GADFISH Spare Tire Carrier
The GADFISH spare tire mount is designed to handle up to 150 lbs with a reinforced triangular structure and a sturdy behind plate. It supports 4-, 5-, and 6-lug patterns (4″ to 5.5″ bolt patterns), making it a flexible option for jet ski trailers that may switch tire sizes. Best for boat trailer owners needing robust security and a clean surface finish due to sandblasting. Choose this if you require high load capacity and broad compatibility. A potential limitation is the lack of explicit installation hardware details in the listing, so verify included components before purchase.
eCustomrim Trailer Tire Rim Assembly 4.80-12
This complete tire and rim assembly is rated for 785 lbs max load and 60 PSI, built for reliable trailer operation. It features a 12×4 inch rim with a 4-lug pattern and 5-lug compatibility, plus a DOT-approved assembly and 2-year warranty with roadside assistance. Best for users who want an all-in-one solution with DOT compliance and aftermarket roadside support. It may be better for smaller jet ski trailers with 4-lug configurations and a need for immediate tire-rim readiness; it’s less ideal if you specifically need a carrier-only mounting bracket rather than a full tire assembly.
eCustomrim 2-Pack Trailer Tire Rim Assembly ST175/80D13
This set provides two complete tires and rims designed for ST175/80D13 size, with a 5-lug 4.5″ bolt pattern. It offers a 1360 lbs max load, 50 PSI, DOT-approved assembly, and roadside assistance. Best for jet ski trailers that require a ready-to-install pair of tires and a stable, load-rated setup. It’s a solid option for expanding or replacing multiple tires, but ensure your trailer’s bolt pattern aligns with 4.5″ centers and 5-lug configuration to avoid misfit.
eCustomrim 2-Pack White Wheel 4.80-12
Similar to the previous, this 2-pack includes bias ply tires rated for 785 lbs with a 60 PSI maximum. The 4.80-12 size is common for smaller trailers. It uses a 12×4 inch rim with a 5-lug 4.5″ bolt pattern and DOT-approved assembly, plus a 2-year warranty with roadside assistance. Best for jet ski trailers needing a white-painted wheel for aesthetics or visibility. If your system requires a different color or a single tire, consider alternatives with more flexible packaging.
Qualward Spare Tire Mount Bracket
The Qualward bracket offers upgraded compatibility with 4, 5, and 6 lug patterns and mounting on trailer tongues up to 4″ wide by 5″ tall. It’s forged iron with powder-coated finish for rust resistance and a load rating up to 150 lbs. Best for trailers needing strong, rust-resistant brackets with broad lug-pattern support. A limitation is that universal installation on very small tongues may require adapters or additional hardware not listed in the product page.
Extreme Max 3004.4553 Economy Carrier
The Extreme Max model features heavy-duty welded zinc-plated steel and fits 4-hole and 5-hole rims with 4″ and 4.5″ bolt circles. It’s designed for front or mid-trailer mounting, making it versatile for jet ski trailers that place the spare toward the vehicle’s front or midsection. Best for trailers needing a simple, sturdy mounting solution. It may not offer as wide a bolt-pattern range as some universal brackets, so verify compatibility with your wheel hub.
toolhoper Trailer Spare Tire Mount
The toolhoper carrier uses an upgraded 3-nut design to lock tires more securely and reduce vibration. It’s built from powder-coated steel for rust resistance and supports up to 150 lbs. Best for heavy-duty trailer setups where vibration control and extra security are priorities. A potential limitation is the added hardware required for install, so confirm the exact mounting kit included before proceeding with installation.
AUTODUNK Spare Tire Mount Bracket
AUTODUNK offers a 120 lbs capacity bracket designed for 4- and 5-lug wheels with bolt patterns 3.94″, 4″, 4.25″, and 4.72″. It’s intended for trailer tongues up to 2.95″ wide, with galvanized material for rust resistance. Best for smaller jet ski trailers needing a compact, corrosion-resistant solution. It may be less suitable for larger tires or heavier loads due to its more modest weight rating and tongue width requirement.
Buying Guide: Key Considerations for Jet Ski Trailer Spare Tire Carriers
- Bolt pattern compatibility: Confirm the lug pattern (4×4, 5×4.5, 5×5.5, etc.) of both your wheel and trailer tongue to avoid incompatible mounting.
- Load capacity: Choose a carrier that matches or exceeds your spare tire weight, plus a safety margin for highway conditions and rough roads.
- Mounting location: Decide between front, mid-trailer, or tongue-mounted setups based on space, accessibility, and trailer design.
- Material and finish: Look for reinforced steel with rust-resistant finishes (zinc plating, powder coating) to withstand marine or saltwater environments.
- Installation ease: Some products include detailed hardware and instructions; others may require additional parts. Consider your DIY comfort level.
- Complete assemblies vs. brackets: Complete tire assemblies (tire + rim) provide ready-to-use options but may limit customization. Universal brackets offer flexibility but require separate tires.
- Warranty and roadside support: DOT approvals and warranties can provide peace of mind for long trips and remote locations.
