Hi-Run SU02 Trailer Tire
Equip your trailer with the Hi-Run SU02, a dependable ST tire built to track straight, run cool, and wear evenly under real-world loads. Whether you haul equipment, a boat, or weekend gear, the SU02 delivers a confident feel on the road thanks to its reinforced construction and all-purpose trailer tread. Choose the right size and load range to match your axle ratings, and expect predictable performance on highways and back roads. For best results, follow the sidewall speed rating, set cold inflation accurately, and keep the trailer within its rated capacity.
Features and Benefits
The Hi-Run SU02 focuses on what matters for trailers, stability, durability, and even wear. Its balanced, non-aggressive tread helps the trailer track straight behind the tow vehicle, and wide shoulders steady the contact patch to resist scrubbing. A reinforced casing and heat-resistant compound manage sustained loads and help the tire run cooler at highway speeds when used within its ratings. Sipes and circumferential grooves move water away to support confident wet-road control, delivering predictable, low-maintenance performance.
Sizes, Load Range, and Fitment
Start with the certification label or owner manual for your trailer. Match the exact ST size, rim diameter and width, and the required load range to meet or exceed the axle GAWR. If you are buying a mounted tire and wheel, also confirm bolt pattern, hub bore, and that the wheel and valve stem are rated for the same pressure as the tire. For tandem axles, use the same size, load range, and speed rating in all positions to keep handling consistent.
Speed Rating and Load Range Explained
Load range indicates the tire's ply rating and maximum pressure, which together set the per-tire weight capacity. Choose a load range that meets or exceeds your calculated requirement and allow a reasonable safety margin. Speed rating defines the maximum sustained speed at which the tire can carry its rated load, many ST tires list an L rating at 75 mph, but always follow the symbol on your SU02 sidewall and the lowest limit among tire, wheel, and trailer guidance. Proper cold inflation is essential to achieve the published load and control heat.
Pricing and Value
The Hi-Run SU02 delivers dependable towing performance at a wallet-friendly price. Value improves when the load range matches your needs and pressures are maintained precisely, which helps prevent premature wear. Look for options that include mounting, new valve stems, and balancing if you choose a wheel assembly. If you tow often, consider replacing tires in axle sets and bundle a spare, covers, and a quality gauge at checkout.
Real-World Reviews and Use Cases
Owners choose the Hi-Run SU02 for utility, cargo, and boat trailers that need steady tracking and simple maintenance. Feedback often highlights calm highway manners when the tire is run at the listed cold pressure and within rated loads. The tread is tuned for long, even wear on pavement, not off-road grip, making it a strong match for road trips and ramp approaches. For seasonal use, store cool and out of sun, and for heavy interstate miles, verify your size's speed rating and keep inflation spot on.
SU02 vs Other Trailer Tire Options
Trailer tires differ by construction, load range, and duty cycle. The Hi-Run SU02 is geared for everyday towing with straight-line stability and even wear on pavement. Some ST choices prioritize higher speed symbols or heavier load ranges, while others save weight or pair with corrosion-resistant wheels. Choose based on your routes, gross trailer weight, and climate, and if you run fully loaded in heat, focus on the correct load range, accurate cold inflation, and an appropriate speed rating.
SU02 vs Radial ST Tires
Radial ST tires tend to run cooler at sustained speeds and often wear more evenly on long highway trips, while other constructions can favor rugged casing support for short-haul or mixed-use towing. The Hi-Run SU02 is built for stable towing and dependable wear when used within its ratings. If most of your miles are on the highway, confirm your size's speed symbol and maintain exact cold inflation to manage heat. For mixed speeds or frequent launching, consistent maintenance, pressure checks, inspections, and timely replacement, usually has a bigger impact than construction alone.
Installation, Maintenance, and Safety
Have the Hi-Run SU02 mounted by a qualified technician using wheels and valve stems rated for the tire's maximum pressure. Inflate to the sidewall-listed cold pressure unless your trailer maker specifies otherwise, check pressure before each trip, and torque lug nuts to spec, then recheck after 25 to 50 miles. On tandem axles, rotate positions as needed to promote even wear and follow any directional markings. Replace tires that show cracking, bulges, sidewall or shoulder damage, or worn tread, and store them off the ground in a cool, dry, shaded place.
