Hercules Strong Guard ST Trailer Tire
Put a purpose-built tire under your trailer. The Hercules Strong Guard ST is a special trailer, ST, radial that delivers steady tracking, confident handling, and durability under load. Reinforced construction helps control sway and resists heat buildup on long hauls, and the tread design promotes even wear for consistent performance. With popular sizes and load ranges, it's a smart, value-minded fit for travel trailers, cargo, boat, and utility trailers. Choose the Strong Guard ST when you want straightforward towing confidence without overspending.
Features that support stable, reliable towing
The Strong Guard ST is built for trailers, with steel-belted radial construction and reinforced sidewalls that help limit sway and improve tracking. A heat resistant compound is formulated for sustained highway speeds and heavy loads, helping the tire run cooler when properly inflated. A solid center rib boosts straight-line stability, and sturdy shoulders resist scrubbing in tight turns. Optimized tread geometry keeps even contact and predictable wear, so performance stays consistent over the life of the tire. Together, these elements deliver dependable control and durability for a wide range of towing needs.
Sizes, load ranges, and key specifications
Choose from popular ST sizes such as 205/75r14, 205/75r15, 225/75r15, and 235/80r16, with multiple load ranges to match your trailer's requirements. Common options include Load Range D, 8-ply rating, and E, 10-ply rating, with select sizes available in higher capacities. Check the sidewall for exact load index, maximum psi, and speed rating, and match or exceed the specifications on your trailer's certification label or in the owner's manual. For best results, maintain proper inflation and leave a margin of reserve capacity between your trailer's maximum weight and the tires' combined load rating.
Real-world performance and durability review
On the road, the Strong Guard ST focuses on what matters to trailer owners, tracking stability, heat control, and even wear. The reinforced build supports steady lane holding and reduced sway, especially with proper tongue weight and correct cold inflation. A heat resistant compound helps the casing run cooler under sustained loads, which supports long service when used within rated limits. The tread's solid ribs encourage even wear and predictable performance mile after mile. While ride comfort depends largely on the trailer's suspension, you can expect steady, no nonsense towing from a value forward ST tire like this.
Price and value for your towing setup
The Hercules Strong Guard ST is priced to deliver strong value while covering the fundamentals of safe towing. Durable construction and an even-wearing tread can extend service life when inflation, load, and speed are managed correctly, reducing long-term costs. With accessible pricing, multiple load ranges, and widely available sizes, it is an easy upgrade over aging or mismatched trailer tires. For an exact price, select your size and load range, and consider new valve stems and professional mounting for the best long term results.
Hercules Strong Guard ST vs Goodyear Endurance
Choosing between the Strong Guard ST and Goodyear Endurance often comes down to budget, availability, and the size or load rating you need. The Strong Guard ST delivers dependable, trailer focused construction at a value price with many popular sizes covered. The Endurance is a premium ST option, typically priced higher, with broad size coverage and a strong reputation among frequent haulers. Both are designed for trailer use only. If cost effective reliability is the priority, the Strong Guard ST is compelling. If you want a premium nameplate and are willing to spend more, the Endurance is worth a look.
Maintenance tips for longer tire life
Maximize the life of your Strong Guard ST with simple habits. Inflate to the cold psi listed on the tire sidewall and recheck before trips. Keep loads within the tires' combined capacity, and distribute weight to maintain proper tongue weight. Observe the speed rating on the sidewall and the trailer manufacturer's limits. Inspect for irregular wear, cuts, bulges, or embedded objects, and replace in sets when wear or age becomes a concern. Store the trailer on clean, dry surfaces, use covers if parked outdoors, and move it periodically during long storage to help avoid flat spotting.
Speed rating and load index explained
Every Strong Guard ST lists a speed rating, for example L or M, a load index, and maximum psi on the sidewall. Match these to, or exceed, the specifications on your trailer's certification label, and never downgrade from the original equipment rating. The speed rating is the maximum tested speed for the tire. Staying under that limit, maintaining correct pressure, and avoiding overload are key to managing heat. The load index corresponds to maximum carrying capacity at a specified psi. When in doubt, choose the load range that provides adequate reserve capacity for your fully loaded trailer.

Do you have a question about Strong Guard ST ST175/80R13/6 91/87N?
The Hercules Strong Guard ST tires are designed for use on trailers, providing optimal performance for towing applications. Their construction ensures smooth handling and stability when being towed.
The Strong Guard ST is built for trailers and should be used only on trailers, not on passenger cars or light trucks. It suits travel trailers, cargo and utility trailers, boat trailers, and equipment haulers when sized and rated correctly. Confirm your original equipment size, load range, and speed rating on the trailer's certification label or in the owner's manual. Choose a tire that meets or exceeds those specifications, maintain proper inflation and weight distribution, and if you tow near maximum capacity, consider a higher load range for added reserve.
Common sizes include 205/75r14, 205/75r15, 225/75r15, and 235/80r16, with multiple load ranges to support different trailer weights. Many applications use Load Range D, 8-ply rating, or E, 10-ply rating, and select sizes may be offered in higher capacities. Availability varies by region and inventory, so confirm the exact size, load index, and psi for your trailer. Always match or exceed the specifications on your trailer's certification label to maintain safety margins and compliance.
Speed ratings are size dependent and are molded on the tire's sidewall, for example L or M. Always adhere to the lower of the tire's speed rating and the trailer manufacturer's maximum recommended speed. Exceeding either limit can cause excess heat, which is a leading factor in trailer tire failure. Before trips, check cold inflation pressure, balance your load, and keep speeds conservative on hot days or when fully loaded. If you need higher speed capability, verify availability in your exact size and consult your retailer for the right option.
Like most special trailer, ST, tires, the Strong Guard ST typically does not include a treadwear mileage warranty. It is usually covered by a limited manufacturer warranty against defects in materials and workmanship for a defined period. Coverage terms can vary by retailer and region, so review the warranty booklet and keep proof of purchase. You'll get the best life by maintaining proper inflation, not exceeding load capacity or speed rating, rotating positions if your trailer allows, and replacing tires that show damage, irregular wear, or advanced age.
Start with the trailer's certification label to find the required tire size and minimum load range. Add up the load capacity of all trailer tires and ensure it exceeds your trailer's maximum loaded weight, leaving a margin of reserve capacity. If you tow near maximum weight frequently, stepping up to a higher load range can provide additional headroom. Maintain the cold psi specified on the tire sidewall to achieve the rated capacity. When changing sizes or load ranges, consult a tire professional to verify fitment, wheel compatibility, and fender clearance.
