@RoboticistDuck @linear @justinto well, that's another problem, yeah.
I don't think tire mfrs are sandbaggimg here. You can build a harder tire that doesn't wear as fast, but you lose road grip/traction as well as ride comfort. And yeah, the tire material has to be softer than the road surface, otherwise you get pavement particles thrown into the air, and have to repave more often. It's all a bunch of tradeoffs, not at all as nefarious or cut and dry as you think.
