Power King Boat Trailer II ST Bias Ply Trailer Tire

The Power King Boat Trailer II is an economical, highway-rated ST (Special Trailer) bias ply tire purpose-built for boat trailers and light-duty marine towing applications. Engineered around the real-world demands of seasonal boat trailer ownership, this tire line delivers dependable load-carrying durability, consistent highway tracking, and the sidewall strength needed to handle the unique challenges of launch ramp and marina environments.

Key Features:

• Bias ply construction provides a stiffer, thicker sidewall that resists road hazards, curbing impacts, and the abrasive surfaces common at boat ramps and marinas
• Strengthened internal structure with a special rubber compound maintains ideal tire shape under load and driving pressure, resisting deformation for improved load capacity and handling
• Circumferential ribbed tread pattern promotes stable straight-line tracking and reliable highway performance — the most common trailer hauling surface
• Deep circumferential tread grooves channel water away from the contact patch to help reduce hydroplaning risk on wet roads
• Tubeless design eliminates the need for inner tubes, reducing maintenance requirements and simplifying roadside service
• All-season compound keeps the rubber flexible across a range of temperatures, supporting performance in dry, wet, and varied seasonal conditions
• Weather crack resistance helps the tire endure extended off-season storage periods — a real-world challenge unique to seasonal boat trailer ownership
• ST-rated exclusively for trailer service; not intended for use on passenger vehicles or light trucks
• Available in multiple sizes and load ranges to accommodate a wide variety of boat trailer configurations

Power King trailer tires are designed with the boat owner in mind. The inherent sidewall rigidity of the bias ply casing guards against the impacts and abrasions typical of launch ramps and uneven marina surfaces, while the all-season tread compound supports reliable performance after weeks or months of off-season storage. The Boat Trailer II line offers the load confidence and value-driven reliability that boaters depend on for safe, worry-free towing season after season.
