But, when I went to an aviation museum there was a nose gear from some sort of airliner... The guide explained that it was not completely burning rubber but gas and that the tyres need to be re-inflated before TO. Just cant remember what the gas was. I'm guessing a hard landing would increase the pressure it the tyres a fair bit so possibly there is some release valve?
I'd hope that the gas isn't burning, it's nitrogen.
If I could make that bloody thing react I'd be a millionaire !!!
