"Donut-Style" Mounting Ring 20"-21"
Donut-Style Mounting Ring 20" - 21"
This mounting device fits over the rim between the bead and the rim flange creating a seal. As the tire expands, the mounting ring slides out over the rim allowing the beads to fully seat.
NOTE: O.S.H.A regulations require that service personnel use a clip-on air chuck with an inline inflater at a recommended distance that keeps the employee out of the trajectory of the tire and rim. After beads are seated, put tire and rim into approved inflation cage and continue to inflate to prescribed pressure.
