FIERYRED Trailer Spare Tire Mount Carrier — 120 lb Capacity, Fits 4 & 5‑Lug Wheels (3.94–4.72" Bolt Patterns)

FIERYRED Trailer Spare Tire Mount is a heavy-duty, bolt-on carrier that secures a trailer spare up to 120 lbs and fits both 4- and 5-lug wheels with common bolt patterns.

Whether you tow a utility trailer, boat trailer, or general-purpose trailer, having a reliable spare tire mount improves readiness and frees up space on your trailer deck. This FIERYRED carrier clamps to trailer tongues up to 2.95" wide and 3.94" high and accepts 3.94", 4.00", 4.25", and 4.72" bolt patterns so it works with many common trailer wheels. Forged-iron construction, robust welds, and corrosion-resistant finishes make this bracket suited for outdoor use and marine environments.

How does this mount attach to my trailer and how simple is installation?

Installation is a bolt-on design that requires no drilling in most setups — the included mounting plate and hardware let you attach the carrier securely to your trailer tongue. The package contains zinc-plated bolts and nuts so you can complete mounting right away.

• Bolt-on fitting for fast, tool-based installation.
• Includes zinc-plated mounting hardware; no extra fasteners needed.
• No-drill setup on compatible trailer tongues up to 2.95" wide and 3.94" high.
• Clear instructions reduce install time and effort.

What wheel sizes and bolt patterns will this spare carrier accept?

This carrier is engineered to accept both 4-lug and 5-lug wheels and accommodates several common bolt circles, making it compatible with a wide range of trailer rims. Measure your wheel’s bolt pattern to confirm fit before purchasing.

• Fits 4- and 5-lug wheels.
• Compatible bolt patterns: 3.94" (100 mm), 4.00", 4.25", and 4.72" (120 mm).
• Designed for typical trailer tire diameters and rims used on boat and utility trailers.
• Raised mounting keeps wheel higher for improved ground clearance.

How durable is the FIERYRED carrier for harsh or marine environments?

Durability is prioritized: the bracket is forged from iron, welded solidly, then finished with powder coating and supplied with zinc-plated hardware to resist rust and corrosion. Rated to hold up to 120 lbs, it’s built for the rigors of road and dockside exposure.

• Forged-iron construction and heavy welds for structural strength.
• Powder coating plus zinc-plated bolts for enhanced corrosion resistance.
• 120 lb load rating supports most trailer spare tires and wheels.
• Close-to-trailer placement reduces wind drag while towing.

Will the design affect trailer clearance or towing performance?

The mount’s compact, close-to-trailer design minimizes added drag and places the spare high enough to reduce interference with ground obstacles. The raised wheel position helps maintain ground clearance without protruding far from the trailer profile.

• Low-profile mounting reduces wind resistance compared with rear or side carriers.
• Raised position improves ground clearance over bumps or ramps.
• Keeps spare secure and accessible while staying close to trailer tongue.
• Simple removal lets you take the carrier off when not needed.

Who is this for: The FIERYRED Trailer Spare Tire Mount is for trailer owners who want a secure, easy-to-install spare holder that fits many common rim patterns. It suits boaters, landscapers, campers, and anyone towing a small utility or cargo trailer who needs a durable, corrosion-resistant carrier rated for heavier spares up to 120 lbs.
