Matt of Bike Hikes has an interesting idea. He's put old seat belts inside the tires of his bicycle to make them more resistant to punctures:

The idea is very simple - put something between the tire and the inner tube to stop glass and other objects. So I found some old car seat belts left from a pair of messenger bags I made and I used them like a anti puncture band.

Do you think that it will work?
