To add to Plastic bugs claims...
The thermal fuses in my companies fleet of A330 is set to melt when the hottest part of the rim reaches 205 Deg C as stated by the manual.....
I am not sure what plastic thinks aircraft wheels and tyres are made of to think they can stand 800 Deg C
Most ally alloys will deform at that temp and I am sure the tyres would burn.
And I have no idea what kind bearing grease to use in such high temperature applications.
