"Supposedly" once you get the Ride-on to go into and through the hole, it should hold rather permanently. I've got a rather new Avon front that had/has a tiny leak from a staple, or something very small. I couldn't get Ride-On to seal, but wrote them, and got directions. They said sometimes, it's necessary to make the hole larger, so that the Ride-on can get in there. I will experiment at a later date. Replaced front wheel with another I had, that has a brand new Metzler on it. (I know, I know) but it was easy.
