A tire changer is a machine used to remove and install tires on vehicles. It simplifies the process of changing tires by using mechanical arms to grip the tire and a rotating turntable to assist in the removal and installation. This equipment is commonly found in auto repair shops and tire service centers. Tire changers come in various types, including manual and automatic models. Automatic tire changers are more efficient and require less physical effort from the operator. Proper use of a tire changer can help ensure that tires are mounted correctly, promoting safety and performance on the road.
