In these machines, the tire is inflated using high volume, high pressure compressed air that flows into the tire around the tire bead rather than through the valve stem. Depending on the tire size, machines may be a single station or multistation. Higher volume producers typically utilize specialized tire and wheel mounting and inflation equipment which is partially or fully automated. Semi Automatic and Automatic mounting and inflation machines However, now, bigger versions of the heavy-duty tire changers are designed to mount/demount tires up to 95 inches (2.4 m) in diameter and also feature a hydraulically operated self-centering four-jaw chuck with clamping jaws that can clamp from 14 to 58 inches (0.36 to 1.47 m) either from the wheel’s inside or from the center bore. Heavy-duty tire changers are used for agricultural, off-road and construction vehicles. Heavy-duty tire changers can work with some wheels up to 56 inches (1.4 m) in diameter and tires up to 90.5 inches (2.30 m) in diameter and 43 inches (1.1 m) wide. Heavy-duty tire changers require larger equipment because these changers deal with larger, heavier tires and wheels. In addition, small atv wheels and tires are used on motorcycle tire changers. Certain motorcycle tire changers can accommodate wheel diameters as small as 10 inches (250 mm) and wheels at least 1 + 1⁄ 2 inches (38 mm) wide. Motorcycle tire changers mainly provide a simple bead loosening system and rim clamps powered manually.

Motorcycle tire changers are less sophisticated than passenger car and light truck or heavy-duty tire changers because they deal with smaller and lighter tires and wheels.

The operator releases the rim clamps and inflates the tire to manufacturer specifications.The operator slowly inflates the tire until the beads "pop" on the bead ledge of the wheel.The operator pushes the top bead down into the center well of the wheel under the duckhead and rotates the table top using the table top pedal.The operator pushes the bottom bead first in the well of the wheel.The operator centers the wheel and securely fastens it onto the table top with the rim clamp mechanism with the narrow bead-ledge up of the wheel.The following list provides an explanation of an operator installing a tire onto a wheel using a tire changer.
#TIRE CHANGER MACHINE MANUAL#
The manual bleed valve allows the manual release of air pressure from tire. The manual bleed valve is located next to the air hose and air inflation gauge. When the inflation pedal is raised, a burst of air is released from valves next to each rim clamp toward the bottom bead of the tire to help with inflation.

Directly below the air hose on the side of the tire changer is the inflation pedal that enables the inflation of the tire. The air inflation gauge displays the pressure in pounds per square inch (psi). The air inflation gauge displays the air pressure within the tire when the air hose is connected to the valve stem.

A specialized end is used on the air hose to clamp firmly onto valve stems of the wheels. The air hose is located near the top of the tire changer, and it allows compressed air to travel into the tire. The air pressure system consists of 4 components: air hose, air inflation gauge, inflation pedal and manual pressure bleed valve. The air pressure system on a tire changer provides the air to inflate tires mounted on wheels. Valve system including air inflation gauge, air hose, and air pressure bleed valve
