The reinforced triangular structure and behind plate stabilize the tire for long journeys. The design suits boat trailers and utility trailers that require a robust, corrosion-resistant mount. Limitations include reliance on compatible hole patterns; please verify lug count and spacing before purchase.
toolhoper Trailer Spare Tire Mount
Best for vibration reduction and secure locking. It uses an upgraded 3-nut system to lock the tire and reduce loosening while driving. The mount is powder-coated steel for rust resistance and a maximum 150 lbs load capacity. A caution: ensure your trailer frame can accommodate the three-nut design and confirm bolt hole spacing with your wheel pattern.
VONLX U-Bolt Spare Tire Carrier
Best for side-mount configurations on ski, fishing, or sailboat trailers. This carrier uses an 8.8-grade thick steel U-bolt design with galvanization to resist weather and corrosion. It fits 4 or 5 lug wheels up to 15″ tires and is straightforward to install by threading bolts into the trailer throat. Best choice for side-mounted setups; caution if your frame width differs from standard sides.
SELEWARE Spare Tire Carrier
Best for stable compatibility with larger 15″ and 16″ tires on various trailers. It features a triangular support and laser-welded backplate to handle up to 160 lbs. The universal fit targets boat, RV, and utility trailers, with tongue mounting under 6″ high and 4″ wide. A note: verify tip height and width of your tongue to ensure full compatibility.

It combines a welded, reinforced structure with a sturdy back plate and an anti-loosening setup. Choose this if you want broad trailer compatibility and robust construction; limitation includes confirming tongue dimensions for your specific trailer model.
Buying Guide
Key considerations when choosing a bolt-on spare tire carrier include compatibility, capacity, and installation. First, verify lug pattern compatibility (4-, 5-, and 6-lug options) and overall tire size (commonly 4″ to 5.5″ bolt patterns and 15″ to 16″ tires).
Material and construction matter for durability. Look for heavy-duty steel with anti-rust finishes such as powder coating or galvanization, and a solid backplate or triangular reinforcement for stability.
Mounting design also affects performance. Side-mount or tongue-mount configurations must match your trailer frame dimensions. Consider anti-loosening features (lock nuts, washers, or locking designs) to prevent tire detachment on rough roads.
Weight capacity is critical for safety. Most models target 150 lbs or slightly higher (160 lbs in some cases). If you regularly haul heavier tires, prioritize higher-capacity options and measure clearance to avoid interference with fenders or tailgates.
Ease of installation and maintenance matters. Choose products with clear mounting instructions and straightforward bolt patterns. Regularly inspect bolts and threads for signs of wear, corrosion, or loosening.
