Not that it makes a difference to what you're saying. Although tire blow-off is not uncommon for decenders who brake a lot, especially tandem teams, but the temperatures involved there are a lot higher than hot asphalt.
Yeah, I realize that, and figured someone would point that out, but you're still talking a less than a 10 psi change if the internal temperature of the tire went up 30 degrees coming out of the garage.
