Bringing a tire to outer space, with no external pressure on it any more, just brings the effective pressure in the tire up by 14.7 psi.

Leave out the valve stem. Same PSI in as out and the tire will hold it's shape due to the structural rigidity of the tread and sidewalls.

That was among the 4 or 5 low-tech solutions that immediately suggested themselves to me. If it was a problem to begin with. But no, the people that successfully launched a massive rocket, and brought about the simultaneous landing of two rocket boosters could never be as smart as us, right?  ;)

With that one statement, you've captured the mindset at APS.

Salon being Salon again:

https://twitchy.com/brettt-3136/2018/02/13/salon-elon-musks-launching-of-a-tesla-was-a-slap-in-the-face-to-real-science/

Because everyone wants to spend a year and $$$ to develop a science suite (plus setup the infrastructure to monitor the sensors for the next "X" years) to stick on top of the first launch of an experimental booster. Salon evidently never watched The Right Stuff (probably because it was the patriarchy).

"Real science"? Was Musk claiming to do science, or was he doing technology? I honestly don't know what his pretensions were.

Salon should probably at least google things before typing.

Test launches of new rocket designs NEVER have real payloads.  Because test launches of new rocket designs blow up a lot, and who wants to blow up their fancy satellite/test instruments or whatever?  IIRC the Falcon test launch had a huge wheel of cheese.

The real gripe there is they don't like Musk, so nothing he does is allowed to be OK.

At one point there was a really good Aardman Studios documentary on Netflix. No idea if it's still available.

One of the comments on the video said it must be fake, because obviously the tires would explode in space, right? Then somebody replied that, duh, it's not some regular car - it's made for a space environment, dummy. :laugh:

The tires would not explode unless they were over-inflated to begin with.  (pretty sure the correct inflation for space would be about 15 psi less than on Earth)

In other words -- roughly zero psi. (Atmospheric pressure at sea level is approximately 14.7 psi)

No, it would be normal tire pressure (30 psid) reduced by 15 psid before launch so that the final pressure once in space would be back to 30 psid.

Y'know, if I had Musk's bank balance, I'd have very secretly put some serious animatronics in that suit, on a long delay timer.  Wait until the people who were watching it live from launch got bored, then have it wash the windshield, lean the seat back, scratch, etc.  Start the rumor that this is the most epic assisted suicide in history.
