Some may jump on me for speculating.
Perhaps someone, somewhere is supplying "scrapyard" components from old airframes, which then fail?
Or it could be an engineering problem - perhaps the tyre pressure gauge they use is faulty and the tyres are being under-inflated, causing overheating and failure. Or they are setting the wrong pressure for other reasons.
The first two incidents could have been caused by under-inflated tyres. The last one suggests a braking problem to me, so probably unrelated - unless the treads of all four tyres were worn below the limits?
