Back in the old days you didn't need to "check your tires" because it's flagrantly obvious visually and in terms of handling when a tire with a 65 or 75 aspect ratio is low.

On bias-ply tires from ‘60s, sure. You’re not going to visually check tire pressure on radials, at least not with any accuracy.

Back in "the day" (so like 80s on down) everyone ran their tires to failure (usually bald, but often blowout as well) as a matter of normal practice,

That’s just old man “kids today!” bullshit. I was an auto mechanic in the ‘80s, and the only people that did that were very poor or very stupid.
