BF Goodrich dropped a set of their new KO2 off-road tires out of an airplane flying at 10,000 feet, rounded 'em up, slapped them on a Jeep Wrangler, and drove off. Even if that test isn't particularly relevant to a tire's primary function (providing traction) it's a damn impressive display of durability.
I drove the KO2s on Ford Raptors and open-wheel buggies in Baja, Mexico last month, crashed into just about everything, and wasn't able to tear a hole in them either.
This clip is a pretty solid testament to the strength of the rubber (and Chrysler's OEM Jeep wheel). The only problem of course is that we've never seen any other tires go skydiving. Maybe a used set of Tiger Paws would survive just the same. But I doubt it, and even if they would I don't really care because this is a lot of fun to watch.
Here's a little behind the scenes to check out how the put this together... and kept track of the raining wheels.
