Free Country Trailer Tire Wheel Assembly ST175/80D13 - Durable 8-Ply

In this review the Free Country Trailer Tire Wheel Assembly ST175/80D13 is evaluated for trailer owners who need a durable, ready-to-mount wheel and tire combo. The bottom line: this assembly is aimed at enclosed trailer and light utility trailer users who want a higher tread depth and an 8 ply, Load Range D tire that can carry heavier loads safely while offering better longevity than bargain options. It is a straightforward replacement that saves time fitting a rim and tire separately and gives confidence for routine hauling.

Key Features

• Deeper tread: The 7mm tread depth provides longer wear life and better mileage compared with many competitors that list around 5.6 mm.
• Heavy duty rating: An 8 ply rated, Load Range D construction supports higher loads and tougher towing conditions for heavier trailer use.
• Load capacity: With a Load Index of 96 the tire supports substantial cargo weights, making it suitable for many enclosed and utility trailer applications.
• Pre-mounted wheel: The 5 lug on 4.5' bolt pattern wheel with offset 0 and white spoke style arrives ready to mount for quick installation.
• DOT certified: Meets or exceeds applicable DOT standards so it can be relied on for safe hauling season after season.

Who It's For

This assembly is best for trailer owners replacing worn trailer tires who want a ready-made option that balances durability and value. It suits owners of small enclosed trailers, utility trailers, and boat trailers that use ST175/80D13 tires and a 5 lug on 4.5' PCD wheel pattern.

Those who need high-speed highway touring or heavy commercial use beyond the stated speed rating and load range should look at higher-speed or higher-load specialty tires. Also confirm fitment with your owner's manual, as the fitment guide is for reference and not a guaranteed fit for every model.

Pros & Cons

Pros

• Good build quality with customers noting the assembly holds up well in regular trailer use.
• Better tread depth than many budget alternatives, which translates to longer service life.
• Convenience and appearance of a pre-mounted white spoke wheel that fits common trailer hubs with a 5 lug on 4.5' PCD.
• DOT safety certification and an 8 ply, Load Range D rating for dependable load carrying.

Cons

• Speed rating L limits sustained speeds to around 75 mph, so it is not intended for higher-speed applications.
• Fitment should be double-checked against the trailer's manual since the guide is not a guaranteed match for every vehicle.
