AUTODUNK Spare Tire Mount Bracket for Trailer — 120 lb Capacity, Fits 4 & 5‑Lug (3.94–4.72" Bolt Patterns)

AUTODUNK's spare tire mount bracket secures a trailer spare on the tongue with an easy bolt-on fit for most 4- and 5-lug wheels and supports up to 120 lbs.

This compact, galvanized carrier is engineered to attach to trailer tongues up to 2.95" wide and 3.94" high without drilling, offering a low-drag profile that raises the spare for extra ground clearance. It ships with zinc-plated hardware and clear instructions so you can fasten a spare wheel with common bolt patterns (3.94", 4", 4.25" and 4.72") quickly and reliably.

How does this bracket fit different wheel bolt patterns?

The AUTODUNK mount accepts both 4-lug and 5-lug wheels across four common bolt circle diameters, giving broad compatibility for trailers and light vehicles. Its designing accommodates the lug spacing so the spare sits securely centered and stable during transport.

• Compatible bolt patterns: 3.94", 4.00", 4.25", 4.72"
• Supports 4-lug and 5-lug wheel configurations
• Includes zinc-plated mounting hardware sized for these patterns

Will it mount to my trailer tongue without drilling?

Yes — the carrier is a bolt-on design created for straightforward installation on tongues up to 2.95" wide and 3.94" tall. You do not need to drill new holes, and the kit contains the fasteners required, so installation can be completed with basic hand tools.

• No-drill bolt-on installation saves time and preserves trailer framing
• Mounting hardware included (zinc plated)
• Detailed instructions provided to guide assembly

How much weight can it safely hold and how durable is the finish?

The bracket is rated for a maximum static load of 120 lbs, suitable for most passenger and light-trailer spare tires. Its galvanized construction resists rust and corrosion, extending service life in wet and salty conditions.

• 120 lb maximum load capacity for common spare tires
• Galvanized steel resists corrosion and abrasion
• Raised design lifts wheel for improved clearance under rough terrain

Does the bracket affect trailer aerodynamics or ground clearance?

The close-to-trailer mounting reduces wind drag compared with rear-mounted carriers, while the raised architecture shifts the wheel upward to improve clearance over bumps and ruts. That combination keeps the spare out of the airflow and away from low obstacles.

• Low-profile positioning minimizes wind resistance on highway trips
• Raised wheel placement increases ground clearance
• Compact footprint preserves tongue space for other accessories

Who is this for: The AUTODUNK spare tire mount is best for trailer owners who need a reliable, no-drill spare holder that fits common 4- and 5-lug wheels and performs in wet or salty conditions. It works well for utility trailers, boat trailers, campers, and anyone wanting an out-of-the-way spare that’s easy to install using the included hardware and instructions.
