This is one of those things that seems common once you see it. I spent a couple years living in Prescott National Forest in northern Arizona, and split wood to warm my house. It didn't take long for a neighbor to come over and suggest a tire after watching me chase down all the wood I flung in every direction.

It seems this leveraged action (which is absolutely awesome, by the by) would necessitate the use of a tire even more. Beware of windows, cars, etc. without one.
