The powered wheels of a tractor-trailer, responsible for propelling the vehicle forward, rely on specifically designed heavy-duty tires. These tires are engineered to handle immense weight, torque, and long-distance travel, featuring deep treads for traction and robust construction for durability.
These specialized tires are critical for safe and efficient over-the-road transportation. Their performance directly impacts fuel economy, braking distance, and overall vehicle control, contributing significantly to the profitability and safety of the trucking industry. Historically, advancements in tire technology, such as the development of radial ply construction and improved rubber compounds, have dramatically enhanced the performance and lifespan of these crucial components.
