A mate of mine was stuck on the side of the m4 for a few hours last night when he suffered a double puncture.

This morning he's got a good look at them and they have split wide open down the side wall, seemingly a complete catastrophic failure of the tyres.

He tells me the tyre pressure system didn't alert him anything was wrong until the failure.

Both tyres were brand new Yokohamas and only fitted on 28th December.

Anyone heard of this happening before? Any idea what could cause it? Or is it just a manufacturing fault?

My best guess would be the garage massively over-inflated them and then reset the monitoring system.

It’s not a good photo - I can’t see for sure, but it looks like the tire has been scored almost?

Are the two punctures on the same side of the car?

I can't see what would cause two tyres to simultaneously fail, except for running over something in the road. Even if there was a manufacturing defect, to fail in such a synchronised way would seem massively unlikely. Or did your mate have one puncture, stop and change the tyre, and then have another one later on the same journey?

Tyre fitter using fitting machine incorrectly?

Surely that'll be from the deflation and driving at speed on a flat?

Yes that's certainly possible but, would tend to suggest a sudden loss of all pressure.

correct. drive long enough on a flat run flat and thats what you end up with.

Almost certainly he's run over something. If he wasn't on the side of the M4, I'd say that is classic damage from whacking a kerb.

Hi there I would contact the manufacturers UK rep they are usually very helpful. And they are very keen on possible manufacturing issues. I had an issue with a Toyo tyre and they were interested sent me a form to fill in and helped resolve the issue.

If it had been driven flat you would see marks all around the tyre wall. They look like big splits in the rubber.

Where did get the tyres?

Surely he should be going back to the supplier?

He will be, it only happened last night.

I was interested to see if others had seen anything like this, I've not.

It’s a standard failure mode of running on a deflated/deflating tyre. The rim will eventually cut through the sidewall when the pressure has dropped enough.

When the tyre is removed, you’ll see all manner or rubber crumb and chafing of the inner liner from where the rim has eaten into the tyre because they have come into contact.
