My sympathies. We've had the hottest July ever in the California Central Valley (hit 111 at the house) and there are times my ebike can't recharge until it cools off after an afternoon ride. Too hot.

I have retrieved a bike from my car trunk to find the tires blown off the rims. This was pre hook-bead rim days and I have not had that experience since on modern rims, but still think it's possible. My bike locker at the office is in the sun all day and mid-summer I won't take chance on leaving a bike in it during a heat spell. Guessing it gets to 150 or more inside, on a triple-digit day.

PITA but stowing your bike with the tires partly deflated seems prudent, Just pump them to spec when riding, then release some air when stowing. PITA but much less than replacing a tube.

Wonder if tubeless goo cooks and loses moisture when stowed hot?
