In the tubular tyre-rim interface, the difficult surface to work with is the rim. Base tape, which is just about always a woven strip of cotton cloth, is easy. Glue seeps between the threads, stays there, and dries. The rim is another story. The glue has to bond to the rim in some way, but not permanently.
