Puncture

[Austin Carr]

Tyres running at low pressure generate more heat. Excess heat causes the tyre structure to degrade. Eventually the thing explodes, or at very least sheds its tread.  This is what has happened to the bits of tyre you see lying on motorways. So, the main danger these days is not being stranded at the side of the road with a flat tyre, but being stranded by the road with a flat tyre a couple of weeks later because you didn’t check tyre pressures.  Of course all of this is irrelevant because all of us here check our pressures every week, don’t we?

I haven't noticed so much tyre debris in recent years and have always believed that the improvement in remoulds was the reason.
