## Select Tread Pattern For Your Most Common Haul Conditions All trailer tires sold by Tractor Supply meet US Department of Transportation (DOT) safety standards, with a permanent DOT stamp on the sidewall confirming compliance for public road use. For hauling in wet, rainy climates, select tires with deep, wide circumferential grooves that channel water away from the tread surface to reduce hydroplaning risk. For frequent gravel, dirt, or off-road hauling, opt for all-terrain tread with large, interlocking tread blocks and siping to grip loose surfaces and eject stuck mud or debris. For primarily smooth highway hauls, highway tread patterns with minimal tread block spacing reduce road noise and improve fuel efficiency. Never mix tread patterns on the same axle, as this causes uneven wear and unpredictable handling.

How to Select the Right Tractor Supply Trailer Tires for Your Haul
To select the right Tractor Supply trailer tires for your haul, first match the tire load rating to your trailer’s gross vehicle weight rating (GVWR), then choose construction, size, and tread type aligned with your typical haul terrain, distance, and local DOT requirements. Tractor Supply stocks a full range of trailer-specific tires for utility, livestock, equipment, and gooseneck trailers, with fitment guidance available both in-store and online to simplify the selection process. ## Verify Load Rating Alignment With Your Trailer GVWR Your trailer’s GVWR, listed on a manufacturer plate affixed to the trailer frame or in the owner’s manual, is the maximum total weight the trailer can safely carry, including its own empty weight and all cargo. Divide the GVWR by the total number of tires on the trailer to calculate the minimum required load index per tire. For example, a 10,000 lb GVWR dual-axle trailer requires tires with a load index of at least 2,500 each. Always select tires with a load index equal to or higher than this calculated number to avoid blowouts, excessive wear, and handling failure. Tractor Supply’s product listings include full load index specifications for all trailer tires, and in-store associates can help calculate requirements if you do not have your GVWR documentation on hand. ## Choose Tire Construction Based On Haul Type Trailer tires are most commonly sold in bias-ply or radial construction, each suited to different use cases. Bias-ply tires feature multiple layers of rubber-coated fabric plies angled 30 to 45 degrees to the tread, creating stiff sidewalls that resist punctures from sharp debris, handle heavy static loads well, and perform reliably on rough rural roads, gravel, and short off-road hauls. They are also the more budget-friendly option for infrequent or light-duty use. Radial tires have plies that run perpendicular to the tread, with flexible sidewalls that reduce heat buildup during long highway trips, improve fuel efficiency, deliver longer tread life, and provide a smoother ride for sensitive cargo. It is critical to use the same construction type on both tires of a single axle; mixing bias-ply and radial tires on the same axle causes uneven wear and unstable handling. Tractor Supply carries heavy-duty bias-ply tires for livestock and equipment trailers, and radial options for frequent long-distance highway hauling. ## Confirm Exact Size and Rim Compatibility Trailer-specific tires are marked with an ST (special trailer) prefix in their size code (e.g., ST205/75R14), which distinguishes them from passenger (P) or light truck (LT) tires of the same nominal size. ST tires have higher load ratings and stiffer sidewalls engineered specifically for trailer use, even if their size matches a passenger tire. Check the stamp on your existing tire’s sidewall for the exact size, or note your rim diameter, width, and bolt pattern to ensure the new tire fits your existing rims without requiring a full rim replacement. If you are upgrading to a larger tire size, confirm the larger tire will not rub against the trailer fender or frame when the suspension is fully compressed. Tractor Supply’s online fitment tool and in-store staff can cross-reference sizes to match your trailer’s exact specifications.
