Hercules Strong Guard C-ST Trailer Tire
Tow with confidence. The Hercules Strong Guard C-ST is a purpose-built ST radial engineered for stability, heat control, and durability under heavy loads. A reinforced casing helps the tire track straight and limit squirm, and a heat-resistant compound promotes cooler running at highway speeds. Whether you haul a camper, boat, or work trailer, the Strong Guard C-ST delivers dependable miles with sizes and load ranges to match your GVWR.
Key Features & Benefits
Built for trailer duty, the Strong Guard C-ST focuses on what matters when towing. A reinforced casing and robust sidewalls help control sway and maintain straight-line tracking under load. The tread pattern promotes even wear and reduces heat buildup for longer service life, and a solid center rib adds stability while wide grooves move water away in the rain. Multiple load ranges let you match capacity to your trailer's GAWR.
Sizes, Load & Speed Ratings
Popular Strong Guard C-ST sizes include ST205/75R14, ST205/75R15, ST225/75R15, and ST235/80R16, with several load ranges by size. Always match or exceed your trailer's certification label for size, load index, load range, and speed rating. ST tires are engineered for trailer axles only, not for passenger vehicles. For exact capacity and speed symbol by size, check the spec sheet or sidewall, then set pressure using the tire's load-inflation table.
Pricing & Where to Buy
Pricing for the Hercules Strong Guard C-ST varies by size and load range, and higher capacity versions typically cost more due to stronger construction. Select your size and load range and add to cart for an instant quote. For best stability and wear, purchase in axle pairs. If you would like help, share your GAWR and tire size and we will confirm fitment and provide a delivered or installed price where available.
Installation & Maintenance Tips
For best results, install trailer tires in axle pairs, confirm rim width and wheel load rating, and use valve stems that match the required pressure. Balancing helps reduce vibration and promotes even wear. Inflate according to the tire's load-inflation chart for your actual load, not passenger-car guidelines. Re-torque lug nuts after 25 to 50 miles and inspect before trips, and store the trailer out of direct sun when possible.

Match those details to your trailer weight and driving pattern to find the best overall value.
