A tire changer is a machine used in automotive service to remove and install tires on vehicles. It simplifies the process of changing tires by using mechanical arms and tools to grip, lift, and manipulate the tire and wheel assembly. This equipment is essential for tire shops and garages, as it speeds up the tire-changing process and reduces the physical effort required by technicians. Modern tire changers often come with advanced features, such as automatic bead breakers and digital controls, making them user-friendly and efficient. They are designed to accommodate various tire sizes and types, including those found on cars, trucks, and even motorcycles. Proper use of a tire changer ensures that tires are mounted safely and correctly, which is crucial for vehicle performance and safety.
