Bloodhound SSC is designed to go 1,100 MPH on the salt. At those speeds, just the friction of the air passing over the aluminum wheels can heat them up to 200 degrees Fahrenheit. At 300 F, they could disintegrate.

Clearly, that's a bad thing. To figure out if the Bloodhound SSC's wheels could take the punishment, they borrowed a Rolls-Royce jet engine turbine testing facility. This is what they found out.
