Trailer Tire Wheel Assembly ST175/80D13 6-Ply 5-Lug White Spoke

In this review the reviewer tested the Free Country trailer tire wheel assembly to judge durability and fit for light trailers and utility hauling. The bottom line: this set of two assemblies is aimed at trailer owners who need a tougher, longer-lasting tire than bargain alternatives, with a practical white spoke wheel that matches common 5-lug 4.5' bolt patterns. Its single biggest selling point is the deeper 7mm tread on a 6-ply, load range C tire that promises longer mileage and dependable cargo hauling.

Key Features

• Deeper tread: The 7mm tread depth delivers improved wear life compared with many cheaper trailer tires, which helps extend replacement intervals.
• 6-ply construction: The 6 ply rating and Load Range C provide a tougher carcass for hauling moderate loads and resisting punctures.
• Load and speed ratings: With a Load Index of 91 and speed rating L, each tire supports up to 1360 lbs and is rated for up to 75 mph for highway towing within limits.
• Wheel fitment: The white spoke wheel is a 5 lug on 4.5' PCD with zero offset, matching many common trailer hubs for straightforward installation.
• DOT safety certification: Meets or exceeds applicable DOT standards so buyers can rely on consistent, season-to-season performance for hauling cargo.

Who It's For

This wheel assembly is best for owners of small trailers, utility trailers, or boat trailers who want a robust, longer-wearing alternative to economy trailer tires. It suits users who value load capacity and a simple white spoke wheel design and who typically carry moderate cargo loads within the stated 1360 lb per-tire limit.

It is less appropriate for heavy commercial trailers, high-speed travel well above 75 mph, or applications that require specialized rims or uncommon bolt patterns; those users should seek higher load ranges or wheels matched exactly to their hub specifications.

Pros & Cons

Pros

• Durable 7mm tread offers longer mileage life versus thinner-tread competitors.
• 6 ply, Load Range C construction improves resistance to damage under typical trailer loads.
• Wheel is a common 5 lug on 4.5' PCD with a clean white spoke look that fits many trailers.
• DOT certified for dependable seasonal performance when properly maintained.

Cons

• Speed rating L limits sustained travel to 75 mph, so it is not suited for high-speed towing at higher limits.
• Fitment guide is for reference only; customers must confirm fit with their owner manual before purchase.
