Best Spare Tire Lock for Trailers, SUVs and Jeeps

#1 · Best Overall

1. Trimax ST30

• dimensions: 2.3 x 8.8 x 11.5 in
• Material: Alloy Steel, Chrome, Stainless Steel

Best for: Frame-loop cable security.

Why it ranks #1: Its 36-inch, 12 mm cable loops around the frame and is designed to secure both the spare tire and bracket across several vehicle types.

A 36-inch, 12 mm cable that loops around the vehicle frame gives the Trimax ST30 a different approach to spare-tire security: it can connect the lock to the frame while securing both tire and bracket. That setup suits owners of trailers, motorhomes, trucks, Jeeps, or vans seeking more than a tire-only lock.

The welded cable is specified to loop around a trailer or vehicle frame, giving owners a way to secure the tire and its mounting bracket together. Its 36-inch length and 12 mm diameter define the cable format, which differs from a compact lug-replacement lock. A weather-proof cap protects the lock mechanism from harsh weather, an especially relevant detail for exposed trailer use. Buyers should account for the cable workflow when routing it around the frame and spare assembly.

Skip it if you want a lock that replaces a lug nut; the CURT 23562 is a side-mount spare-tire lock.

Choose the ST30 if your trailer, motorhome, truck, Jeep, or van has a frame route for its 36-inch cable and you want to protect both tire and bracket. Its cable-based installation is the boundary for buyers seeking a lug-style lock.

#2 · Best Side-Mount

2. Trimax TNL740

• dimensions: 5.08 x 8.38 x 13.72 in
• Weight: 3.52 oz
• Material: Alloy Steel

Best for: Universal side-mount tire owners.

Why it ranks #2: Designed for all side-mount spare tires, this alloy-steel nut lock offers a direct fit-focused option and is also listed for propane tanks.

Universal compatibility with side-mounted spare tires is the defining advantage of the Trimax TNL740, letting owners secure that mounting style without relying on a vehicle-specific lock. Its simple installation also makes it a practical option for buyers who want a straightforward theft deterrent, with an additional use for propane tanks.

The alloy-steel lock is specified for all side-mount spare tires, so its central fit is the mounting arrangement rather than a named vehicle model. The listed quick installation can make setup manageable for owners who want a basic, direct locking step. Its stated use on propane tanks adds flexibility when the same type of security is useful elsewhere. Buyers should keep the scope in mind: the supplied fit claim is for side-mounted spares, not every spare-tire configuration.

Skip it if you have a vertical-mount spare; the Heininger 6027 is specified for vertical marine, utility, and RV tires.

A good match for owners of side-mounted SUV or trailer spares who want a simple lock that can also secure a propane tank. Its stated tire fit is limited to side mounts, so other mounting arrangements need another solution.

#3

3. CURT 23562

• dimensions: 1 x 5 x 4 in
• Weight: 6.4 oz
• Material: Alloy Steel, Chrome

Best for: Chrome side-mount lock buyers.

Why it ranks #3: This steel lock is specifically designed for side-mount spare tires and has a chrome-plated finish described as corrosion-resistant.

A chrome-plated steel body gives the CURT 23562 a corrosion-resistant finish while targeting side-mount spare tires specifically. The format offers a direct choice for owners who want a compact lock for an unattended vehicle, and the two included keys provide a spare for everyday access without relying on a single key.

CURT specifies this lock for side-mount spares, so buyers can focus on that mounting style rather than a cable route around the frame. Its steel construction provides strength, while the chrome-plated finish is described as corrosion-resistant for exposure to the elements. Two included keys give owners a backup for unlocking the spare. The compact listed dimensions of 1 by 5 by 4 inches also make it a small hardware item to store with towing or vehicle supplies.

Skip it if you need a frame-loop cable that secures the bracket too; the Trimax ST30 is specified to protect both tire and bracket.

The CURT 23562 suits owners of side-mounted spares who value a steel lock, chrome-plated finish, and a second key. Its side-mount application is the key fit boundary; it is not presented as a cable lock for other layouts.

#4 · Password Lock

4. HonesaLoc Nut Lock

• dimensions: 1.69 x 1.18 x 2.25 in
• Material: Metal

Best for: Password-lock side-mount owners.

Why it ranks #4: This side-mount steel lock combines universal side-mount compatibility with a password design and a listed two-year manufacturer warranty.

A password-style lock distinguishes the HonesaLoc from key-based spare-tire options, letting owners secure side-mounted tire nuts without managing a separate key for this lock. Its steel construction and chrome-plated surface add strength and corrosion resistance, while the stated universal side-mount compatibility targets SUVs, trailers, RVs, and trucks.

