The bead hold-down chain represents a highly effective solution for the demanding fitting and removal of UHP and run-flat tyres. By positioning the hold-downs precisely between the rim flange and the tyre bead, the tyre is reliably held at four points in the rim well during the rotation process. This effectively prevents the second tyre bead from riding up and reduces material stress on the tyre and rim to a minimum. The step-by-step placement of the chain links ensures continuous relief of the bead area, achieving a remarkably comfortable, controlled and process-reliable workflow in professional tyre service.
