I am replacing the tires on my car, and while examining them found a very interesting thing on just one of them: the treads are worn out only on the center band but not all the way around. I know that if only the center of the tire is worn out, it might indicate that the tire is overinflated. But what doesn’t make sense to me is that the wear is uneven around the tire. One side has no tread left at all, while the other still has about 2mm of depth left. Just curious how this happens.

Note that at the top, the tread is gone completely, while at the bottom you can see it gradually coming back. The other side of the tire (on the ground in the picture) has even more tread.