The password design secures tire nuts to prevent wheel removal when a vehicle is unattended, so the locking action focuses on the fasteners. HonesaLoc specifies universal compatibility for side-mounted spares, making mounting style the central fit consideration across the named vehicle types. Steel construction supports strength, and the chrome-plated surface is described as corrosion-resistant for outdoor use. At 1.69 by 1.18 by 2.25 inches, the listed dimensions describe a compact nut-lock format rather than a long cable.

Skip it if you have a vertical marine or RV carrier; the Heininger 6027 is specified for vertical-mount spares.

This HonesaLoc is suited to owners of side-mounted SUV, trailer, RV, or truck spares who prefer a password lock on the tire nuts. Its listed compatibility is for side mounts, so vertical carriers fall outside the stated fit.

#5

5. RITE-HITE Lock Device

• Weight: 0.27 g
• Material: die

Best for: Simple lug-cover installation.

Why it ranks #5: Its listed uses include boat trailers, RVs, SUVs and cattle trailers, and the description says it installs by replacing a lug nut.

Replacing one lug nut and fitting the lock cover is the RITE-HITE device’s defining installation step, giving owners of non-operating spares a direct way to obstruct removal. The supplied description names boat trailers, RVs, SUVs, and cattle trailers, while also emphasizing that the lock is easy to install and remove.

The installation instructions describe removing one lug nut, then placing the lock and cover in position to deny access to the spare. That simple lug-based workflow can suit owners who want to secure a non-operating tire without routing a cable around a frame. The listed weather-resistant feature is relevant for exposed trailer or RV use. A lock and key are included, and the stated applications span boat trailers, RVs, SUVs, and cattle trailers; no specific thread size is supplied.

Skip it if you require a stated thread size for a Jeep; TOPSHINE lists 1/2-inch-20 thread for the 2007–2018 Wrangler JK.

Consider the RITE-HITE for a non-operating spare on a trailer, RV, SUV, or cattle trailer when a lug-based lock-and-cover installation suits the setup. The supplied details do not specify thread size, so fit information is limited.

#6 · Best Vertical-Mount

6. Heininger 6027

• Weight: 9.6 oz

Best for: Vertical marine and RV carriers.

Why it ranks #6: Made for marine, utility and RV vertical mounts, its pin fits rim thicknesses from 1/4 to 7/8 inch; it is not for trucks or SUVs.

An adjustable pin that fits rim thicknesses from 1/4 to 7/8 inch makes the Heininger 6027 a specialized choice for vertical-mounted marine, utility, and RV spares. Its flush locking design replaces one lug bolt, offering a close-fitting alternative to cable security for the carrier types it specifically names.

The 1/2-inch pin adjusts across rim thicknesses from 1/4 to 7/8 inch, helping buyers assess whether the wheel rim falls within the stated range. Its solid machined-steel, chrome-plated construction replaces one lug bolt to secure the tire to its carrier. The flush locking design keeps the lock close to the wheel, while the patented pick-proof screw and lock are specified security features. Heininger explicitly excludes truck and SUV spare tires and warns that welded spare lugs will not work.

Skip it if you need a lock for a Jeep Wrangler JL; the BOLT 7032301 is compatible with 2018+ JL models.

The 6027 fits buyers securing vertical marine, utility, or RV spares whose rims fall within its 1/4-to-7/8-inch range. It is explicitly not for truck or SUV spares, and welded lugs prevent its use.

#7 · Best Jeep Keyed

7. BOLT 7032301

• dimensions: 2.75 x 5.75 x 5.13 in
• Weight: 16 oz
• Material: Stainless Steel

Best for: Jeep Wrangler JL key users.

Why it ranks #7: This lock is compatible with 2018+ JL and opens with a compatible Jeep Wrangler ignition key, avoiding a separate lock key.

Using the compatible Jeep Wrangler ignition key to operate the lock is the BOLT 7032301’s clearest convenience: JL owners need not carry a separate spare-tire-lock key. It replaces one lug nut with a stainless-steel pin and is listed for most OEM and aftermarket alloy wheels on 2018-and-newer JL models.

The stainless-steel threaded pin replaces one lug nut, while the stated compatibility with most OEM and aftermarket alloy wheels gives JL owners a defined wheel scope. The lock learns the first key used and opens with the compatible Wrangler ignition key, reducing separate-key handling; importantly, it cannot be reset. An auto-return spring locks when the key is removed, and a stainless shutter helps keep out dirt and moisture. The supplied description recommends alloy wheels with 1-to-1 1/8-inch lug nuts for best results.

