Power King Premium Trailer ST Bias Ply Trailer Tire

The Power King Premium Trailer is an ST-rated (Special Trailer) bias ply tire engineered exclusively for towed trailer service. Trusted by trailer owners across a wide range of applications — including utility trailers, cargo trailers, boat trailers, and general-purpose hauling — this tire delivers a dependable combination of load-carrying performance, all-weather capability, and road hazard durability at a practical price point.

ST-Rated for Trailer Use Only

The ST designation means this tire is purpose-built for trailer axles only and must not be mounted on passenger vehicles or light trucks. This specialized construction, load rating, and performance profile is fully optimized for the unique demands of being towed — including sustained static loads, extended stationary storage periods, and variable towing speeds.

Bias Ply Construction

The bias ply casing features multiple layers of plies crisscrossed diagonally from bead to bead, producing a stiffer sidewall and a rigid overall structure. Compared to radial tires, this thicker sidewall construction gives the Premium Trailer enhanced resistance to punctures, cuts, road hazards, and potholes. The reinforced bias ply structure also maintains tire shape under heavy load and towing pressure, supporting strong overall load capacity without deformation.

All-Weather Tread Performance

The grooved circumferential rib tread pattern is engineered for consistent road contact on paved surfaces, making it well-suited for highway hauling and general towing use. Circumferential and lateral grooves work together to channel water away from the contact patch, reducing hydroplaning risk and improving wet-weather grip. The all-season compound provides reliable traction across dry, wet, and cooler weather conditions throughout the towing season.
