ST175/80D13 Trailer Tires Set of 2 - Heavy Duty 8PR Load Range D

In this review of the ST175/80D13 trailer tires set, the bottom line is straightforward: these are a value-oriented option for owners who need a robust, bias-ply trailer tire that fits 13 in rims and carries heavy loads. The reviewer found the pair useful for utility trailers, small boat trailers, and light equipment transport because of the 8 ply heavy duty construction and a respectable 1,570 lb maximum load per tire at 65 psi. They are brand new, unmounted, and backed by a one year limited distributor warranty, which makes them a sensible replacement choice for routine trailer needs.

Key Features

• Set of two: Sold as a matched pair so buyers can replace both sides and restore balanced handling on a twin-axle or matched single-axle setup.
• Heavy duty 8PR bias construction: The bias ply design with 8 ply rating provides durability for loaded trailer use and a sturdier sidewall for towing conditions.
• High load capacity: Each tire is rated to carry up to 1,570 lbs at 65 psi, suitable for many small trailers and everyday hauling tasks.
• Deeper tread for longer life: The VR383 pattern offers enhanced tread depth to extend service life compared with thinner trailer tires.
• One year limited warranty: The distributor warranty gives buyers some protection against early defects and provides added confidence in the purchase.

Who It's For

The ST175/80D13 set is best suited to owners of utility trailers, small boat or fishing trailers, landscaper trailers, and small cargo trailers who need a cost-effective, heavy duty replacement tire that mounts on a 5 in rim. It is also a fit for fleet or commercial buyers who prefer buying in sets for scheduled maintenance.

Those who haul very high-mileage loads on the highway, require radial tire comfort, or need specialized trailer tires for extremely heavy loads should look elsewhere; this is a bias-ply, trailer-only tire optimized for load capacity and durability rather than long high-speed highway comfort.

Pros & Cons

Pros

• Good value for money with solid build and useful load rating for small to medium trailers.
• Deeper tread and 8 ply rating improve expected service life under typical trailer loads.
• Sold as a pair and supplied brand new, unmounted, with a distributor warranty included.

Cons

• Some customers reported early tire damage or separation in isolated cases, so buyers should inspect tires on delivery and monitor early mileage.

Specifications

Our Verdict

The ST175/80D13 pair is recommended for trailer owners who need a dependable, heavy duty replacement that balances load capacity and cost. With an 8PR bias construction, deeper tread, and a one year distributor warranty, it is a sensible, value-focused choice for utility and boat trailers, provided buyers inspect for any shipping damage and are comfortable with bias-ply behavior rather than radial comfort.
