BEAD-UP INFLATION RING with Rubber (420610)

Description:
This particular Rigid pump ring is designed for 22.5″ rim dia truck tyres. The pump ring is seated over the rim such that it forms a wall around the rim.
It is used for deformed rims, hard-to-seat radial or bias-belted tyres.
As tyre is inflated, the Pump ring forms a seal between the rim and tire (cancelling air leakage), allowing the air pressure to force the tyre bead into the rim flange.
As the tyre is fully inflated, the pump ring slides out over the rim.
Made from high quality metal.
Comes with a rubber ring inside to give friction while the pump ring comes out and also saves the rims from damage.
The inside rubber ring can be replaced.
