If it is a UST rim, isn't the rim bed free of holes? A feature of UST is that it is supposed to be able to seal without tape. If this is not the case, depending on the tape used, one turn with about 4-6" overlap should suffice. To account for the channel in the center of the rim bed, your tape needs to be 2-3mm wider than the internal width, in order to ensure the tape is wide enough to touch both sides of the rim while also conforming the contours of the center channel.
