• [Principle] The tire changer operates using air pressure, connected from an air compressor to the machine's air intake. When you step on the footswitch, the cylinder extends and retracts. As the cylinder retracts, it pulls the lever arm, which pushes the fixed hub assembly to rotate, making it easier to install and remove tires.
• [Portable Design] Measuring just 26.77 x 15.35 x 19.69 inches and weighing only 84.66 lbs, this portable tire changer is incredibly easy to transport. It fits in most car trunks, making it a good choice for road rescue and mobile car repair.
• [Tire-Friendly Features] Designed to run on air rather than electricity, this machine boasts a large cylinder for greater tire-changing power. Its duck head is specifically crafted to avoid damaging your tires during the process.
• [Application] The pneumatic tire changer is used for mounting and demounting tires from the rims, suitable for 12-21inch auto tires. Suitable for automotive repair shop, tire shop, or roadside assistance.
• [Note] Before removing a tire, make sure to loosen the bolts first. Then, use the tire changer to detach the tire from the rim. For installation, simply place the tire onto the rim before tightening the bolts.
