Closed-circuit television footage from a security camera mounted in the lot of a Volkswagen dealership filmed the unfortunate result of a poorly maintained eighteen wheeler with improperly greased bearings. First seen in the distance hurtling off the expressway, the enormous, smoking tire bounced through the dealership parking lot before slamming into a parked car.

Seen later off camera: two understandably startled salesman discreetly changing their undergarments.
