I'm fairly sure the Stinger's low pressure alert is somewhere in the high 20s, as I've seen it triggered when I've gone up in elevation locally in colder times of the year. But the overarching point that something could have been awry (blown belt even) or stuck in the tire leading to the failure is valid. I'd think at 160mph the driver would have experience severe shuddering much sooner and at lower speeds prior to failure. The fact it was fine then not indicates to me a unpreventable catastrophic failure.The tire pressure could have been high enough to not trigger the low pressure alert. On my Corvettes the low pressure alert comes on at 24 psi. Running at 160 mph would require tire pressures to be near the high end of the operating range to avoid overheating the tires. The other thing is that the tire may have been punctured while driving at that speed causing a loss of pressure resulting in the tire coming apart.
There's roads out here in the West where many miles of clear line of sight and quality pavement can afford one some relatively safe 'stretching of the legs'. I'm not sure I'd ever have the nerves to hit 160mph in a street car without at least roll cage/helmet, and maybe a spotter way ahead.
