>>1474471When you get a flat, even if you don't patch your tubes because you like wasting money and resources, pump the flat tube up and trace the flat there.
Eventually with enough pressure you'll always be able to hear/feel the hole.
Then you know whether it's
>a puncture on the inside of the tube caused by the rim/spokes/tape>a puncture on the outside of the tube caused by debris>a snakebite caused by an impact/ too low pressure pinch flatting Then you find the exact corresponding place on the wheel/tyre and investigate it there. So you have to keep the tyre in the same place on the wheel, and keep the tube oriented the same way too.
If you don't follow this routine you'll miss things and be struck by the same flat multiple times.
