Well, mine wouldn't hold air with one loop! If you're the gambling sort leave them overnight and see if they hold... if it's one loop of good tape, well taped and rim/tyre combo is a good one maybe it'll be fine?! If you'd rather play it safe then all off, clean and dry everything, new tape job with two loops.
