Source of unusual tire deterioration
I moved a set of steers to the back. The one that was worn the most has developed an odd patch of unusual tire wear, almost as if it has been attacked by a chemical that is breaking down the rubber. It looks dry rotted but is soft and crumbles off when you rub it.
It's not terribly urgent as the tire is nearly at the end of it's life, but i've never seen anything like this.

Is this a worthwhile discussion?
