Hmmm, can't help with the conundrum and who cares if it is
misleading, a lot of ads are. You ever bought a hamburger that looks
like the ones in the ad?

30,000# is only 7500# per wheel and a tire would probably managed to
cope with that momentary load without bursting. Might rip some cords
but hitting a deep pot hole at speed can momentary load up a tire as
much or more than that.

I know that an object gains energy as it falls.

"Gains energy," really? I suspect you mean the energy is converted
from Potential to Kinetic! {grin}
