You thinking I should finish at the valve?
I'm saying that it is not coincidental that the failure occurred near where you start or end the tyre mounting. Try this slight modification to procedure:
1. do not install tube flat, pump in some air so that it is round in shape before inserting into wheel & tyre
2. mount tyre as usual
3. after tyre-mounted, push valve-stem into hole, so that it contacts tyre on opposite side internally
4. next, push edge of tyre sideways and look into gap between rim-edge and tyre. Move over 6-inches and push tyre aside and look at gap again, repeat 6-inches over. No tube should be visible all 360-degrees around wheel. Repeat for other side of tyre.
5. pump up to operating pressure.
6. install valve-stem nut if you wish, I prefer to leave them off.
