Evening all from Estuary-Land. I've never had an actual blow out but I've had a few punctures in my time, the last was only a few weeks ago as I mentioned here on ER's. As far as I am concerned second hand or remoulds are a no-no, I always buy brand new. Many years ago there was a demonstration by the police of some of the horrors of second hand and remould tyres. One was a second hand tyre that had virtually disintegrated at speed throwing the car out of control, the reinforcing bands had split and taken the rest of the tyre with it. The remould had suddenly developed a massive blister on the corner of the tread and had flipped the car onto its roof, also at speed. The first tyre had been 'kerbed' breaking the steel reinforcing bands, the tyre fitter would have known that the tyre was dangerous as before it was fitted to the wheel the distortion would have been obvious. The remould was badly done, the original tyre was not prepared properly and the remould cover was not 'sealed' properly. A split in the original casing spread and burst but the air stayed within the remould casing instantly making the tyre 'balloon'. This was 40 years ago before the consumer protection acts and of course remould tyres are now vastly improved but I still replace with new tyres.
