Gravity's the biggest reason this doesn't work; there's probably some bounce directed onto a small area on the surface of the pipe, but the rest of the thing is still affected by the potential energy and is going to essentially sheer off (I'm simplifying things, but that's, TMK, the gist of it).

As to what would work better... a crane? A ramp? One of them hydraulic lifts you see at the back of some trucks? There are many options to consider before "throwing it off the end and hoping for the best."

Concrete has interesting properties

Concrete (that is not reinforced) has insanely high compressive strength, but is very brittle and has zero tensile strength. You can squeeze it all day long and do almost no damage, but the second it takes a sudden jolt or is stretched, it breaks. ...

Concrete (that is not reinforced) has insanely high compressive strength, but is very brittle and has zero tensile strength. You can squeeze it all day long and do almost no damage, but the second it takes a sudden jolt or is stretched, it breaks. When it connects with the tire, the material would try to deform to an oblong shape. However, that requires stretching the material, with the most force at 0, 90 180 and 270 degrees. As the concrete is not reinforced, and is forced to stretch, it breaks at those points until the tension is relieved. (Which is why it breaks into 3 pieces not four).
