Here is another small trick that came in handy to me yesterday:
Always install your tires with a feature you can easily spot (a label on the sidewall) aligned with the tube's valve.
Whenever you have a flat, just locate the puncture on the tube and you will have an instant reference of where exactly to look for the culprit stuck in the tire. Does this make sense? It will save you some minutes when repairing flats
This deserves a bump. Stunning in it's simplicity, I never thought of it. Prolly shouldn't have admitted that...
