Buying Guide
What to consider when choosing a boat trailer tire carrier
Load capacity: Match the maximum wheel weight to your spare. Heavier loads require reinforced mounts, especially for rough roads on water launches.
Mounting style: Tongue-mount vs frame-mount—consider space constraints and whether you need added security or easier maintenance.
Bolt pattern compatibility: Confirm it supports your wheel’s lug count and spacing (4-, 5-, or 6-lug configurations).
Material and finish: Stainless steel or powder-coated steel resist rust in marine environments; stainless options excel where water exposure is frequent.
Security features: Lockable carriers deter theft, particularly for exposed trailers at marinas or campsites.
Installation ease: Bolt-on designs save time but ensure you have the correct tools and hardware for your trailer model.
Installing and maintaining your spare tire carrier
Follow manufacturer guidelines for mounting torque and hardware type. Periodically inspect bolts and welds for signs of loosening or corrosion, especially after rough trips or saltwater exposure.
