The tire doesn’t look flat to me. Not even on the bottom.

Try looking at the original Daily Mail photo. Here's a 4X enlargement
of the tire contact area:

It might not be flat, but rather the weight of the vehicle might be
pushing down on the rear wheel. Or, it might be an indication of a
Photoshop edit. The tire doesn't look quite right to be a flat tire,
which would show parts of the tire pushed outward to both sides of the
contact area. However, I'm not familiar with that style of rim, so I
don't know how the tube and tire will act when flat.


Looks more like an uneven road section in this picture.
