A loose spare tire or poorly matched carrier can create noise, damage the trailer, and leave you without a usable spare when you need it. The GADFISH Spare Tire Carrier is a bolt-on mount designed to hold wheel and tire assemblies weighing up to 150 lbs without requiring you to drill into a compatible trailer frame. Its reinforced triangular structure, solid-iron construction, and broad lug-pattern support make it a practical option for many boat and utility trailers. Its main limitation is corrosion care, since sandblasted iron still needs inspection and maintenance around saltwater.
Quick Verdict
Editorial Rating: 8/10, recommended with fit and maintenance caveats
Best For: Boat, cargo, and utility trailer owners who need a strong bolt-on carrier for a supported lug pattern.
Bottom Line: The GADFISH carrier combines a useful 150 lb limit with broad wheel compatibility and drill-free installation. You must still confirm the trailer frame, wheel weight, clearance, and corrosion protection before relying on it.

What Is the GADFISH Spare Tire Carrier?
The GADFISH Spare Tire Carrier is an external bracket that lets you secure a spare wheel and tire assembly to a compatible trailer frame. It is intended mainly for boat trailers, utility trailers, cargo trailers, and similar setups that do not already have a practical spare-tire location.
The carrier uses a welded triangular structure and a rectangular support plate to brace the mounted wheel. Its raised, sloping design is intended to hold the spare away from the ground while avoiding the complexity of an under-trailer mechanism or a custom welded mount.
This product is an add-on carrier, not a complete spare-tire system. You still need a correctly sized spare wheel, suitable mounting hardware, enough frame strength, and adequate clearance around the tire.
Who Should Buy It?
Best For
- Trailer owners whose spare wheel matches one of the supported bolt patterns.
- Buyers who want a bolt-on installation rather than drilling or welding.
- Boat, cargo, or utility trailer owners with a wheel assembly below the 150 lb limit.
Skip If
- Your wheel pattern, trailer frame, or mounting location does not match the bracket.
- Your complete spare assembly weighs more than 150 lbs.
- You need a maintenance-free stainless steel carrier for frequent saltwater exposure.
Before You Buy: Confirm the complete wheel-and-tire weight, bolt pattern, available frame space, ground clearance, light visibility, license-plate visibility, and access to the trailer before ordering. A supported lug pattern alone does not guarantee that the bracket will fit every trailer.
Fit and Compatibility
The carrier covers several common trailer wheel patterns. It supports a 4-lug wheel with a 4-inch pattern, 5-lug wheels with 4.5-inch, 4.75-inch, or 5-inch patterns, and a 6-lug wheel with a 5.5-inch pattern.
You should verify more than the number of lugs. Two wheels can have the same lug count but different bolt-circle diameters. Five-lug measurements are also easy to misread, so check the wheel or trailer documentation when possible instead of relying only on a quick ruler measurement.
The wheel and tire together must remain below 150 lbs. The carrier’s stated capacity does not increase the trailer frame rating, axle capacity, payload limit, or tongue-weight allowance. The chosen mounting point must be strong enough to support the spare during bumps, braking, and vibration.
Pro Tip: Test the proposed location with the spare held in position before tightening the bracket. Turn the tow vehicle and trailer through a tight angle, open nearby gates or storage doors, and check that the tire will not block lights or strike the trailer body.
Materials and Build Quality
The reviewed carrier is described as industrial solid iron with a sandblasted finish. Iron gives the bracket the rigidity needed to support a heavy spare, while the triangular reinforcement and rectangular back plate spread the load across the mounting structure.
The braced design is more important than appearance. A flat, unsupported plate can flex as a trailer moves over rough pavement. The triangular section is intended to resist that movement and keep the wheel closer to the bracket.
Sandblasting creates a clean, even surface, but it should not be confused with stainless steel. Salt spray, road salt, standing water, and chipped surface protection can still lead to corrosion. Inspect the welds, edges, fasteners, and contact points regularly.
Installation and Setup
The GADFISH carrier uses a bolt-on design with different-length hardware. A compatible installation should require a suitable wrench or socket rather than drilling, cutting, or welding.
| Step | What to Do | Why It Matters |
|---|---|---|
| 1 | Confirm the wheel’s lug pattern and total weight. | This prevents ordering a carrier that cannot safely hold the spare. |
| 2 | Choose a clean, level, structurally sound frame location. | Uneven or damaged surfaces may keep the bracket from sitting securely. |
| 3 | Position the back plate and select the correct supplied bolts. | Correct bolt length helps the hardware clamp without poor thread engagement. |
| 4 | Tighten the frame hardware evenly. | Even tightening reduces twisting and helps the bracket sit flat. |
| 5 | Mount the spare and secure all wheel fasteners. | The wheel should sit firmly without rocking against the carrier. |
| 6 | Recheck clearance and inspect the hardware after the first short trip. | Initial vibration may reveal movement that was not obvious during setup. |
Use the product instructions and the trailer manufacturer’s guidance for fastener tightening. Do not guess at a universal torque value, since bolt size, grade, thread condition, and frame construction can differ.
Compatibility and Safety
A trailer-mounted spare is exposed to vibration, water, road debris, and repeated loading. Check that all fasteners have full thread engagement, the wheel is seated correctly, and the carrier does not move when you push and pull the mounted tire.
The installation must not cover brake lights, turn signals, reflectors, the license plate, safety chains, electrical connectors, or required trailer equipment. It should also leave enough room for the tow vehicle and trailer to turn without the spare touching the tongue, jack, body, or vehicle bumper.
