What is a pinch flat and how can it be prevented while cycling?

A pinch flat, also known as a snakebite, is a type of flat tire caused by the inner tube being pinched between the rim and the tire when hitting a sharp object or a hard bump. To prevent pinch flats while cycling, you can:

1. Maintain proper tire pressure to avoid excessive compression of the tire against the rim.
2. Avoid hitting potholes or sharp objects at high speeds.
3. Install wider tires or use tubeless tires for better impact absorption.
4. Use proper technique when riding over obstacles, such as lifting your weight off the saddle.
