  0.75mm wheel skin thickness? check. Machined out of aluminum? check. Punctures and tears in the wheel? check. Surprised it lasted this long. I understand weight was a concern, but surely for $2B, there's some exotic, more resilient alloy that could've been used? Or maybe just make those middle wheels 1mm thicker and eat the extra 3 1/3Kg.
