I just watched another video of a rear tire change. Getting ready to replace mine.

Any how, for years I've loved the feeling of a new tire after my old one had worn to a generally flat tread. So, I'm watching this guy replace his tire with a car tire, and I'm wondering how that square-ish tread must feel when leaning into a turn. I mean, I can tell when my tire is worn, because I have to coax it up onto that 'edge' from wear.

Can someone tell me how you dark siders do it?
