I hang mine over the tire and forget about it, haven't lost one in eight years. Wind blows them off on occassion, but rarely. I just got tired of getting on my knees etc, do now I don't.
Also by way of disclosure I cover the entire RV during storage so if I use tire covers then they are also held in place by the overall cover. But I leave them off now because the full cover takes care of them.
But if I were to do it over the snap ring idea is a winner with me. But my covers are in great shape.
I do all my own stunts
