Joroamp Spare Tire Mount for Utility Trailer — 3-Nut Zinc-Plated Bracket, 180 lb Capacity

Joroamp's Spare Tire Mount is a bolt-on trailer bracket that secures a spare wheel using a patented 3-nut locking design and supports up to 180 lbs.

Keep a ready spare on your utility, boat, or enclosed trailer without welding or drilling: this zinc-plated steel mount gives a compact, corrosion-resistant place to carry a spare wheel, and it ships with the hardware you need for installation. The 3-nut arrangement reduces movement and noise on the road while fitting a wide range of lug patterns and bolt circle diameters.

How does the 3-nut design improve spare security?

The patented three-nut configuration clamps the wheel more evenly than a single-center stud, resisting loosening from road vibration. That means the tire stays stably positioned and produces less rattle during towing.

• Tri-point clamping reduces lateral play and wobble.
• Design minimizes vibration-related loosening over uneven routes.
• Works without extra locking accessories; nuts included.

Which wheel bolt patterns and sizes will this mount accept?

This mount is engineered for broad compatibility so you won’t need a special adapter for most common trailer wheels. It accommodates several lug counts and multiple bolt circle diameters used on utility and boat trailers.

• Fits 4-lug wheels with 4", 4.25", or 4.5" bolt circles.
• Supports 5-lug wheels with 4.5", 4.75", or 5" bolt circles.
• Accepts 6-lug wheels with 4.5", 5.32", or 5.5" bolt circles.

What materials and load rating should I expect?

The bracket is formed from welded steel that receives a zinc (galvanized-style) finish for corrosion resistance. It’s built to carry a spare up to 180 pounds, suitable for most passenger-style trailer tires and small trailer wheels.

• Welded steel construction for structural strength.
• Zinc-plated surface helps resist rust and saltwater exposure.
• Rated maximum load: 180 lb (do not exceed this limit).

Is installation difficult and what hardware is provided?

Installation is intended to be straightforward: the mount bolts on with the supplied zinc-plated fasteners, so no cutting, drilling, or welding is required in most cases. Joroamp includes clear instructions and the necessary mounting bolts and nuts so you can fit the bracket with basic tools.

• Bolt-on installation; standard wrenches or sockets required.
• All mounting hardware included in the package.
• Step-by-step instructions provided for common trailer frames.

Who is this for: This spare tire mount is aimed at trailer owners who want a secure, low-profile solution to carry a spare without permanent modification. It's a practical choice for owners of utility trailers, boat trailers, enclosed cargo trailers, and anyone who needs corrosion-resistant hardware with wide wheel compatibility and a compact installation footprint.
