A typical tire used on a tractor-trailer combination vehicle can weigh between 100 and 150 pounds. This weight varies depending on the tire’s size, intended application (e.g., steering, drive, trailer), and construction. For example, a wide-base single tire often used on trailer axles can weigh significantly more than a standard dual tire assembly performing the same function. A complete set of tires for an 18-wheeler can collectively weigh over a ton.
Understanding tire weight is crucial for several reasons. It factors into the overall vehicle weight, influencing fuel efficiency and legal load limits. Tire weight also affects handling characteristics and braking performance. Historically, tire technology has evolved to balance durability, performance, and weight. Early tires were considerably heavier than modern versions, impacting vehicle operation significantly. Advancements in materials science and manufacturing processes have led to lighter yet stronger tires, contributing to improved vehicle efficiency and safety.
