"These things are a life saver, or more accurately, a bike-saver! We used them as a back-up, strapping our road bike wheels to our hitch-mount tray-style bike rack for a long 1,000 mile road trip through Appalachia. On the ride home, through loads of bumpy highway construction, one of the clamps holding the bikes to the hitch loosened and the bike bounced it's way off the rails. These straps held to the wheels and kept the bike attached to the hitch and attached to the truck. We were flagged down by another motorist letting us know we were dragging a bike, and thanks to these straps were able to save a very valuable bike that would've been toast, and could've caused a serious accident. Sure, there was some subtle damage to the wheels, dragged as they were, but these things seriously earned their keep."
