GADFISH Spare Tire Carrier — Heavy Duty 150 Lbs
Best for heavy loads and universal 4–6 lug patterns. This mount features a reinforced triangular structure with a robust behind plate to secure the tire and prevent looseness. It is designed to fit 4″ to 5.5″ bolt patterns and supports up to 150 lbs. The rugged construction suits boat trailers and utility trailers that carry larger tires. Caution: ensure mounting surface is flat and structurally sound to maximize stability.
toolhoper Trailer Spare Tire Mount — 150 Lbs
Better for vibrations and noise control with the upgraded 3-nut locking design. Powder-coated steel provides rust resistance, and the dual-plane bending panels increase stiffness for long travels. Best for utility trailers that regularly traverse uneven terrain. Limitation: while rated up to 150 lbs, heavier tires should be confirmed against your axle and frame capacity.
GADFISH Stainless Steel Spare Tire Carrier
Best for corrosion resistance in wet environments. This stainless steel mount reduces rust risk and maintains a clean look. It supports similar lug patterns as the non-stainless version and uses a triangular welded structure for stability. Choose this if your trailer operates near saltwater or humid conditions. Limitation: stainless steel may be costlier than other options.
VIAGL U-Bolt Trailer Spare Tire Bracket
Best for quick installs on frames up to 2–3 inches wide with compatibility to 4–5 lug wheels. Built from high-quality steel with galvanized coating for weather resistance. The inclined bolt design strengthens tire lock and reduces wind resistance. Caution: verify overall tire clearance on your trailer to avoid ground contact on rough roads.
PAULINN 3-Nuts Upgraded Spare Tire Mount
Best for wide wheel compatibility including up to 8-lug configurations and 6″ bolt patterns. The 3-nut design and anti-theft rope provide enhanced security and stability, with a heavy-duty 180 lbs capacity. Durable welded construction and rust-resistant finish suit varied trailer types, such as boat trailers, campers, and RVs. Limitation: ensure compatibility with your specific bolt pattern and mounting surface dimensions.
MAXXHAUL 70214 Spare Tire Carrier
Best for smaller to mid-size trailer tires, compatible with 4- and 5-lug patterns. Mounting on trailer tongues up to 3 inches wide enables flexible placement. The angled, raised mount design helps clear the ground and boats. Caution: not suitable for very large or high-profile tires beyond the listed bolt patterns.
Buying Guide
What to consider when choosing a trailer spare tire mount
- Load capacity: Match the tire weight and trailer usage. Most options handle 150–180 lbs; verify your tire’s weight and the mount’s rating.
- Lug compatibility: Confirm lug count and bolt pattern compatibility (4 to 8 lugs, patterns from 4″ to 6.5″).
- Construction material: Stainless steel and powder-coated steel resist rust; iron versions offer strength but may require care in corrosive environments.
- Mount design: Look for triangular supports and reinforced back plates for stability; some models use three-nut or multi-nut systems for security.
- Installation: Consider frames and tongue width; some mounts use U-bolts or simple bolt-in methods with no drilling required.
- Environmental exposure: If exposed to saltwater or heavy rain, stainless or galvanized steel options are preferable.
- Clearance and ground clearance: Ensure the raised/angled design provides sufficient tire clearance and avoids contact with ground or trailer components.
