it has to do with the angle between the point the tire pivots (steers) on and the point the wheel spins on. The steering point needs to be forward of the spinning point to help the car go straight down the road. Think of a shopping carts front wheels (they’re called casters), and how they’ll pivot around with the direction you’re pushing the cart. That angle can be adjusted so the car tracks properly…
oh for real… I’ve always wanted to ask them what they thought the underside looked like. I picture their simple minds imagining something like loose dirt clods falling off and maybe some roots and shit sticking out like I would have when I was a kid…

the over and under-inflation wear isn’t as much of an issue these days as it used to be. In the old days of bias-ply tires, that was definitely the case. You could have a low tire and hardly be able to tell, because the stiff sidewalls would hardly sag. Their flex point was down the middle of the tread. Radial tire construction puts the flex point in the sidewalls, which doesn’t distort the tread as much, plus gives a much smoother ride…
