eCustomrim 2-Pack Trailer Tire Rim Assembly 4.80-12
Product details indicate a bias ply trailer tire rated for 990 lbs with a maximum 60 PSI. The 20.5″ overall diameter and Load Range C suit smaller boat trailers and light utility trailers.

Best for budget-conscious buyers who need a straightforward, reliable shore-to-boat option. Caution: Bias ply tires can wear faster in high-speed or aggressive driving conditions compared to radials.
Who it’s best for: Small to mid-size trailers that prioritize affordability and straightforward installation. It’s a solid choice for casual boat trailers or utility setups that don’t demand aggressive high-speed performance.
Why selected: The complete tire assembly with DOT approval and roadside warranty adds reassurance for occasional marine travel and transport tasks. The 4.80-12 size is a common fit for compact trailers, and the 5x lug pattern aligns with many boats and utility trailers.

Buying Guide
What size should I choose for my boat trailer?
Match the tire size (for example, 4.80-12, ST205/75R14, ST235/80R16) to your trailer’s axle rating, wheel wells, and user manual. Larger tires can improve load distribution and ride quality on bigger trailers but require compatible rims and hub spacing.
Bias ply or radial tires—what’s better for boats?
Radial tires generally offer smoother handling and longer tread life on highway towing, making them a good fit for frequent highway travel. Bias ply tires can be adequate for light use and cost-conscious buyers but may wear differently and deliver a stiffer ride.
How important is the rim pattern and bolt pattern?
Ensure the rim’s bolt pattern (for example, 5 Lug On 4.5″ or 8 Lug On 6.5″) matches your trailer hub. Mismatches require adapters or different rims, increasing cost and complexity.
What warranty and support should I expect?
Look for assemblies with DOT approval, a manufacturer warranty, and roadside assistance. These features provide a safety net for unexpected flats or roadside issues during trips.
Are 6-ply or 8-ply tires worth it for my trailer?
Higher ply ratings (6PR, 8PR) are beneficial for heavier trailers and frequent hauling. They typically offer improved load-bearing capacity and durability, but check your trailer’s axle and suspension limits to avoid overloading.
What are common cautions to consider?
- Verify hub bore size and center bore alignment to ensure proper seating.
- Check inflation pressure and load rating to prevent underinflation or overloading.
- Inspect sidewalls for damage and ensure tires are DOT-approved for safe use.

FAQ
- Q: Do I need a matching brand for tire and rim?
- A: Not necessarily, but matching sizes and bolt patterns are essential for safe mounting and balance.

- A: Check tread depth and sidewall condition regularly; replace when tread approaches 2/32″ or if there are signs of cracking or bulging.
