Hot brakes, mostly when left in park post landing and taxi, can cause the wheel fusible plugs to melt (wheel hub at about 200*C) and tyres to deflate. I had one such incident, narrow body, in Riyadh, a replacement wheel had to be flown in. Also a wide body, with a full set of new brakes glowing after reaching the terminal, luckily the crew had released the park brake after chocks in and I had two air conditioning units on standby for the cabin and used these with great results.
