reportp it doesn,t quite work like that ref the tyres. They are high pressure or low pressure tyres, size rating etc are different, and there are different specs for the wheel well area as a result of the size (lp being bigger). Why they "blew" on landing is anyones guess with the lack of info at this stage, however depending on landing weight the max tyre speed can be exceeded and that may well cause overheat or other damage. It,ll be interesting to see some more facts when they are revealed. Sounds like a good job done by the crew.
