Hercules H-901 ST Trailer Tire
Built for serious towing, the Hercules H-901 ST is a special trailer radial designed to haul heavy loads mile after mile. Its ribbed tread helps the trailer track straight and promotes even wear, while a heat-managing compound keeps performance consistent at sustained highway speeds. RV, cargo, equipment, and boat trailer owners value its stable feel and long service life when it is kept at the correct pressure. Choose the size and load range that match your axle ratings for dependable towing every trip.
Key Features
The Hercules H-901 ST focuses on stability, heat control, and durability. A straight rib pattern maintains a steady footprint for confident tracking and more even contact with the road. Heavy-duty construction supports high load ratings and resists flex under weight, which helps braking and control. A heat resistant compound and reinforced shoulders spread stress across the tread, aiding mileage when the tire is properly inflated.
Sizes, Load Ranges & Specs
The H-901 ST comes in popular ST sizes to cover a wide range of trailers, including ST225/75R15, ST235/80R16, and ST235/85R16. Depending on size, you will see higher load ranges such as F, often called 12-ply, and G, often called 14-ply, for heavier RV and cargo use. Always confirm the load index, load range, and speed symbol on the product page and on the sidewall, since they can vary by size and production run. Match your choice to the trailer certification label and axle ratings, and use wheels with the correct diameter, width, and bolt pattern.
Popular Sizes & Fitment Guidance
Many shoppers pick ST225/75R15 for lighter tandem-axle trailers, and ST235/80R16 or ST235/85R16 for heavier RVs and cargo haulers. When comparing options, look at three things, size that matches your wheel, load range for the weight you carry, and the tire speed rating. If your trailer came with a specific size and load range, replace with equal or higher load capacity. Before mounting, check fender clearance and spacing between duals if used, and keep all tires on the same axle identical in size and load rating.
Performance for Towing
On the highway the Hercules H-901 ST delivers steady, predictable towing. The ribbed tread helps reduce sway by keeping the footprint stable, and the robust build controls heat when inflated to the recommended pressure. Braking remains consistent because the tire maintains contact across the tread. For best results, set cold inflation to spec, balance assemblies, and maintain alignment and weight distribution.
Reviews: What Owners Say
Owners often praise the H-901 ST for solid highway stability and good tread life when it is inflated correctly. Many also report a planted feel with heavier loads and fewer heat related issues at proper pressure. As with any ST tire, underinflation or overloading can shorten life or cause damage. If you are moving up from a lighter load range, matching a higher load range to your trailer needs can improve stability, but always compare size, load, speed symbol, and warranty terms before buying.
Price & Availability
Price depends on size and load range, with larger diameters and higher ply ratings costing more. Seasonal demand and regional supply can affect lead times. Compare total installed cost, including mounting, new valve stems, balancing if used, disposal, and any road hazard coverage. When ready to buy, order the exact size and load range your trailer requires and try to source a matched set for consistent date codes across the axle.
H-901 ST vs Other Trailer Tires
Shoppers often compare the Hercules H-901 ST with other heavy duty ST choices, such as the Sailun S637 in similar sizes and load ranges. The right pick comes down to required load capacity, speed rating, price, and availability in your area. Review construction details, warranty terms, and dealer support for each option. If you tow fast or in hot climates, prioritize heat resistance and correct inflation, and for heavier fifth wheel or cargo trailers focus on load index and recommended pressure.
Maintenance & Care Tips
Check cold inflation before every trip and adjust for load. Do not exceed the rated load or the speed symbol shown on the sidewall. Service wheel bearings, torque lug nuts, and keep the trailer aligned to prevent irregular wear. Inspect tread and sidewalls for cuts, bulges, or punctures, rotate across axles if your trailer allows, and store on level ground out of direct sun when possible. Quality valves and accurate TPMS monitoring further enhance safety and tire life.
