Back to front...tyre question

[hubgearfreak]

tyres are only twenty quid, it's worth getting new ones just 'cos you don't like your old ones, or just 'cos you feel like it.

i agree

Buy a turbo trainer and a spare rear wheel - that'll then give you something to do with your old cast-off worn rear tyres

Apart from the "blow out" bit, as it's impossible to have one on a bike. They're called punctures!

Surely you can have a blow out on a bike - taking it to be defined as an uncontrolled rapid deflation.

A puncture with go down slower, usually letting you stop before anything nasty happens.

I did once have a tyre separate from it's bead - the resulting unplanned deflation (due to the tube squeezing out of the gap between tyre and rim) was explosive (a bit of tube hit me in the leg...)

All bicycle flats are just that - flats. A high pressure tyre might go with a bit of a pop, due to that high pressure, but it's still just a puncture.

A blow out by definition happens to a partially deflated tyre and is due to the friction caused by the sidewall of the tyre rubbing on itself and the rim. This friction in turn causes heat build up and the tyre then fails in spectacular fashion. It's very rare for this to happen on a car and wouldn't happen on a bike, due to a) the rider seeing/feeling the deflation and not going fast enough for the heat build-up.

People tend to use the term for any puncture that happens at a high speed or makes a loud noise, but they're wrong!

Here endeth todays lesson.
