If you're not afraid of being clipped by a runaway tire...you probably should be.

Thanks to the Twitter account Catastrophic Failure, we now realize that the odds of being clobbered by a stray tire are far more likely than we had originally thought. Lest we forget that the collateral damage is typically critical in these situations.

We've collected some of the gnarliest videos of unsuspecting pedestrians getting absolutely wrecked by loose tires. If nothing else, we just hope this piece makes you a bit more aware of all the danger that lurks around every corner. Especially when it comes to tires. Head on a swivel out there.
