Oh, believe me, it isn't too difficult. Ripping a tire to pieces can be
as simple as getting a puncture and not not stopping! The carcass simply
overheats and delaminates. The results are pretty hardcore lookin' and
often lead to sheetmetal damage, too, as the rubber flails around. Then,
with nothing left on the rim, all you need to do is slam a rock hard
enough and the wheel goes away.

Street wheels are designed to bend and dent, but are inherently less
rigid, therefore. Race wheel metallurgy, on the other hand, produces
very stiff and strong castings that tend to hold together better until
they reach their design limits. At that point, they may fail
catastrophically. I was experimenting at that rally between strength and
lightness (race rim) versus long-term durability with my usual street
rims. For rallying at my previous budget level, street rims proved to be
more practical.

the wheel. All that was left was the hub which was still bolted to the
disk. We were left with no wheel drive at all. So... to get around that
little challenge, I simply kept my foot on the brake pedal to add some
load. That produced enough resistance for the Quaife to work which got
us 13 miles back to service. -gotta press on regardless!
