Indeed; tyre maximum speed rating is based on thermal limits; if the
heat from flexing of the steel and rubber can't be released quickly
enough, the tyre separates from the wheel.

Reminds me a few years ago we stopped to rescue a 20-something
military male with two rear wheels blown at once, and no spares.  On a
120 km (75 mile) sealed highway with 110 kph (70 mph) speed limit,
just after a long sweeping bend.

He said the ride got really rough really quick, he was thrown forward
into seat belt, then he saw his tyres departing from the road in front
of him.

We got him radio coverage for long enough to call for road service.

He was driving from Adelaide to Brisbane, via Broken Hill, without any
stops planned.  2038km (1274 miles).
