Which wheel is stronger, an aluminum wheel or a steel wheel? This video shows how a Chevrolet Venture five-spoke aluminum wheel, complete with tire, cracks into pieces under 20 tons of pressing force. In a way, the clip shows what a really, really big pot hole can do to both kinds of wheels: the alloy wheel cracks, and the steelie bends without cracking.
It's only when the pressmaster decides to place an aluminum wheel on its bottom when things start exploding: the tire blows off the rim in such a bombastic fashion that bits of aluminum get thrown everywhere. Good thing there's enough protection for the video crew. And as for the steelie: it just gives way, as a steelie does. The video serves as a good instructional clip about the wheel materials' different characteristics, worth keeping in mind if you live in Potholeville, USA.
