ST175/80R13 Trailer Tire for Utility and Light Commercial Applications

The ST175/80R13 trailer tire is a special trailer (ST) radial tire designed specifically for light-duty trailers, utility trailers, small cargo trailers, boat trailers, and camper trailers. Unlike passenger or light truck tires, ST tires are engineered with reinforced sidewalls and higher load-carrying capacity to support the vertical weight demands of trailer applications.

If you are asking:

• What is this tire used for?
  The ST175/80R13 is used exclusively for trailer axles, not for drive or steer positions on powered vehicles.

• Is this suitable for my trailer or fleet?
  This size is commonly fitted on small enclosed trailers, landscaping trailers, single-axle cargo trailers, boat trailers, and light equipment transport trailers. It is ideal for commercial operators, rental fleets, and logistics companies operating light trailer units.

The ST175/80R13 provides stable highway performance, predictable tracking, and reliable load support, making it a dependable solution for both private and commercial trailer use.

 Performance & Technical Benefits

✔ Load Carrying Capability

The ST175/80R13 is engineered to support higher vertical loads compared to similarly sized passenger tires. Its reinforced casing design allows safe transport of cargo while maintaining structural integrity under continuous highway use.

✔ Mileage Potential

The tread compound is formulated for even wear across the contact patch, helping reduce irregular wear and extending usable tread life in commercial applications.

✔ Stability and Tracking

Trailer tires must maintain stable alignment behind the towing vehicle. This size offers:

• Predictable straight-line tracking

• Reduced sway under load

• Balanced footprint for stable highway operation

✔ Rolling Resistance & Efficiency

The radial construction supports lower rolling resistance compared to older bias designs, contributing to improved towing efficiency and reduced fuel strain on the towing vehicle.

✔ Casing Strength & Retreadability

The durable internal structure enhances resistance to:

• Heat buildup

• Sidewall flex fatigue

• Load-induced stress

This improves safety and extends the overall service life of the tire in fleet environments.
