[Land-speed] Tire Diameter

[Elon]

I don't understand, JD? If the tire is NOT speed-rated for 200+ mph how can
you pass tech? Rules require a 200mph tire to run on records over 200mph,
no?  -Elon

)Snip . . .) I do not think they are given a speed. I believe a fuel
roadster has lost tread on a shaved 550-18 Dunlop, which is 30", right at
240 mph. I looked at mine after every run as every one should with their
tires of any kind. I don't believe anyone has spun them to destruction.
