Buying Guide
What lug pattern does your trailer use?
Match the carrier to 4-, 5-, or 6-lug configurations. Some models support all three with a single mount; others are limited to 4 and 5 lug patterns. Accurate matching prevents tire misalignment and failure.
How much weight will you carry?
Consider the maximum tire weight plus the carrier itself. Heavy-duty options handle up to 150 pounds, while stainless steel variants often top at 120 pounds. Do not exceed the stated limit to avoid mounting failure.
Environment and corrosion concerns
Stainless steel carriers resist rust in marine or humid environments, while powder-coated iron mounts offer good protection in general-use conditions. In salty or wet climates, rust-resistant materials extend the life of the carrier.
Installation considerations
Some carriers require drilling or specific frame dimensions. Bolt-on designs without drilling are easier but check the tongue width and available space. Three-nut designs can reduce vibration but must be properly torqued for safety.
Tongue accessibility and clearance
Ensure there is enough clearance for the spare when mounted, especially if the trailer has a swing-away design or nearby components like couplers and wiring. A raised or sloped design reduces wind resistance and ground clearance concerns on some models.
