What to look for in a new tire changer?(2)

Today I continue to tell you about looking for a new tire changer tool.

Higher Voltage Equals Higher Torque

Servicing of heavy wall truck tires or wheels and tires with stubborn performances can cause the turntable on a tire changer to stall. A machine operating on 220V has a better chance of restarting and continuing after a stall. That makes the 220V machines more important, especially as new light duty vehicles now increasingly come with aluminum rims, TPMS sensors and most of them are of the run-flat variety of tires.

Most often, a tire changer needs a separate assist arm put up on the far side of the tire. A tire bar is then required to depress the bead in between the rim and the mounting head. The tire bar has to be readjusted by repeating the process when the user turns the tire by about 30-degrees or so.

While installing the tire, the turntable might stop turning as soon as the technician lifts his foot off the pedal. This may happen even if the rim has been secured properly and the bead has plenty of lubrication on it. Sometimes, the technician may need to take his foot off the pedal, as the tension from the bead can pull the mount head into the rim, causing damage. The technician may also need to stop for adjusting the tire bar to avoid tearing the bead.

Since the turntable needs to keep moving to prevent damage to the rim even as the bead gets tighter a 220V machine with proper assist arms is preferred. The technician can make adjustments freely knowing that the turntable will readily rotate afterwards. A struggling turntable may need another technician to help spin the tire, and a 220V machine makes the process safer and more efficient.

Future Requirements

Vehicle users desire large rims and fuel economy requirements need tires with low profiles. Both these requirements are affecting the type of tires that fleets now have to work with. Therefore, it is preferable to have a tire changer with a large turntable along with a tilt-back mechanism. This will allow accommodating not only the tires already in the marketplace, but also adaptable to the future thinner tires with larger rims.
