Many blowout incidents are probably 'heat related', but not in the way most people think about it. Heat does cause the pressure in the tube/tire to go up, but as has been pointed out, not to a point where the pressure itself will cause the tire to fail, but to a point where a previously unknown problem (pinched tube, tiny cut in tire, bad rim tape, burr/sharp edge on spoke hole, weak area around valve) causes the tube to blow.

A lot of heat related blow outs are due to braking hard on a descent and ripping a hole near the valve stem. Also the tube can stick to the tire if you don't use baby powder and this can lead to blowouts in these situations.
You would have to get the braking surface amazingly hot to heat the air in the tube very much. A lot of cooling due to air flow and the rubber is a pretty good insulator.

Strictly related to Forumula 1: I suspect that the suspension issue is
related to control, not rolling resistance. The former will help F1
speed much more than the latter.

Not following you here. How is this heat-related? Are you saying that
it is due to movement of tube and tire relative to rim?

Yes, this can happen with both tubulers and clinchers. Especially with tubulars the heat help melt the glue and the tire moves.
