Puncturing Pneumatic Tires

[Ryan Dognaux]

We managed to get a rivet mandrel impaled all the way through the tire and intertube. It was funny seeing a small metal dot and then pulling out a long rod. On the plus side, it's made us have spare parts ready to go to easily swap wheels.

Watch your tire pressures. Too low, and when you hit the rock wall the tire (and tube) will fold and compress against the wheel edges. The result will often be 1 to 4 holes in the tube. These pinch flats are well known to offroad bicyclists and motorcyclists.
