I believe rider weight/mass has a lot to do with tire choice. Noticing in the few groups I currently might ride with, that larger riders, on newer bikes, will have wider tires. That makes sense. One can have a nice riding tire, without it being rock hard, with the wider tire.
For lighter riders there's less perceived difference. Sure they can ride at lower pressures, but may already be on lower pressures on their narrower rubber. I ride 23 & 25 (usually on the rear) at 72 frnt and 75 rear, and they're plenty firm for me. I rode a friend's bike which had 32s on it, and really didn't notice any real difference, he had his pumped to 75 & 80 - also seemed firm...
The young guys in those groups who are very strong riders ? 25mm almost exclusively... roadies... not grvl or touring ... err bikepacking... LOL!
Ride On
