This tire got drove in while it was flat I think? I’ve never seen wear like that

Gf called me this morning saying she’s got a flat tire but couldn’t find a puncture or anything (3rd time this year but different wheel this time). She couldn’t get it off cuz it was siezed on so I got it off when I got home. She says she drove a few blocks this morning and it was fine but then when she was about to leave for work it was flat, about an hour after she got home from the first drive.

I’m thinking this tire has been low for a while and she just kept driving on it witbout realizing. Last weekend she made a road trip 100 miles or so and I’m thinking it was low for that whole drive.

2016 focus with the 2.0 or whatever it gets. Doesn’t really matter but the bot told me so
