ST175/80D13 Bias Trailer Tire and 13in White Wheel Assembly - Durable

In this review of the ST175/80D13 bias trailer tire and 13in white wheel assembly, the bottom line is straightforward: this set is for trailer owners who need a tough, DOT-compliant tire-and-rim combo rated for moderate towing loads. The reviewer found the assembly delivers predictable handling and strong load capacity thanks to its 6-ply construction and reinforced rubber with double-steel belt construction. For anyone replacing worn trailer wheels or building a spare, the included rim and clear load specs make installation and specification matching fast and reliable.

Key Features

• Complete tire-and-wheel assembly: Arrives with a 13in x 4.5in white rim already mounted, so it is ready to install on trailers that use a 5 on 4.5in bolt pattern.
• Rated load capacity: The tire is Load Range C with a max load per tire of 1350 lbs at recommended pressure, which gives reliable carrying capacity for small to medium trailers.
• Bias ply construction: Thick nylon cords set in a crisscross pattern deliver stiffer sidewalls and improved shock absorption for trailer use on rough roads.
• DOT compliant and durable: The ST175/80D13 meets Department of Transportation specifications and uses a double steel belt for added strength and towing stability.
• Clear fitment details: Key dimensions such as overall diameter ~24in, section width ~6.97in, center bore 3.19in and hub diameter 6.5in make it straightforward to confirm compatibility with existing hubs.

Who It's For

This assembly is a good fit for owners of utility trailers, boat trailers, and small campers that specify ST175/80D13 tires and a 5 on 4.5in bolt pattern. It is aimed at buyers who prefer a ready-to-mount tire with a rim included so they can swap a full wheel quickly without separate mounting costs.

It is not intended for heavy-duty commercial hauling beyond the stated load limits or for applications that require higher speed ratings. Shoppers needing a higher load range or a radial trailer tire should look at other options.

Pros & Cons

Pros

• Ready-to-install wheel and tire reduces time and effort for replacements.
• Load Range C 6-ply construction and double steel belt enhance towing stability and durability.
• Clear, concrete specs (OD ~24in, section width ~177mm, bolt pattern 5 on 4.5in) simplify fitment checks.
• DOT compliant for legal and safe road use.

Cons

• Bias ply tires have stiffer sidewalls and are less efficient on fuel than radials, so they are a trade-off for durability over ride economy.
