Hi Run tire steel belt damage (Hi Run ST175/80D13) question

Not a tire expert (or on much of anything else), but looking at the two tires side by side, the damaged tire looks really worn. Seems to me to be a lot more than it should for only 2000 miles.

I'd have a look at your axle alignment.
Then, there is always the Chinese ST tire issue to consider as well. You may have hit something, but I don't like the looks of the side wall split. That aside, way too much wear for such low mileage.