Do not stand, climb, or place cargo on the carrier. Its 150 lb rating applies to the supported spare assembly, not passengers, storage platforms, or added equipment.

How It Performs in Real Use
For Boat Trailers
The no-drill mounting style is useful when you do not want to alter a compatible trailer frame. The raised position can also keep the spare more accessible than an under-frame location. Saltwater users will need to rinse the bracket and hardware with fresh water, dry them when practical, and address surface damage before rust spreads.
For Highway Towing
The reinforced triangular structure is designed to reduce movement under a loaded spare. Correct installation remains essential because highway vibration can loosen poorly seated hardware. Inspect the mount before long trips and after rough-road travel.
For Utility and Cargo Trailers
The broad lug-pattern range makes the carrier useful across many small and medium trailer setups. Placement may be more difficult on trailers with mesh sides, ramps, toolboxes, jacks, or limited tongue space. Test access to every moving part before choosing the final position.
For Long-Term Storage
An externally mounted spare remains exposed to sunlight, moisture, and dirt. A tire cover may help protect the tire, but it does not replace checks for inflation, sidewall cracking, rust, loose hardware, or water trapped around the bracket.
Maintenance and Corrosion Care
Inspect the carrier before towing and during normal trailer maintenance. Look for loose nuts, elongated mounting holes, cracked welds, bent sections, rust around hardware, and movement between the tire and bracket.
After saltwater launches or winter road use, rinse away salt and allow the assembly to dry. Touch up damaged protective surfaces with a coating suitable for exterior metal. Replace badly corroded, stretched, or damaged hardware rather than tightening it repeatedly.
Also check the spare itself. A secure carrier does not help if the tire is flat, weather-cracked, or the wrong size for the trailer.
Pros and Cons
Pros
- Supports complete spare assemblies weighing up to 150 lbs.
- Fits several common 4-, 5-, and 6-lug trailer wheel patterns.
- Bolt-on installation avoids drilling on a compatible frame.
- Triangular reinforcement and a rear plate help control flex.
- Different-length mounting bolts allow some installation adjustment.
Cons
- Supported bolt patterns do not guarantee compatibility with every trailer frame.
- Solid iron requires more corrosion care than a stainless steel mount.
- No universal tightening torque or frame-size range is confirmed in the reviewed information.
Is It Worth the Price?
The GADFISH Spare Tire Carrier is positioned as a value-oriented alternative to custom fabrication and premium stainless steel mounts. Its strongest value points are the 150 lb rating, multiple supported bolt patterns, reinforced structure, and no-drill installation.
It offers the most value when your trailer and spare already match the published requirements. A straightforward bolt-on fit can save the time and expense of welding a custom bracket.
It is not the best fit when corrosion resistance is your top priority or when your trailer requires a folding, under-frame, bumper-specific, or stake-pocket design. Paying more for a mount designed around those needs may prevent installation compromises.
How It Compares to Alternatives
A stainless steel GADFISH carrier is worth comparing if your trailer frequently enters saltwater and corrosion resistance matters more than the lowest purchase cost. A GADFISH stake-pocket carrier may be a better match for utility trailers that already have compatible stake pockets.
A folding carrier is more useful when the spare would otherwise block a rear door, ramp, or cargo area. The reviewed solid-iron carrier makes the most sense when you want a simple, fixed bracket with broad wheel-pattern support and do not need a folding mechanism.
Frequently Asked Questions
Which wheel bolt patterns does the carrier support?
It supports 4-lug wheels with a 4-inch pattern, 5-lug wheels with 4.5-inch, 4.75-inch, or 5-inch patterns, and 6-lug wheels with a 5.5-inch pattern. Confirm the bolt-circle diameter instead of checking only the number of lugs.
Does installation require drilling?
The carrier is described as a bolt-on design that does not require drilling or cutting when installed on a compatible trailer frame. You still need to confirm that the supplied hardware fits the selected mounting point.
Does it include the required mounting hardware?
The product information states that different-length bolts are supplied for installation. Check the package contents before starting and do not substitute weaker, damaged, or poorly fitting fasteners.
Can it carry any spare tire under 150 lbs?
No. The complete wheel and tire must be under 150 lbs, but the bolt pattern, available frame space, hardware fit, and surrounding clearance must also be compatible. The trailer frame must be suitable for the added load.
Is the sandblasted finish rustproof?
You should not treat sandblasted solid iron as permanently rustproof. Rinse away salt, inspect the finish, dry the bracket when practical, and repair damaged protective surfaces before corrosion spreads.
Will the raised design block rear visibility or trailer lights?
That depends on the mounting location, spare size, and trailer layout. Hold the spare in the proposed position and verify that it does not block required lights, reflectors, the license plate, a rear camera, or your view before completing installation.
What does the stated 18 months of support include?
The stated support period covers access to assistance with installation questions and product issues. It should not be assumed to provide every remedy associated with a full warranty, so check the current seller and manufacturer terms before buying.
The Bottom Line
The GADFISH Spare Tire Carrier is a solid choice for trailer owners who have a supported wheel pattern, a suitable frame location, and a complete spare assembly below 150 lbs. Its main strengths are its reinforced bolt-on structure and broad compatibility, while its main limitation is the care required to protect solid iron from corrosion.
Skip it if you need stainless steel, a folding design, a stake-pocket mount, or guaranteed fitment for a frame that has not been measured.
