What are the best techniques for using tyre levers on a bike to efficiently change a flat tyre?

To efficiently change a flat tire on a bike using tire levers, follow these steps:

1. Remove the wheel from the bike.
2. Insert one tire lever between the tire and the rim, then slide it around the edge to loosen the tire.
3. Insert a second lever a few inches away and repeat the process.
4. Once the tire is loose, use the levers to carefully pry the tire off the rim.
5. Replace the inner tube, then use the levers to carefully re-seat the tire onto the rim.
6. Inflate the tire and reattach the wheel to the bike.
