What caused this?

[Mac Romans]

I parked my daily diesel today with the wheels turned and caught sight of some damage to the inner edge of the tyre. I swapped it on to the spare (which is a bloody space saver) as this is clearly dangerous.

I had no inclination there were any issues and the wear on the tread seems even, yet the inner tyre wall is shredded.

I inspected everything in the arch whilst the wheel was off and there’s no evidence of the tyre rubbing on anything there as I’d expect to see a polished or at least clean area where contact was made.

So my question is...what the hell has happened to the tyre?

Looks like it been run flat at some point

Is your other car an x-type Mac?
The rear suspension has radius arms which the bushes collapse on worth checking these out.

Tony.

ps. Is the other tyre showing similar wear?

Yes mate, it’s an x type. This was the front offside wheel. The nearside wheel is flawless which has got me scratching my head.

I didn't read your post properly mate , now I've seen "wheels in lock". In that case I suspect that Sean has hit the nail on the head. The tyre may have been run underinflated at some point and possibly had a slight bulge in the tyre at that point.

Been in the garage recently on a ramp / rolling road? Other possibility could be dropping down a kerb or pot hole edge?

My initial thought to was it had been parked right on the edge of a kerb and dropped off or driven off. That said I wouldn’t expect to see that amount of damage. It has been driven hard against something to remove all the rubber down to the cords. I’d guess at a nasty steep sided and long pothole at speed has just torn the edge off.

There's no damage to the wheel rim though. Pure tyre wear from underinflation.
