WELLUCK Trailer Spare Tire Mount — 3-Nut Carrier fits 4/5/6/8-Lug Wheels, 180 lb Capacity, Anti-Theft Cable

WELLUCK's 3-nut trailer spare tire mount is a heavy-duty, triangular steel bracket that secures a spare tire to utility and boat trailers, fitting multiple lug and bolt patterns while offering an anti-theft cable and 180 lb capacity.

If you tow a utility trailer, boat trailer, camper or RV, a dependable spare-tire carrier is essential. This WELLUCK mount was engineered to accept 4-, 5-, 6- and 8-lug wheels across a wide range of bolt patterns (4", 4.5", 4.75", 5", 5.5", 6" and 6.5") and to fasten quickly to rectangular trailer frames up to 6.2" long by 3.9" wide. Built from 5mm steel with a sandblasted finish and a reinforced triangular profile, it balances strength, corrosion resistance and ease of installation.

How does the 3-nut fixation system adapt to different wheel lug patterns?

The 3-nut design centers the wheel on the bracket while allowing the mount to accept several lug configurations and bolt circle diameters. Instead of relying on a single stud pattern, the three fastening points stabilize the wheel across irregular lug placements.

• Works with 4, 5, 6 and 8-lug wheels
• Compatible with 4" to 6.5" bolt patterns listed
• Three nuts distribute clamping force for a secure fit

Will this bracket withstand road use and exposure to water?

Yes — the carrier uses 5mm steel with a sandblasted surface to reduce surface rust and increase paint adhesion for longer life in marine and road environments. The triangular welded structure adds stiffness so the mount resists bending and shaking under load.

• 5mm thick steel construction for high strength
• Sandblasted finish improves corrosion resistance
• Reinforced triangular geometry reduces flexing

How secure is the spare tire against theft and vibration?

The package includes a steel security cable that threads through the tire and anchors to the bracket so you can use your own lock (not included) for theft deterrence. The 3-nut clamp plus the triangular bracket keeps the wheel centered and tight to minimize wobble while towing.

• Steel security cable for added theft protection
• 180 lb rated load capacity for most trailer spares
• Three-point clamping reduces rotational play and vibration

How simple is the installation — do I need special tools or modifications?

Installation is designed to be straightforward: the kit includes all mounting hardware and clear instructions, and only a standard wrench is required. The bracket mounts to rectangular frame rail sections up to 6.2" by 3.9" without drilling or welding on most applications.

• Fits frames up to 6.2" long x 3.9" wide
• All bolts and hardware included in the kit
• Installable with a single standard wrench — no drilling usually required

Who this is for: If you need a robust, adaptable spare-tire carrier for utility trailers, boat trailers, campers or light RV use, the WELLUCK mount is built for compatibility and longevity. Choose this bracket when you want a versatile fit for multiple lug and bolt patterns, corrosion-resistant steel construction, easy bolt-on installation and an included anti-theft cable to keep your spare secure at the dock or on the road.
