Hi-Run ST100 Trailer Tire
Move your load with confidence. The Hi-Run ST100 is a purpose-built ST trailer tire engineered for stability, durability, and predictable tracking behind your tow vehicle. A sturdy casing manages heat under load, and a balanced tread pattern helps it wear evenly while maintaining grip in wet and dry conditions. Whether you haul equipment, weekend toys, or a work trailer, the ST100 puts safe manners and long service life first.
Note: ST tires are for trailers only and are not intended for passenger vehicles.
Key Features
The Hi-Run ST100 focuses on the fundamentals that matter when you tow. A reinforced casing boosts stability under tongue and axle loads, which helps cut sway and maintain straight-line control. Heat resistant rubber compounds support highway performance and tread life when miles and temperatures climb. The tread promotes steady tracking, clears water in the rain, and keeps contact even to resist irregular wear, while strong sidewalls help resist scrubbing in tight turns.
Technical Specifications Explained
Specs for the Hi-Run ST100 vary by size. Verify the size marking, for example ST205/75R15, along with load range, speed rating, and the maximum cold inflation pressure. Match those numbers to your trailer placard, VIN label, and axle ratings. Overall diameter and tread depth affect clearance and fender fit. If you are replacing bias ply with radial, confirm compatibility and alignment. Torque lugs to spec and recheck after 25 to 50 miles.
Sizes and Fitment Guidance
Start with your trailer certification label or owner manual to confirm the original size, load range, and inflation. Replace with the same size and an equal or higher load capacity, and verify clearance around fenders, brakes, and suspension at full compression, especially on common 13 to 16 inch ST sizes. Match tires on the same axle and consider replacing in sets when wear or age differs. ST tires are not for passenger cars or light trucks, so provide GVWR, axle rating, and current sidewall markings if you need help confirming fitment.
Installation, Maintenance, and Towing Tips
Inflate to the tire's marked cold psi for the load you carry, since underinflation builds heat and shortens life. Balance wheel and tire assemblies, retorque lug nuts after 25 to 50 miles, and check them at routine intervals. Keep wheel bearings and alignment in spec to prevent edge wear, and rotate positions on tandem axles to even out scrub. When storing, keep tires covered, off standing water, and away from ozone sources, and inspect yearly with replacement typically recommended around 3-5 years from the in service date.
Hi-Run ST100 vs Alternatives
Goodyear Endurance is built for sustained highway use and is known for robust construction with higher speed symbols on many sizes. The Hi-Run ST100 targets dependable towing and strong value. If budget matters and your towing is moderate, the ST100 is a smart pick. If you haul heavy loads over long distances, compare speed rating, load index, and warranty details to see which fits your use.
Hi-Run ST100 vs Carlisle Radial Trail HD
Carlisle Radial Trail HD is a go to choice for utility and cargo trailers, with steady wear and broad sizing. The Hi-Run ST100 emphasizes the same fundamentals, stable tracking and practical durability, often at a lower entry price depending on size. Review casing construction, available load ranges, and speed symbols. Choose the tire that meets your axle ratings and expected service profile.
Hi-Run ST100 vs Maxxis M8008
Maxxis M8008 is often chosen for long mile towing and earns praise on travel and boat trailers. The Hi-Run ST100 delivers stable towing and solid value for routine hauling. For cross country trips, look closely at construction details, speed rating, and warranty terms. For regional use and moderate loads, the ST100 may meet your needs at a more accessible price.
Pricing and Value
Price depends on size, load range, and whether you buy tire only or a mounted assembly. Look beyond the sticker, weigh total value including load capacity, speed rating, and expected service life. Replacing in axle pairs helps keep handling consistent. Check current promos, install packages, and ship to home or ship to store options, then enter your size and load range to see availability and lead time before your next trip.
