Stan's NoTubes ZTR rims feature next-generation BST (Bead Socket Technology). BST is a proprietary, patented design feature which incorporates an inner curve that is the same size and shape as the tire bead to create a tighter tubeless seal and reduce strain on the tire bead. With short sidewalls, the tire should not hit the rim and pinch flat as often as when tubes are used. This design allows you to run lower pressures and use 4mm more of the tire than ever before.
