4. Boat Trailer Spare Tire Mount — Best for Emergency Preparedness
Why We Like It
A spare tire doesn’t do much good if you don’t have a secure place to carry it. A heavy-duty boat trailer spare tire mount keeps your spare accessible while freeing up space in your tow vehicle or boat. Galvanized steel models are especially useful for boat trailers because they provide better corrosion resistance around water.
Key Features
- Heavy-duty steel construction
- Galvanized finish for corrosion resistance
- Mounts directly to the boat trailer frame
- Keeps the spare tire securely mounted and accessible
- Includes mounting hardware on many models
- Angled design can provide additional clearance
Potential Drawbacks
- Tire and wheel are usually sold separately
- Fit depends on trailer-frame size and wheel bolt pattern
- Mounting hardware may vary between models
Best For
Boat owners who want a secure, convenient place to carry a spare trailer tire for roadside emergencies.
Other Boat Trailer Accessories Worth Considering
Other useful trailer accessories include heavy-duty ratchet straps, transom tie-downs, bow stops, trailer jacks, wheel chocks, bearing protectors, tongue jacks, and trailer covers. The right combination depends on your boat, trailer design, towing distance, and how often you launch.
How to Choose Boat Trailer Accessories
Match Accessories to Your Trailer
Check your trailer’s weight capacity, frame dimensions, wheel and tire specifications, winch capacity, and mounting points before buying accessories. Accessories should be compatible with your specific trailer rather than chosen solely by price or appearance.
Choose the Right Winch Capacity
Your trailer winch should be appropriately rated for your boat and loading setup. Consider the boat’s weight, trailer angle, ramp conditions, and the amount of effort required to pull the boat onto the trailer. Never exceed the manufacturer’s rated capacity.
Check Tire, Wheel & Bearing Specifications
Before buying tires, wheels, or bearing-related accessories, verify the trailer’s tire size, load range, wheel bolt pattern, hub dimensions, and bearing specifications. Matching these details helps ensure the replacement or accessory is appropriate for your trailer.
Consider How You Launch
If you frequently launch at steep ramps, shallow ramps, rivers, or busy boat launches, prioritize accessories that make positioning and loading easier. Guide posts, a reliable winch, quality tie-downs, and properly maintained trailer components can make the process more predictable.
Boat Trailer Maintenance Tips
Inspect Tires Before Every Trip
Check tire pressure, tread condition, sidewalls, and signs of cracking or uneven wear before towing. Also inspect the spare tire and make sure it is properly inflated and ready for use.
Check Wheel Bearings Regularly
Inspect your trailer wheel bearings for proper lubrication, unusual heat, noise, or play. Follow the trailer or bearing manufacturer’s recommended inspection and service intervals, and address worn or damaged bearings before a long trip.
Rinse the Trailer After Saltwater Use
After launching in saltwater, rinse the trailer thoroughly with fresh water, paying particular attention to the frame, brakes, wheels, hubs, and other areas exposed to salt. Regular rinsing can help reduce corrosion and buildup.
Inspect Lights, Wiring & Connections
Test your trailer lights before every trip and inspect the wiring, connectors, and ground connections for corrosion, damage, or loose connections. Replace damaged components before towing.
Frequently Asked Questions About Boat Trailer Accessories
What Boat Trailer Accessories Do I Need?
At a minimum, most boat owners should consider a properly rated winch, trailer guide system, safety chains, tie-down straps, working trailer lights, a spare tire, and a suitable trailer jack. The right accessories depend on your boat, trailer, and towing conditions.
Are Boat Trailer Guide Posts Worth It?
Guide posts can be worthwhile if you regularly launch in wind, current, or busy ramps. They provide a visual reference that can help you keep the boat aligned with the trailer during loading, but they need to be properly sized and positioned for your specific trailer.
Should I Carry a Spare Tire for My Boat Trailer?
Yes. Carrying a properly matched spare tire can help prevent a flat or damaged tire from ending your trip. Make sure the spare matches your trailer’s tire size, load range, bolt pattern, and wheel specifications, and check its air pressure regularly.
