What happened with the previous Velox tape was that the edge of the tape rode up slightly on the reinforcement channels and, when inflated and ridden, curled over and eventually slipped into the center of the bed. It barely exposed the spoke hole, but I didn't want to take chances. I can try cleaning the rim again, in case that was the issue, and also buying another 16mm Velox strip.
