Tyre failure and tyre liners

I had a substantial tyre failure today - see pictures. Ended up with
a large bit of tread missing and a gash right through the cords.

I ended up with a large egg in the tyre with a distinct lump on each
rotation.

The point of this is that I was only saved from a blowout by the Mr
Tuffy tyre liner inside acting as a tyre boot. This is a benefit of
tyre liners beyond the prevention of punctures from "just penetrating"
objects that is sometimes missed.

Another side benefit is that any punctures (the only other one in this
tyre in over 3000 miles was caused by a large nail that no reasonable
precautions could prevent) tend to self-seal to some extent, leaving
you with a slow puncture that can be sorted when convenient.

Does anyone have any other evidence to support these comments?

My final point is a comment on the threads about tyre longevity. I
rarely wear down tyres, much more usual is this sort of sudden failure
- as you can see this tyre still had plenty of tread left after 3300
miles. So my answer to those who ask "how long can I expect my tyres
to last?" is "until you run over something that shreds them". Does
anyone else subscribe to this view.

Don't know what caused this puncture(dark & wet - I didn't see what
did it), but I'm certainly glad to have been saved from a long walk (I
carry spare tube, but not tyre). One up to tyre liners on this
occasion.

See! The alien has either taken over your mind or your newsreader,
forcing you to post it TWICE!

So many large images of such an ugly tire must be an abuse of broadband.

In West Texas, some would refer to that as a rockadillo bite. Is
there an analogous creature in your environs, perhaps an elusive
butyliverous form of mutant hedgehog? The tread seems to have been
not so much punctured as nibbled out; it looks like the Python Killer
Rabbit had had a go at it.

No worse than riding on the typical factory-trued wheel on a
mass-market bike, then.

A narrow miss indeed.

Having used no tire liners in a long time myself, I can only stare in
awe at the luck of a fortunate Brit.

About two-thirds of my re-tire-ments over the years have been due to
what the car tire dealers refer to as "road hazards", but about one in
three used to last long enough to actually become worn out. Since
getting back into the cycling habit in the past couple of years, I
have not yet accumulated enough miles on any single bike to wear a
tire severely, but I have had to replace several due to damage, and a
few due to their having become overly old and dryrot-split before the
bikes came into my possession. As such, I'd say that your observation
is probably applicable to a good many riders.

My mind is OK (or it was last time I got it out of the jar to look at
it) - but you must be right about THE ALIEN - it must the one that
gives the "ATM cable unplugged" and "post error" messages - any tips
on how to exorcise it? .

My broadband connection has the odd quirk that ftp always seems to
work while web pages often fail to download properly - I've got to get
my money's worth some how!
