not tightening allows movement against the rim and it can damage it, cause it to lever the stem and break it, etc. If your tire is going to move.. rim-locks (thats kinda why they exist) or screws thru the rim to the tire bead. THATS the correct way. But do whatever you want. if it works for you leaving them off... sweet. We all have preferences.

However, If they weren't meant to be tightened they wouldn't waste money cutting threads on the valve stems & include the nuts. They would leave them out and charge more for less and call it a specialty tube. ;)

Googling seems to show it as controversial as what oil should I use. I’m on team don’t tighten, the downside to tightening it is it can rip the Stem off the tube, the picture posted seems to show exactly that…

I did read just today rim lock tighten against the rim, no rim lock then against the valve cap. My 10’s of thousands of Baja miles when I ran tubes say do not tighten against the rim. Ymmv
Good advice, allowing the tube to slip a little might prevent the valve stem from ripping out!

One of the pluses of the “ghetto” tubeless conversion is that the remaining tube part is clamped between the wheel’s rim and the tyre’s bead - it cannot move so cannot have any hand in damaging the valve/tube interface
