GADFISH Stainless Steel Spare Tire Carrier
The GADFISH stainless steel model uses reinforced stainless steel with a triangular welded structure and a rectangular behind-plate. It is designed to hold a spare tire with 4″ to 5.5″ bolt patterns and supports up to 120 lbs. Best for boat trailers that operate in moist or salty environments where rust resistance is essential. Choose this if you need a corrosion-resistant, mid-weight carrier with solid structural integrity. A potential limitation is the 120-lb load cap, which may be lower than some heavier tire configurations.
GADFISH Spare Tire Carrier (Heavy Duty)
This model emphasizes heavier duty construction, rated up to 150 lbs, with an upgraded triangular welded framework and a solid rectangular back plate. It accommodates 4- to 6-lug patterns across common sizes, making it well-suited for larger tires or frequent trailer use. Best for users who consistently carry heavier spare tires or haul on rugged routes. A limitation to consider is its heavier build, which may require more robust mounting hardware or tools during installation.
Tie Down Spare Tire Carrier Mount
Designed specifically for aluminum (I-beam) trailers, this carrier features a hot-dip galvanized finish for rust protection and offers a straightforward four-hole mounting process. It supports 4- and 5-lug wheels. Best for aluminum-trailer owners who want reliable, corrosion-resistant hardware with simple installation. A caution: ensure your frame thickness and bolt hole spacing match the product’s mounting pattern to avoid misalignment.
FIERYRED Trailer Spare Tire Mount
FIERYRED offers a forged-iron spare tire carrier with up to 120 lbs capacity and powder-coated finish for rust resistance. It fits 4- and 5-lug wheels with bolt patterns up to 4.72 inches. Best for budget-conscious buyers seeking easy bolt-on installation without drilling. A limitation is the forged-iron construction which may be heavier and require careful handling during installation.
GADFISH Stainless Steel Spare Tire Carrier Mount
This elevated folding spare tire mount uses premium stainless steel and a 16.5-inch raised design to reduce ground clearance issues. It supports tires up to 150 lbs and matches 4-, 5-, and 6-lug bolt patterns across multiple diameters, with compatibility for boat trailers. Best for trailers requiring higher lift to protect the tire from scraping. A caveat is the larger footprint when folded, which may affect mounting space on smaller trailers.
Buying Guide: What to Consider Before You Buy
Load capacity and lug compatibility are the primary criteria. Choose a mount with a load rating that exceeds your spare tire weight and matches your wheel lug pattern. Corrosion resistance is key for aluminum trailers used in wet environments; stainless steel or galvanized finishes extend life. Consider mounting method: some require drilling, others are bolt-on for quick installation. Folding or elevated designs can help prevent tire contact with trailer surfaces and reduce drag. Always verify compatibility with your trailer tongue height, width, and available space.
Key factors to compare
- Weight rating: 120 lbs vs 150 lbs; ensure it covers your tire weight.
- Material: stainless steel or forged iron vs aluminum; corrosion resistance matters on water trailers.
- Bolt patterns: ensure 4, 5, and 6-lug compatibility match your wheels.
- Mounting method: bolt-on vs drilling; consider ease of installation and required tools.
- Installation space: elevated or folding designs can affect clearance and mounting area.
Practical tips
- Measure your tire diameter and backplate clearance before purchasing.
- Check trailer frame thickness and available bolt holes to avoid misfit.
- Inspect mounting hardware for corrosion protection; replace if rusted or worn.
- When in doubt, select a higher load-rated model for future tire upgrades.
FAQ