Skip it if you own a 2007–2018 Wrangler JK; TOPSHINE specifies its 1/2-inch-20 lock for that generation.

A strong fit for 2018-and-newer Wrangler JL owners who want ignition-key access and an automatically locking mechanism. Check the stated wheel and lug-nut guidance, and remember the lock permanently learns its first key.

#8

8. Prosentuo Tacoma Lock

• dimensions: 6.3 x 2.36 x 2.36 in
• Material: Aluminum

Best for: Toyota Tacoma and Tundra owners.

Why it ranks #8: Its stated fitment covers Toyota Tacoma models and Tundra models in specified ranges, with replacement part numbers listed for checking.

Vehicle-specific coverage for 2005–2026 Toyota Tacoma and 2010–2022 Tundra models makes the Prosentuo STW140 a targeted spare-tire lock choice. Its keyed system creates a physical barrier against tampering in public areas or during off-road trips, while the listed aluminum construction keeps the product’s material profile clear.

The stated Tacoma and Tundra year ranges give buyers a focused starting point for compatibility, and the lock is listed as replacing specified Toyota part numbers. Its unique keyed system is described as deterring tampering, a practical feature for public parking and off-road use. Aluminum construction is identified as rust-resistant and durable in the product details, while a scratch-resistant feature addresses surface wear. The 6.3-by-2.36-by-2.36-inch dimensions describe its form; the supplied facts do not detail installation steps.

Skip it if you own a Jeep Wrangler JL; TOPSHINE lists an M14×1.5 threaded lock specifically for 2018-and-newer JL models.

The STW140 suits Tacoma and Tundra owners within its stated model-year ranges who want keyed spare-tire security for public or off-road use. Its Toyota-specific coverage and unspecified installation steps are relevant fit and workflow boundaries.

#9

9. TOPSHINE JL Lock

• Weight: 7.04 oz

Best for: Wrangler JL M14×1.5 fit.

Why it ranks #9: Made for 2018+ Jeep Wrangler JL, it uses an M14×1.5 threaded bolt and includes two keys; confirm the thread and vehicle fitment.

The M14×1.5 threaded bolt is the defining fit detail of this TOPSHINE spare-tire lock, which is specified for 2018-and-newer Jeep Wrangler JL models. It replaces the spare-tire nut and combines an alloy lock head with a powder-coated iron rod, providing a vehicle-specific alternative to cable-style security.

TOPSHINE specifies the M14×1.5 bolt for the 2018+ Wrangler JL, giving buyers a clear model range and thread specification for a direct nut-replacement approach. The lock is described as resisting picking and impact attacks. An alloy lock head and powder-coated iron rod are listed with corrosion prevention in the product details, a useful consideration for an exposed spare. Two included keys support access if one is misplaced. Unlike a cable lock, this threaded design depends on the specified vehicle and thread fit.

Skip it if you drive a 2007–2018 Wrangler JK; TOPSHINE specifies its 1/2-inch-20 lock for that generation.

A suitable option for JL owners seeking a threaded replacement lock with two keys and corrosion-conscious materials. The M14×1.5 specification and 2018+ Wrangler JL application are its central fit boundaries, rather than broad vehicle compatibility.

#10

10. TOPSHINE JK Lock

• Weight: 7.04 oz
• Material: Iron, Metal

Best for: Wrangler JK threaded-lock buyers.

Why it ranks #10: This option targets 2007–2018 Jeep Wrangler JK with a 1/2-inch-20 threaded bolt and includes two keys, but aftermarket tire fit may vary.

A 1/2-inch-20 threaded bolt lets the TOPSHINE lock replace the factory spare-tire nut on 2007–2018 Jeep Wrangler JK models. Its vehicle-specific approach avoids a frame-routed cable, while the alloy lock head, black electrophoretic coating, and two included keys shape its use and upkeep profile.

The stated 1/2-inch-20 bolt replaces the factory tire nut on the named Wrangler JK years, giving buyers a specific threaded fit rather than broad universal compatibility. TOPSHINE describes the lock as resistant to picking and impact attacks, and lists an alloy lock head with a black electrophoretic coating. The included two keys provide access without relying on one key alone. The supplied product details caution that aftermarket tires may not fit, making tire configuration an important boundary before choosing this lock.

Skip it if you have a 2018-or-newer Wrangler JL; TOPSHINE lists a separate M14×1.5 lock for that model range.

This TOPSHINE lock suits Wrangler JK owners from 2007 through 2018 who want a threaded replacement for the factory spare-tire nut. Aftermarket tires are a stated fit concern, so its vehicle-year range alone does not settle fit.
