      I'm pretty sure that rocket science is only as good as the scientist's mustache... I think that's the Bernoulli Principle... don't quote me on that.

      As far as tires....Thrust SSC had solid aluminum wheels....I am assuming Bloodhound will do the same...
      Meaning just metal, no rubber at all? Interesting.

      Yup. You gotta realize the wheels are subjected to a huge amount of centrifugal force and friction. Think about the rotational speed of the wheels at 1000mph. No tire on Earth could handle that. A solid chuck of metal is the only thing that can withstand those forces and not melt due to heat generated from the frictional forces.

      Yeah I mean I kind of figured it wouldn't be rubber, but thought maybe there was another material covering the metal they'd use instead(dunno, kevlar or something??) Interesting though, thanks

      Isn't aluminum very malleable though? I suppose at the salt flats it wouldn't be an issue since there's not much risk of running over anything. I wonder how it behaves at those speeds/temperatures.

      Probably something like billet titanium wheels; no rubber involved.

      ...2000! Ya, sure Waldo.
      Yeah I'm not sure he understands how this works. Based on this table of the X-15's fastest flights it appears they were all set at 100,000 feet or so. The atmosphere is about 1% as dense at that altitude as it is at sea level. Granted, the salt flats are going to have something like 87% of sea level density due to the elevation there but that's still 87 times as much air mass to punch through the X-15 had to deal with on its record setting flights.

      We're actually getting pretty close to the land speed records closing in on the maximum low-altitude flight record, set by a privately owned F-104 Starfighter at 988mph in October of 1977. If these 1000mph land records turn out then we'll have an odd situation where the fastest land vehicle is faster than the fastest aircraft ever flow at low altitude for an FAI record.

      Wheel specs are here: http://www.bloodhoundssc.com/project/car/wheels

      The high speed wheels will be forged from solid aluminium, using low-risk techniques and materials that have worked well in the past

      Each wheel weighs 95 kilogrammes, will spin at over 10 000 RPM and will be subject to a force of 50 000 ‘G’ at the wheel rim..

      The wheels are fairly straightforward ...but nothing is simple when you’re planning to do 1000 mph!

      No exotic alloy. Just billet aluminum, probably a very high grade type.

      More info about the wheels:

      Check out the different profiles they proposed to use. And the brake they plan to use is nuts.

      120mm aluminum wheel. "it'll be like driving a road car on ice" AT 1000mph!

      I would have thought aluminium to be too soft for such high speeds...

      I couldn't focus on the car due to the sheer lenght of the scientists moustache.
