or plates.
None of these are a concern with a correctly sized cover that is kept in good condition. The standard sizes in our catalog match factory tire dimensions for each vehicle and stay well within the spare’s footprint.
International rules in brief
If you are reading this from outside the US, the same general principle applies in most countries: spare tire covers are not regulated as accessories, but plate visibility and rear lighting are. UK MOT inspectors, German TUV inspectors, and Australian roadworthy inspectors check the same things US inspectors check — whether anything obscures safety equipment. A factory-sized cover is almost always fine.
Frequently asked questions
Will I get a ticket for having a spare tire cover?
Almost never. Standard rear-mounted spare tire covers do not violate federal or state laws. The most common real-world issue is a cover blocking a backup camera — the free centered backup-camera hole on every Wheel Shell cover takes that off the table.
Does the cover affect my vehicle inspection?
No. State inspections look at vehicle systems — lights, brakes, emissions, and similar. A properly sized cover does not interfere with any of these, so it does not come up.
My state requires functional backup cameras. Will the cover still work?
Yes — choose the “with camera hole” option at checkout. The hole is centered and sized to fit any factory backup-camera position. The camera works exactly as it did before the cover went on.
What if I install an aftermarket carrier that pushes the spare lower?
Compliance comes down to whether anything ends up blocking the plate or the rear lights. The cover is rarely the issue — the carrier position is. If the spare itself blocks the plate after installation, you will need to relocate the plate (which most aftermarket carriers offer mounts for).
