Gary:
probably centrifugal growth is the biggest factor for lsr tires, as
suggested.
However-- tire heating may sometimes be a significant problem, too. A
free-spinning tire doesn't produce significant heat, so that factor isn't
tested in such a rig.
The heavy carcasses of the av tires surely shrug-off the static and impact
mechanical loads that we lsr folks put on them-- but I doubt that that is
the case for the thin-wall tires designed for landspeed racing. And some
years Bonneville can be fairly bumpy. And many lsr vehicles are "rigid"
suspension.
Still-- I don't mean to belittle the value of the data; resistance to
failures due to growth is probably the most important thing we could
measure.
