Disintegrating tyres !! Has this happened to others ?

Has anyone had their tyre tread completely disintigrate whilst driving. Happened to me on motorway and flapping tread ruined rear panel etc. AA said they have never seen the like as inside of tyre was still fully inflated.

Welcome to landyzone drooling ol' duffers. Tyre shredding only effect remolds as they can harden and degrade. The glue that bonds to the original machine scoured tyre, will breakdown as heat build up when used at higher than recommended speed. Ergo the outer tread demands. That's why many companies trailers have remolds but fresh on the tractor units.
Old new tyres harden, from the supplier after few years sitting on the racks, can show cracking on sidewalls.
This is why they recommended at safe speed limit to the tyre used.

Hello and welcome
i have had a tyre on the back of my van do that and it it was not a remold as far as i know

Defo not a remold. Pirelli fitted from new when I bought the car 2 years back …

Welcome to LZ!

You might do better to post in the vehicle specific section appropriate to your vehicle about this.

And when you get there, give a bit more information, such as what sort of vehicle you have, what usage it gets, whether the tyre in question was new or second hand when fitted, and how often you check the tyre pressures.
Even quality tyres will get the very occasional duff tyre in production.
But most problems are caused by operator error, mainly under inflation, often due to leakage of air around alloy rims, but also using mismatched tyres, critical on a 4WD, or using tyres that have had too much exposure to direct sunlight, or other causes of premature tyre ageing.

Date code off the tyre? new to you does not always mean new if you see what I mean.
Pirelli are a bit crap, 15k is what I got out of a set on my D3, their AT ones were better.
