I'm converting this old clincher rim to tubeless as part of an upgrade project for my old MTB. It's sleeved, so I assume there's a 99.99% chance it will leak at the seam. After reading so many threads, I'm now even more confused about the definition of "wall to wall." Which method is correct? One or two layers?
A. Bottom only. Let the sealant do the job. Tape width will be about 23 mm.
B. 1 mm up the sidewall. Not sure if this will prevent seam leakage. Tape width will be about 25 mm.
C. Hook to hook (source: https://www.mtbr.com/threads/tubeless-with-a-sleeved-pinned-joint-sunringle-helix-tr-rims.950170/). Tape width will be about 27mm.
I really appreciate any insights based on your experience converting old clincher rims.

5mm + inner rim width is always a safe bet. If you’re worried about leaking at the seam, take a qtip and wipe the seam with sealant before installing the tire. I also always recommend dipping the tubeless valve grommet in sealant as well to prevent leaks at the rim.
