Being in the tire business (auto/lt. truck)..

Yep. the first pics are of a tire run underinflated/overloaded
The second is a classic brake induced flat spot.

Since anti-lock brakes and TPMS systems became common, that has cut the tires I see with those conditions by over, I would estimate, 90%

It still happens.. had both happen this week in fact.
First one.. guy had an ABS sensor fail, somone pulled out of a fast food joint in front of him, he flat-spotted a six month old tire.. brought it in for "warranty" with tread rubber smeared away from divot in the direction of the skid.. "I can't lock the brakes up, it's ABS!" "If the warning light is on, the system is locked out, sir."

Second.. tire with both sidewalls run to destruction. "Was the TPMS light on?" "Yeah." "How long was it on?" "Two, three days.."
