Buying Guide: ST205/75D15 Tire And Rim Essentials
What to consider when selecting a tire and rim assembly for a trailer:
- Tire construction and rating: ST tires are bias ply by design and typically rated by load range (A, B, or C) with a maximum PSI. Choose Load Range C for most utility trailers that require steady towing and predictable wear.
- Rim size and bolt pattern: Most ST205/75D15 setups use a 15X5 inch rim with a 5-lug, 4.5″ bolt pattern. Confirm center bore compatibility to ensure proper seating and lug alignment.
- Overall diameter: Approximately 27.2 inches for these tires. Ensure your trailer’s fenders and clearance accommodate this diameter to avoid rubbing.
- DOT approval: DOT-approved assemblies come with safety assurances and standardized manufacturing practices, aiding inspection and compliance.
- Warranty and roadside assistance: A 2-year warranty with roadside support adds value for on-the-road reliability, especially for frequent travelers or fleet operators.
- Rim finish and color: White or black rims affect aesthetics and maintenance. White wheels may require more cleaning, while black rims tend to hide dirt better.
- Rims included or not: Some packages include rims, while others provide tires only. Factor in the need for compatible rims you already own or plan to buy.
