The fact it's done 27,000 miles?  Is this a front tyre?  I've never had
front car tyres last anywhere near that long.  15,000 miles, no matter the
car, and the buggers are dead.

Yes. Driving on it illegally, ie when it was worn down past the limit.

Tyres have wear markers moulded in. When they are flush with the tread the
tyre has had it. 27k is not bad for a tyre anyway depending of course on the
driving.

Novaboys get less mileage out of them than granddads.

Well, maybe. This Granddad struggles to get 10K from the fronts of a 1.8
Focus!

Just had new fronts on the rover 600. 42k on the clock and owned by my dad 
from new now mine. Original tyres

if it occurred rapidly to a previously apparently good tyre then overloading 
or low tyre pressure or massive misalignment or deterioration due to age.

What brand?

27,000 is a good life for an average compound tyre on the front of a front
wheel drive car. However, if rather than wear, the tread has actually peeled
off, then there are loads of possible causes, including manufacturing
defects, certain types of punctures, low air pressure, etc.

Don't know.  Astra 1.2, Skoda Favorit 1.3, Cavalier 2L, 406 1.6, and even
a Micra ferchrissakes!  No Longer than 15,000 miles for a set of front
tyres.

Was it on the front of an FWD car?

I suspect a manufacturing defect would have shown up WAAAAY before 27k 
miles.

My first suspicion would be damage that's allowed water in to the steel 
cores, which have then rusted and swelled.

You'd be surprised. AAIB reports of blown tyres on aircraft often show
failures are due to original manufacturing defects, even after several
retreads and many thousands of cycles.

The difference with road tyres (as well as a different usage pattern) is
that someone bothers to examine tyres for why they failed.

Obviously, post manufacturing damage is probably more likely, although even
then, tread shedding is often helped by poor adhesion or voids in the
tread<>carcass interface, which result from manufacturing defects.

What? I manage 15k easily out of the fronts on my 1.8 Focus. I rotate the
tyres front/back at around 12-15k and then change the 4 when they are worn
out at around 22-25k miles.

Ah. I only buy 2 tyres at a time. I rotate the back onto the front ever
other time or so, so they don't rot away before they wear out. This way, I
don't have to spend time with the jack and wheel brace. The tyre people do
it for me for free.

Grief. My Monsterheavy Audi 100 had new tyres about 8,000 miles ago and
still has 9mm left on the fronts.

I live in an area noted for its roundabouts, and I don't do many motorway
miles. I've tried rotating, but found that overall it didn't make much
difference to the miles/set. I also find that the rears on the Focus always
wear more on the edges, despite weekly pressure checks, and I don't like
putting these on the front. I have put 50% worn fronts on the rear, then
renewed the fronts but the wear rates don't always allow this.

Oh.... before the "new tyres to the rear" arguments start, I'm happier doing
it my way thanks!

The cheap and nasty tyres (30 a corner) I had fitted to the Xantia lasted 
20k plus or about a year's motoring. The Ceat ones I had fitted at Kwikflit 
seem to be holding up much better.

Even I get 22k on decent tyres, and that's driving like a nutter.

God knows, there's a small tyre place near Gloucester cattle market and I 
got them from there cos they were just about the cheapest ones around. They 
were truly dreadful in the wet but as most of my motoring is down motorways 
i.e. virtually straight line stuff it didn't matter too much provided you 
allowed treble your normal stopping distance. These Ceats seem to be ok 
though, a reasonable compromise of grip and longevity given that I don't 
throw the car around.

that sounds feasable  parking on the edge of kerbs can cause tread
separation ( if you are unsure what I mean look for a BMW) and splitting

And I manage 24K on GoodYear NCT5's on the front of a TDCi 115, which isn't

I beg to differ.

I got around 8k miles from the NCT5s on the front of my Passat 1.8T
before I switched 'em to the rear whilst they're still slightly above
the wear markers.

How you get 24k from a pair, I'll never know.

8K?! Jeepers! Well, my 24K's consistent over two sets of NCT5's, 195/60 VR15 
if that makes any difference to the comparison. Mixture of motorway, country 
road, and town driving, generally done in a press-on, but not wasteful, 
manner. If I recall correctly, I got about 15K out of the original Michelins 
on the car. Always been well pleased with the wear on NCT5's. They lack grip 
a bit in the wet, especially when combined with the torque output of a TDCi 
nipping out at a junction, for example, but as long as you're aware of that, 
its managable. Paid 65 each for a rear set a while back, and will shortly 
be doing the same for the front. At that price, and about 24K, I'm more than 
happy.

I'll confirm your findings on NCT5, last ages, low wet grip, not good on 
smooth slippery roads either.

Over the last few years I'd rank the tyres I've used like this (first is 
best / quitest / cheapest etc.)

Grip: Conti SportContact 2, Toyo T1-S, Mich Primacy, Conti Premium2, Conti 
Premium, Pirelli P6000, Dunlop SP3000, Mich Energy, Goodyear NCT5

Life: Energy, NCT5, Primacy, Premium, P6000, SP3000, SC2, T1-S - Premium2 
not yet worn them out!

Noise. Premium 2, Primacy, Premium, SC2, T1-S, P6000, Energy, NCT5

Price. NCT5, SP3000, Energy, T1-S, Premium2, Premium, SC2, Primacy

I'm so far happy with the PremiumContact 2, cheap enough from Mytyres.net, 
very quiet, very grippy - as long as they last as long as the Premium 
Contact I'll be happy...

I had NCT5s on the 740i - very quiet[1], not *too* bad in the wet[2],
good turn in/responsiveness, slow to wear.

The front pair were a distress purchase and sufficiently OK for me to
get matching rears a little later.  I don't think I'd choose NCTs over
P-Zeros or especially Michelin PS2s normally.
