SEACHOICE Lockable Spare Tire Carrier for Boat Trailer — Zinc-Plated U-Bolt, Fits 8"–15" Wheels, Padlock-Ready

SEACHOICE Lockable Spare Tire Carrier is a zinc-plated U-bolt mount that secures a spare trailer tire to a tongue or frame up to 3" wide.

This lockable U-bolt carrier gives boaters a simple, corrosion-resistant way to store a spare trailer wheel while on the road or at the ramp. Constructed with zinc plating for improved rust resistance, the carrier accepts 4- or 5-hole rims and fits wheels from 8" to 14", plus most 15" wheels. The compact design installs on either the trailer tongue or frame rails up to 3 inches wide and uses a padlock (not included) to deter theft.

How does the SEACHOICE carrier attach to my trailer?

Installation is straightforward: the U-bolt wraps around the tongue or frame and clamps through the carrier plate. No welding is required, and the hardware secures the tire snugly to the trailer.

• Zinc-plated U-bolt and mounting plate for corrosion resistance
• Fits trailer tongues or frame rails up to 3 inches wide
• Uses through-bolt hardware for a solid clamp-down
• Padlock-compatible for theft deterrence (lock not included)

What wheel sizes and rim types will this carrier hold?

The carrier is sized to accept a broad range of common trailer wheels. It supports all 8"–14" wheels and most 15" wheels, and works with both 4- and 5-hole rim patterns, making it a flexible choice for many trailer setups.

• Compatible with 4- and 5-hole rims
• Fits all 8" to 14" wheels
• Accommodates most 15" wheels—verify clearance for large offset rims
• Ideal for standard trailer tire sizes used on boat trailers

Will this carrier resist road and marine corrosion?

The U-bolt carrier features a zinc-plated finish designed to withstand moisture and road salt better than bare steel. While zinc plating improves corrosion resistance, periodic inspection and maintenance will extend service life in marine environments.

• Zinc plating helps protect against rust and surface corrosion
• Recommended for freshwater and occasional saltwater exposure with regular checks
• Simple design allows easy replacement or touch-up if plating is worn
• Store and dry if exposed to prolonged saltwater spray to prolong lifespan

Who is this for? Boaters and anglers who need an affordable, low-profile spare tire mount for their trailer will find this SEACHOICE carrier useful. It’s especially well suited for owners of small to mid-size boat trailers that use 8"–15" wheels and have tongues or frames up to 3" wide. If you want a no-frills, lockable solution that installs without welding and works with common rim patterns, this carrier is a practical choice.
