The mass of a tire designed for heavy-duty vehicles depends on several factors, including its size, intended application (e.g., long-haul, off-road, regional), and construction materials. A typical tire used on a semi-truck can range from 100 to 200 pounds, while super singles or larger off-road tires can weigh significantly more. This weight contributes substantially to the overall vehicle weight, impacting fuel efficiency and handling.
Understanding tire mass is crucial for several reasons. Accurate weight calculations are essential for complying with legal weight limits, ensuring optimal vehicle performance, and calculating fuel consumption. Historically, tire technology has evolved to balance durability, performance, and weight. Advances in materials science and manufacturing processes have led to lighter, yet stronger tires, contributing to greater fuel efficiency and reduced emissions.
