Joroamp Spare Tire Mount for Utility Trailer — 3-Nut Bolt-On Carrier, 180 lb Capacity, Galvanized Steel

Joroamp's Spare Tire Mount for Utility Trailer is a reinforced, bolt-on carrier with a patented 3-nut locking design that secures spare wheels up to 180 lbs and reduces vibration on the road.

Keep a ready spare without drilling or custom fabrication: this trailer-mounted carrier fits a wide range of wheel bolt patterns, ships with zinc-plated hardware, and uses welded, galvanized steel to resist corrosion. It’s built to cut rattling and prevent loosening over time, while providing a straightforward installation that bolts to most trailer frames.

How does the 3-nut design improve spare tire security?

The three-nut arrangement clamps the spare more evenly than a single-stud style, minimizing movement that can cause noise and fastener loosening. By distributing pressure across three points, it reduces wobble and helps keep the tire reliably seated during towing.

• Three-point locking reduces lateral and rotational play.
• Patent-pending layout helps prevent nuts backing off while driving.
• Designed to lower vibration-related noise on rough roads.

Will this mount fit my trailer’s wheel bolt pattern?

The mount was engineered for broad compatibility across common bolt patterns so you can avoid guessing measurements. It fits both 4-, 5-, and 6-lug wheel layouts with multiple hole diameters, accommodating most small utility, boat, and enclosed trailers.

• 4-lug compatibility: fits 4", 4.25", and 4.5" hole diameters.
• 5-lug compatibility: fits 4.5", 4.75", and 5" hole diameters.
• 6-lug compatibility: fits 4.5", 5.32", and 5.5" hole diameters.

How strong and weather-resistant is the mount?

Constructed from welded steel with a galvanized/zinc-plated finish, the mount resists rust and handles the conditions trailers face. It’s rated to hold up to 180 pounds, covering most spare tire needs without flexing or failing under normal towing loads.

• Welded reinforced frame for added rigidity and longevity.
• Zinc plating and galvanization for corrosion resistance.
• Maximum safe load rating of 180 lbs for typical spare tires.

Is installation difficult and what hardware is included?

Installation is designed to be simple and non-invasive: the mount bolts to your trailer—no cutting or drilling required. The package includes zinc-plated mounting hardware and clear instructions so you can install the carrier quickly with basic hand tools.

• Bolt-on design attaches to existing frame or bumper mounts.
• Comes with zinc-plated bolts and nuts—no extra purchases needed.
• Step-by-step instructions for straightforward assembly and mounting.

Who is this for? If you tow a small utility, boat, or enclosed trailer and want a durable, low-noise spare tire solution that fits multiple wheel patterns, the Joroamp Spare Tire Mount is designed for you. It suits trailer owners who prefer a bolt-on, corrosion-resistant carrier that reduces vibration, secures the wheel with a three-point clamp, and arrives ready-to-install with hardware included.
