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 clamps to hold the wheel securely while the tire is either taken off or put on. This equipment is essential for tire shops and garages, making tire changes faster and more efficient. Most tire changers are designed to work with various tire sizes and types, including those for cars, trucks, and motorcycles. They often come with additional features, such as built-in inflation systems and bead breakers, which help in preparing the tire for installation. Proper use of a tire changer can enhance safety and prolong the life of both tires and wheels.
