Someone school me please. I go through dry spells before I get flats but when I do it always comes in 4's or so and literally one after another.

like today I had one on the road, replaced it with a patched tube got to work and it goes flat but this one was easy valve stem was engraved into the wheel.

Replaced it with a bell flat resistant tube, couple hours later flat due to a tear near one of the seams where the tube would touch the rim tape, nothing protruding nor any objects/fragments found. Replaced that one with another fresh one after checking the tire/rim and giving it a scrub, flat again within hours. Maybe Im mounting them wrong somehow or they are getting pinch someway?

- once Im ready to put the tube back in I inflate until its a little round. Stem goes in first following the rest of the tube clockwise with my hands.
- I then rock the tire back and fourth with my hands to sit the tube, I even deflate completely, and inflate to about 7 psi and do the same thing.
- Once all in I inflate all the way.

When I get flats, I never seem to have a puncture, its always tears. Help me please.
