I checked both sides of the rim, and the little line is exactly the same all around, on both sides.
I just didn’t hear the pop people talked about.
The rim is new, the tired is original to the bike.
Schwalbe Nobby Nic 2.6 29”.
Also, I installed Stan’s tire sealant (160ml)
And I pump to the max of the tire which is 45Psi.
I did it differently than every video I saw, I went slow and steady with a regular stand bike pump.
Thank you.
