Centennial Hiway Master ST Bias is an economical all-season highway terrain replacement tire, manufactured for trailer, boat, camper, or snowmobile trailer. The solid ribbed tread design promotes better steering responsiveness, tracking and highway stability while driving. Solid shoulder ribs enhance the cornering and maneuvering capability and promote a comfortable and safe performing capability. Hiway Master ST's zigzag circumferential grooves prevent hydroplaning by evacuating the water and slush from the tire's footprint. With the exceptional towing, the reinforced bias ply technology helps to optimize the structure against the pressure affecting the tire while the trailer is being towed. That improves the load carrying and withstanding capability, and promotes a secure towing experience as the tire's shape does not deform under the towing and load pressure.
