Yes.
I've had one blow-out with a Goodyear that still had 60% tread. Was just about 100 degrees and I was speeding (more heat). Uncommon temps for us, so I can totally get on board with the South Guys being a bit more concerned than us North Folk.

I'm sure they have blow-outs in the North Pole too, the point I was trying to make is that heat multiplies the chances.
I'd wager cold has a similar effect. Tires rolling in the sub freezing temps, not flexing like they would at 70*-90* or so, cracking when they would normally flex. I drove a lot in the freezing ass cold, when tires would go thump thump thump until they got some heat in them. Plastics that are flexible in the heat can and do splinter in the cold.
