Structural tyre failures
Discussion
Over the last few weeks I've noticed a lot of whole tyre treads resting on the hard shoulder and central barriers of the M1, M25 and M11.
Nothing unusual here, lorry debris is everywhere. But then I realised these tread sections were car sized. Strange goings on, not seen many of those before.
Then I had a passing car lose the tread from one of its tyres right in front of me. A chunk hit my car but the tread came off in one piece and the driver moved from lane 3 (of 4) onto the hard shoulder with little fuss.
This reminded me of some budget tyres my son bought a year or two ago. They developed cracks on the outside edge of the tread after very little use. I had one of these deflate rapidly at around 80 on the M1 and the tyre was destroyed, so I couldn't see if it had developed cracks.
I discussed this with an independent tyre retailer, who reckons a manufacturer in the east is making tyres without tread, then moulding in the name of your choice and attaching one of several tread patterns, thus giving you your own brand of tyre to sell to the world.
I have to wonder if these failures are down to such manufacturing techniques. If so, it's a little worrying.

That's nothing, at least they are new. You can get re-treaded tyres which use 2nd hand carcasses!Nothing unusual here, lorry debris is everywhere. But then I realised these tread sections were car sized. Strange goings on, not seen many of those before.

You wouldn't want to know how aircraft tyres are made then....http://tyresdirectuk.co.uk/faqs.php

Yes, but why the sudden proliferation? Neglecting tyre pressures in not new.
Money.People are running their tyres lower and lower, and now when they're told at their annual MOT there's 3mm left, they leave them instead of changing them.
Naturally people never ever check their tyres for signs of wear, especially the inside shoulder where they usually wear a little more so we're seeing peoples cost saving attempts put themselves and others as risk.

tty budget tyre but otherwise I'm lost.I do some pretty extreme things to tyres and even posh tyres can delaminate and throw the entire tread off if you get them hot enough - I have scratch marks on my roof from a delaminating bridgestone which couldn't take the heat of extreme abuse.
I'm sure you can get a similar amount of heat in to a tyre by running it a very low pressure, rather than my method of driving at a silly angle to the direction of travel.

Maybe you didn't notice them before, and now you do you see them all the time?Or the world has changed.
Of the two I suspect it's the first reason, but it doesn't hurt to check the world every now and then, just in case.

You've got some snot on your tie...

Also I'm not wearing a tie as I'm on suicide watch following no ROFLs for a pun in the Lotus forum.

A fair percentage are caravan tyres which are neglected, under-inflated, overloaded and have perished sidewalls. A bit too much heat caused by the first high-speed (relatively speaking) run of the year and one or more of the tyres gives up the ghost.
It's a common failure for the tread to delaminate if the tyre is subjected to too much heat. Unless it is noticed in time, it may well fail by flinging the tread off. Lorries (or, more accurately, trailers) are famous for it too, when the driver doesn't know he's got a deflating tyre. You do not ever want to be alongside one when it goes bang, I promise you. Adrenaline is brown.

I watched an episode of mythbusters where they proved a fragment of a delaminated truck tyre can smash through a car window and decapitate the driver It's a common failure for the tread to delaminate if the tyre is subjected to too much heat.
