These irons are designed for fast and efficient tire changing. Use the 18" and 24" spoons to mount or demount passenger car, motorcycle, ATV, and light truck tires. The 30" spoons provide enough strength and leverage to work on large truck, bus, off road vehicle, tractor and aircraft tires. Use in pairs.
Donut-style mounting rings are a simple, yet effective mounting device that over the rim between the bead and rim flange creating a seal. As the tire expands, the mounting ring slides out over the rim allowing the beads to fully seat.
