GADFISH Spare Tire Carrier
The GADFISH Spare Tire Carrier uses a heavy-duty steel frame with a reinforced triangular structure and a behind plate to secure the tire. It supports up to 150 Lbs and fits 4-, 5-, and 6-lug wheel patterns commonly found on boat trailers. Best for trailer owners who want a straightforward, rugged mount that resists loosening on rough roads. Limitations include a welded steel design that may show wear over long periods in saltwater environments; ensure proper corrosion protection during saltwater use.
GADFISH Stainless Steel Spare Tire Carrier
The stainless version offers corrosion resistance with a reinforced stainless steel build and triangular welded structure. It supports up to 120 Lbs and accommodates 4-, 5-, and 6-lug patterns, including boat trailers. Choose this if you frequently trailer in wet or salty conditions and want reduced rust risk. Caution: stainless builds can be pricier and heavier than basic steel options.
FIERYRED Trailer Spare Tire Mount
The FIERYRED unit is forged iron with powder coating, designed for up to 120 Lbs and compatible with 4- and 5-lug wheels. It includes mounting hardware for straightforward bolt-on installation without drilling. Best for users seeking a balance of strength and corrosion resistance at a reasonable price. Limitation: compatibility notes emphasize certain bolt patterns; verify your specific lug pattern before purchase.
toolhoper Trailer Spare Tire Mount
The toolhoper carrier features an upgraded 3-nut design for better locking, a high-strength steel frame with powder coating, and a 150 Lb capacity. It emphasizes low vibration and three-layer protection through bending and laser-welding. Best for long hauls where tire security and reduced loosening are priorities. A potential limitation is that installation can require precise alignment; ensure proper torque during mounting.
3001.0064 Heavy-Duty High-Mount Spare Tire Carrier
This high-mount, bolt-on carrier fits 4-, 5-, and 6-hole patterns and tires up to 16 inches. It uses a nickel-plated finish for corrosion resistance and offers a high-mount offset design to accommodate limited tongue space. Best for trailers with tight tongue areas. Limitation: some hardware packages may be sold separately for 5″ frames, so verify included hardware before buying.
MaxxHaul 50214 Spare Tire Carrier
The MaxxHaul carrier holds 4-lug and 5-lug wheels with a design that fits boat trailers well. It mounts on tongues up to 3 inches wide and 5 inches high, with an angled raised mount to improve clearance. Best for budget-conscious buyers who still require reliable mounting. Limitation: not compatible with 5 on 4-3/4″ or 5 on 5″ bolt patterns, so check your tire pattern first.
Buying Guide
- What bolt pattern does your trailer use? Most carriers list 4-, 5-, and 6-lug compatibility. Confirm your wheel pattern (4×4, 5×4.5, 6×5.5, etc.) before buying.
- Load capacity needs: Typical spare tires range from 120–150 Lbs. Choose a model with a margin above your tire weight for safety over long trips.
- Corrosion resistance: Boat trailers face exposure to water and salt. Stainless steel and nickel-plated finishes offer better rust resistance than plain steel.
- Mounting style: Bolt-on installations are common and avoid drilling, but some setups may require hardware packages sold separately. Consider tongue space and clearance when selecting high-mount versus low-mount designs.
- Installation effort: Some units use three-nut designs or multi-layer bending to reduce vibration. Factor in ease of installation and future removal for seasonal use.
- Compactness and fit: For trailers with tight tongue space, high-mount or angled designs can improve clearance and reduce wind resistance. Ensure the unit does not clash with fenders or taillights.
Frequently Asked Questions
- Do these spare tire carriers fit all boat trailers? Most listed models cover common 4-, 5-, and 6-lug patterns, but always verify bolt pattern and frame dimensions.
- Is stainless steel worth the extra cost? For trailers in corrosive environments, stainless steel offers superior rust resistance and longevity, justifying the higher price over basic steel.
- Can I install these without drilling? Many models use bolt-on installation with existing trailer hardware; some require additional hardware for specific frame sizes.
- What is a high-mount spare tire carrier? It positions the tire higher on the trailer, helping clearance on crowded tongue areas and reducing wind drag in some cases.
- What should I do to maintain these carriers? Regularly check bolts, apply anti-seize or lubricant where bolts contact the frame, and rinse after salt exposure to minimize corrosion.
- How do I choose between 120 Lb and 150 Lb options? If your spare tire approaches the heavier end (common with larger ATV or marine tires), select the higher capacity model to ensure safe mounting.
