Features to know about
Built for Steady Hauling: Load Range B with 1,100-lb Capacity at 35 psi
When you're carrying gear or equipment that pushes the limits, you need a tire that can handle it without flexing under pressure. The Loadstar ST175/80D13 Bias Trailer Tire delivers a 1,100-lb maximum load at 35 psi with a 4-ply (Load Range B) rating. It's been rigorously tested to exceed Department of Transportation standards so you can tow with confidence knowing it's built for real hauling.
Stable Handling Where It Counts: Flatter Tread and Strong Sidewalls
A flatter tread profile helps this tire track straight and stay planted on the road, even when loaded down. Its sturdy sidewalls are designed specifically for trailer use, providing the support needed for heavy loads without compromising stability. That combination adds up to confident handling and a smoother feel on the highway or in tight turns.
Smooth Ride Over Rough Terrain: Bias Ply Construction with Nylon Cords
The bias ply build is tough where it counts. Layers of thick nylon cords are set at a 30- to 45-degree angle and crisscrossed for strength, giving the entire tire uniform flex and durability. Those reinforced sidewalls soak up bumps and help maintain control across uneven surfaces, making towing on back roads or gravel feel more predictable.
Confidence Backed by Warranty: 5-Year Limited and 1-Year Worry-Free Guarantee
It's one thing to say a tire is tough-it's another to back it up. This Loadstar tire includes a 5-year limited warranty plus a 1-year worry-free guarantee that covers replacement if it's damaged in the first 12 months. It's reassurance that this tire is made to last through season after season of towing.

- Option to Replace 155/80-13 Size Trailer Tires
If you go up to 175/80-13 sized tires, like # they will be about 1-1/2 inches larger in diameter and about 1/2 inch wider. You want at least 3 inches between the tread and fender and an inch between the sidewall to the inside of the wheel well. If you have the clearance it will be better to go with the larger tire than the smaller. If you go down to the 145/R12, like # AM35354, or the 5.30-12 like # AM35354, you'll have tires that are about an inch smaller in diameter and about a 1/2...

- Can You Upgrade ST175/80D13 Tires On Utility Trailer
In order to determine if you can upgrade tire sizes you'll need to measure for clearance. We recommend 3" on top and 1" inside the existing tire. If you have more than this then you can move up a size, the next largest would be a 185/80-13 such as the Castle Rock ST185/80R13 Radial Trailer Tire part # LHCK105 (24.6" Diameter x 7.2" Wide). If not it's best to stick with the same size you have such as the Loadstar ST175/80D13 Bias Trailer Tire part # AM1ST74 (24" Diameter x 6.6" Wide).

- What Trailer Tire Size is the Right Replacement for A78-13 Tires
By definition an A78-13 tire cannot be mounted on a 14 inch wheel since it is a 13 inch tire. Wheel diameter is tricky. When measuring them you do not actually measure the total height of the wheel so you likely have 13 inch wheels. A78-13 is an old way of indicating a tire size. The metric equivalent is ST175/80-13. Since you have a 5 lug wheel it is likely a 5 on 4-1/2 inch bolt pattern. You can measure by following the help article I have linked for you. But if you just need tires...

- What Does Trailer GVWR Mean for Maximum Cargo Weight Capacity and Can it Be Increased
When a manufacturer indicates a trailer's GVWR, which is the most it can ever weigh under any circumstances, this consists of the weight of the empty trailer itself plus the maximum cargo weight you can put in it. Under no circumstances do you want the loaded trailer to weigh more than the manufacturer's rated GVWR. Sometimes trailer makers may install axles whose combined rating is not exactly the same as the specified GVWR. The total axle capacity could be more than or slightly less...

- Trailer Tire Replacement for Size A-78-13
Since your trailer uses lug bolts to secure the wheels to the hubs that means the hubs are hub-centric which means that the pilot hole of the wheel is what centers the wheel to the hub.

The metric equivalent of an A78-13 tire is a 175/80-13. This size is available in load range B, # AM1ST74, rated for...
