RPT aircraft have been lost due to tyres overheating and catching fire in the wheel wells shortly after take off. A swiss air DC-9 crash in the sixties comes to mind. AFAIK, this has never happened with a N2 filled tyre. If the tyre is smouldering or whatever, and bursts, air will rush past it at high velocity, increasing the fire, whilst N2 will tend to put it out. Fusible pressure plugs are also used to safely vent tyres if overheating, usually incorporating an overpressure burst disc for overpressure protection as well.
