Buying Guide: Key Considerations For Your Trailer Spare Tire Bracket
When choosing a spare tire bracket for trailers, consider material, load rating, mounting style, and bolt-pattern compatibility. You want a mount that secures the tire firmly while resisting corrosion and weather exposure.
- Material and finish: Stainless steel and galvanized steel resist rust; iron with powder coating offers strong support but may require maintenance in harsh environments.
- Load capacity: Match the tire’s weight to the bracket’s rating. Going under your tire’s actual weight can risk failure on rough roads.
- Bolt pattern compatibility: Confirm your wheel’s lug count (4, 5, or 6) and bolt circle diameter to ensure a proper fit.
- Mounting location: Side mount vs. back plate. Side mounts save space; back plates offer robust protection against tire shifts.
- Installation effort: Some models require drilling or frame modifications; others are drill-free or use simple bolt-on designs.
- Security features: Some brackets include anti-theft or locking mechanisms; consider if security is important for your setup.
