eCustomrim 2-Pack ST175/80D13 Trailer Tire Rim Assembly
This assembly uses a bias ply trailer tire rated for 1360 lbs at 50 PSI, with a 24.4″ overall diameter. It fits a 13 x 4.5 inch rim with a 5 lug pattern on 4.5″ centers. DOT-approved components ensure a ready-to-use package with reliable towing performance. Best for smaller boat trailers and harbor-light loads. The 2-year warranty adds value for frequent launches and retrievals.
Who this is best for: boaters with compact trailers, standard 13″ wheels, and a need for simple, ready-to-install assemblies. Choose this if you want a straightforward setup and a solid warranty. Caution: bias ply tires generally ride firmer and may wear differently than radials on uneven launch ramps.
eCustomrim 2-Pack Radial ST205/75R14 14 Inch
This radial tire package supports up to 2040 lbs per tire at 65 PSI and uses a 14 x 5.5 inch rim with a 3.19″ center bore and a 5-lug pattern on 4.5″ centers. It’s DOT-approved and designed for stable towing with higher load capacity, making it a good pick for larger bass boats or deck boats that require better load distribution. The 6-year warranty and roadside assistance provide extended protection for frequent travelers.
Best for: mid-sized boats that demand radial strength and longer wear life. Better for: owners who frequently trailer over rough ramps or long highway legs. Choose this if you want stronger radial performance and a longer warranty period. Limitation: white wheel finish may show dirt more readily in salt air environments unless cleaned regularly.
eCustomrim 2-Pack Trailer Tire Rim ST205/75D15
This bias ply assembly features 1820 lbs load capacity at 50 PSI and a 27.2″ overall diameter on a 15 x 5 inch rim with a 3.19″ center bore. The 5-lug configuration aligns with standard trailer hubs, and the package is DOT-approved for ready-use on most trailer setups. A 2-year warranty with roadside assistance helps protect longer boat trips and weekend getaways.
Best for: larger boats on 15″ wheels with a bias-ply preference. Choose this if you’re upgrading to a bigger wheel size while maintaining a reliable load rating. Caution: bias ply tires can have different wear and heat characteristics compared to radials in hot climates.
eCustomrim Radial ST205/75R14 14 Inch On Rim (Black Spoke)
This radial tire-on-rim assembly has a 2040 lbs per tire rating at 65 PSI, with a 26.1″ overall diameter and a 14 x 5.5 inch black spoke rim. DOT-approved components and a 6-year warranty with roadside assistance support durable performance for frequent trailer use. The black spoke design offers a rugged aesthetic that stands up to salt spray and weather exposure typical of boat launches.
Best for: boat trailers that expect solid radial performance with a sportier rim look. Choose this if you want a modern, corrosion-tolerant rim combined with a high-load radial tire. Limitation: black finish may show scuffs after rough coastal use.
eCustomrim Radial ST205/75R14 14 Inch Wheel (Avalanche Black Aluminum Rim)
This radial tire on a 14 x 5.5 inch avalanche black aluminum rim combines a 2040 lbs load rating at 65 PSI with a 26.1″ diameter. The aluminum rim resists corrosion better than steel, a benefit for saltwater use. DOT-approved assembly includes a 6-year warranty and roadside assistance, enhancing reliability for long trips and off-season storage concerns.
Best for: saltwater boat trailers or coastal use where corrosion resistance matters. Choose this for a lighter, corrosion-resistant wheel without sacrificing strength. Caution: aluminum rims may require regular inspection for corrosion at mounting hardware in very salty environments.
Buying Guide: Key Considerations For Boat Trailer Tires With Rims
- Load capacity: Match tire load rating to your boat’s gross vehicle weight and trailer tongue weight. Higher loads require radial tires with higher PSI ratings when appropriate.
- Rim size and bolt pattern: Verify hub fit, center bore, and lug pattern (common is 5 lug on 4.5″ centers). Incorrect fitment can cause unsafe towing conditions.
- Tire type: Radial tires offer smoother rides and better wear for longer trips; bias ply tires can be cost-effective for smaller or lighter trailers.
- Wheel finish: White wheels may require more cleaning in saltwater areas; black or aluminum rims offer different corrosion resistance and aesthetics.
- DOT approval and warranty: DOT-approved assemblies provide safety certifications, while longer warranties with roadside assistance help on frequent trips.
- Trailer fitment: Check the overall diameter to avoid rubbing on fenders or frame, and ensure the rim width accommodates your tire size.
Frequently Asked Questions
- What does Load Range mean for trailer tires? It indicates the maximum load the tire is designed to carry; choose based on your trailer’s payload.
- Are radial tires better for boat trailers than bias ply? Generally yes for stability and wear, especially on longer trips.
- Do wheel color and material affect performance? Finish and material influence corrosion resistance and maintenance, not tire performance.
- Is DOT approval important for trailer tire assemblies? Yes, it ensures compliance with safety standards and compatibility with common trailers.
