eCustomrim 2-Pack Trailer Tire Rim Assembly ST175/80D13 13 Inch Black Wheel
This bias-ply trailer tire assembly is rated for 1360 lbs max load at 50 PSI with a 24.4″ overall diameter and Load Range C. The 13×4.5″ rim uses a 5-lug pattern for secure lug alignment. DOT-approved as a ready-to-use assembly with a two-year warranty and roadside assistance.
Best for: Small to mid-size boat trailers that need a cost-effective, ready-to-mount tire/rim package. Choose this if you want a budget-friendly, DOT-approved assembly with roadside support.
Limitation: May be less suitable for very heavy loads or high-speed highway use on larger boats. Check compatibility with your current hubs and lug pattern.
eCustomrim 2-Pack ST175/80D13 White Wheel
This DOT-approved tire/wheel assembly uses the same bias-ply tire dimensions as the black version but arrives with a white wheel to match certain trailer aesthetics. It offers the same 1360 lbs max load at 50 PSI and a 24.4″ overall diameter with a 5-lug bolt pattern.
Best for: Boat trailers prioritizing a white-wheel appearance or matching existing white components while maintaining standard load and performance.
Caution: Ensure color preference aligns with your trailer’s steel or aluminum finish to avoid undesired weathering or contrast over time.
Free Country Grand Ride Set 4 Trailer Tires ST225/75R15
Set of four radial tires with a 10-ply construction and Load Range E. The tread includes a Scuff Guard feature and a cap ply (nylon overlay) across the tread, which can contribute to improved wear and sidewall protection on boat ramps and road surfaces.
Best for: Bigger, heavier boat trailers requiring higher load capacity and extra durability during longer highway hauls.
Caution: This set is a larger tire footprint; ensure your trailer frame, wheel wells, and axles have adequate clearance for the ST225/75R15 sizing.
eCustomrim 2-Pack Trailer Tire Rim Assembly 4.80-12 480-12
This smaller-diameter assembly uses a 4.80-12 tire with a 12″ rim, 2.95″ center bore, and a 5-lug layout. Rated for 990 lbs max load and up to 60 PSI, it suits compact utility boats and smaller trailers while offering a two-year warranty and roadside assistance.
Best for: Compact or lightweight boat trailers needing a reliable, space-saving option that still provides a DOT-approved assembly.
Limitation: Lower load capacity means it’s not suitable for heavier boats or utility trailers carrying extra gear on long trips.
WANDA Trailer Tire Wheel Assembly 20.5×8-10
Designed for boat and motorcycle trailers, this assembly offers a 10-ply rating with a load index of 95 and a speed rating of L (up to 75 mph). It uses a 5-lug on a 4.5″ bolt pattern and a white wheel.
Best for: High-speed highway towing and trailers needing stronger construction for larger boats or heavier gear. The larger wheel size helps with stability on longer trips.
Caution: Ensure compatibility with your trailer’s axle and frame clearance, as the larger diameter may affect ramp fit and fender clearance.
Buying Guide
What should you consider when choosing boat-trailer tires?
- Trailer size and load: Match tire size and load range to your boat weight and trailer axles. Higher loads may require Load Range E or larger tires.
- Wheel compatibility: Confirm lug pattern (e.g., 5 on 4.5″), center bore, and wheel width to ensure secure mounting and proper hub alignment.
- Tire type and construction: Bias-ply vs radial tires offer different ride characteristics and durability. Radials generally provide better highway stability; bias-ply tires can be cost-effective for lighter trailers.
- Sidewall protection and tread: Features like Scuff Guard and deeper tread contribute to longer life on ramps and varied road surfaces.
- DOT approval and warranties: DOT-approved assemblies provide baseline safety standards, and warranties can offer roadside assistance in case of failures.
What size should you choose for a boat trailer?
- Small boats: ST175/80D13 or 4.80-12 tires with corresponding 13″ or 12″ rims are common and budget-friendly.
- Mid-size to large boats: ST225/75R15 or larger 20.5×8-10 tires with Load Range E provide higher load capacity and stability at highway speeds.
- Two options to compare: A compact setup (4.80-12) versus a larger footprint (ST225/75R15) reduces ramp resistance and improves tracking when towing at longer distances.
How to install and maintain boat-trailer tires?
- Follow manufacturer torque specs for lug nuts and ensure proper seating of the tire on the rim.
- Inspect tires for cracks, wear, and sidewall damage before each trip. Check inflation and look for uneven wear patterns that indicate alignment issues.
- Rotate or replace tires when tread depth becomes shallow or after hitting substantial road hazards to mitigate blowouts.
What about safety features to look for?
- DOT-approved assemblies for safety assurance.
- Sidewall protection features like Scuff Guard can help resist curb and ramp scrapes.
- Two-year warranties with roadside assistance provide coverage for critical incidents on excursions.
Choosing among the five options: quick questions
- Need a budget-friendly, small-trailer solution? Consider the eCustomrim ST175/80D13 assemblies.

Frequently asked questions
- What tire size is best for a mid-size boat trailer? A size like ST225/75R15 or larger is common for mid-size trailers, depending on axle capacity and trailer frame clearance.
- Are tire/rim assemblies safer than separate tire and rim purchases? DOT-approved assemblies simplify mounting and ensure compatibility with standard trailers, which can improve reliability on the road.
- Can I mix tire brands on a dual-axle boat trailer? It’s best to match tires by size, load range, and speed rating on each axle to avoid inconsistent handling.
- How often should I inspect trailer tires? Check pressure and tread condition before every trip and at least monthly during storage, looking for cracks, bulges, or uneven wear.
- Is a higher load rating always better for a boat trailer? Higher load ratings are beneficial for heavier boats or when towing at highway speeds, but ensure the axle, rim, and frame support the increased capacity.
- What is the advantage of a radial tire for a boat trailer? Radial tires typically offer better highway stability, smoother ride, and longer wear than bias-ply tires in many trailers.
