Bush failure at 14k miles - causes?

[Fun Bus]

My GF's Father has a 2009/59 Cooper and has just had the bushes replaced at 14k miles. This seems unusual and he's interested to know what could have caused them to fail so soon?

He's also said the tyre pressures are at 55psi? Is this right on run-flats which I'm sure it has?

Any advice appreciated.

My thoughts too. I'm sure I've interpreted him correctly - I'll confirm though. If not the case are the bushes a known weakness on the Mini?
