Double tape over weld or over valve hole?

Valve stem IMO, because it lets you run the tape looser at the valve stem, which is what you want, to ensure it's up against the rim. When you stretch the tape, it is often lifted off the middle or comes off of it easy, great for the sides, but not so great for the valve.

Stan's says to overlap at the seam and other manufacturers say to overlap at the valve hole. I've done bunches both ways and have concluded that it just don't matter.

seems to me that even though both spots hold the potential for leaks, that overlapping at the valve hole probably is a better idea since that's the spot you're making a hole in the tape and shoving the valve through. a little extra reinforcement might be a good idea there.

for a crappy rim, that calculus might change, with the seam being more likely to have a problem. but on a quality rim where you can hardly see the seam? ehh, don't see the point of overlapping there vs. any other random spot on the rim.

I've taped up three or four sets of Wheels over the past 3 years. I can't even remember which way I did it. That's how important I think it is. Anyhow if I was doing it again right this moment I think I would cover the valve hole twice. Just seems more intuitive to me when laying it down.

Undecided flip-floppers can double tape the whole rim.

Double everywhere, triple over hole

Double over at the valve stem, that valve hole is a vulnerable area for leaks 👍. The weld/seam gets it's own piece of tape placed perpendicular to the rim (edge to edge). My last wheelset had Alex Rims DP30 on there and they leaked out the seam. I believe they were pinned instead of welded. Fixed it by running tape perpendicular across the seam, and it required going rim bead lip to rim bead lip, cutting off the excess.

Double is for amateurs.
