Maybe if I were using Gorilla Tape I would be less worried about this since the adhesive is much stronger. Also, if you ever need to unseat the tire, I would be concerned that the bead would scrape across the edge of a narrow tape (especially if you have a double layer), pulling it up. If the tape is edge-to-edge, then the bead is already in contact with the tape, so when it pulls away from the hook it should just slide over the tape with minimal damage. On the other hand, wider tape is easier to mangle with a tire lever so it's tricky either way.
