ECOTRIC Set of 2 13-Inch Trailer Fenders
Best for: Single-axle trailers with 13″ wheels. These fenders provide solid protection with a built-in skirt design and a 300-lb capacity. They are a straightforward fit for common boat trailers and offer an economical choice for replacing worn fenders. Consider if you need a dual-fender solution that aligns with standard 13″ wheel assemblies.
Caution: Check wheel diameter and mounting spacing before purchase to ensure compatibility with your trailer frame, as some trailers require different mounting brackets.
Tie Down Black Plastic Fender For Small Wheels (2 Pack)
Best for: Trailers with compact wheels around 5.19″ overall diameter. The fenders are UV-protected and designed to resist fading and cracking, making them long-lasting in harsh outdoor conditions. This option is ideal for smaller boats or utility trailers with tight wheel wells.
Caution: Verify overall tire diameter on your trailer; these fenders are sized for roughly 5.19″ tires and may not fit larger wheels.
ECOTRIC 2 Pcs Fenders with Steps for 13″ Wheels
Best for: Single-axle trailers with 13″ diameter wheels seeking added utility from built-in steps. The HDPE construction and built-in fender skirt provide a finished look and reliable protection against road debris. Choose this if you value convenience and a two-fender kit with steps.
Caution: Confirm the wheel diameter and overall width of your tires; ensure there is adequate clearance for the step feature on your trailer model.
Tie Down 13-Inch Wheels Fender Set (2 Pack)
Best for: Trailer owners needing a durable, single-axle fender with a classic, single-wheel design. The ABS resin construction emphasizes long-term resilience in varied weather, making it a practical addition to many trailers.
Caution: This fender is designed for single-wheel use; do not pair with overlapping wheel configurations that exceed the stated dimensions.
HECASA 8″-12″ Skirt Fenders with Top Step
Best for: Single-axle trailers with 8″-12″ wheels needing a skirt and top-step feature. The HDPE material and integrated skirt help protect wheels and provide a neat trailer finish. This option suits boats with mid-range wheel sizes and a preference for a sleek appearance.
Caution: Measure tire diameter and width to ensure the fender’s span and width will not contact the tire or frame during loading and steering.
Buying Guide
What wheel size does your trailer use?
Choose fenders sized to match your trailer’s wheel diameter and width. Mismatched fenders can fail to shield wheels properly or interfere with tires during turns.
Material and durability
HDPE is common for outdoor trailer fenders due to impact resistance and weather resistance. ABS resin is another durable option for single-wheel designs. Consider UV protection and resistance to cracking in your climate.
Built-in features
Fender skirts, top steps, and integrated skirts add utility and aesthetics. Decide whether you need protection from road debris, a convenient step, or a cleaner trailer look.
Fitment and mounting
Confirm mounting hole patterns, overall dimensions, and the number of fenders required. Some options are sold as a pair; others suit a single wheel. Check the trailer’s mounting brackets and spacing before purchase.
Best use cases
For small or compact trailers with 5.19″ or similar wheel diameters, choose Tie Down options. For standard single-axle boats with 13″ wheels, ECOTRIC and Tie Down 13″ models are reliable. If you want a built-in step or a skirt for added protection, select models offering those features.
