I have an old tire that has one lump in the sidewall. It's an old skinwall, and the threads are starting to deteriorate. Obviously it's a goner, but until my new tire arrives is there any way I can patch it and keep riding? It's just the back tire on my cyclocross bike, so I won't be stranded if it blows out. It's still holding air at the moment but probably won't last much longer.
My idea was to cut up an old tire and put a piece between the tire and tube to give it some shape.
