When you’re on the shoulder of a rural highway, and your tires are sinking-in, robbing you of your strength, while you’re going nowhere, due to having to plow through the mush, you needed bigger tires.
Depends on the purpose, obviously.
if one is wanting near-zero rolling-resistance on smooth pavement, then get the narrowest, highest-pressure tires one can, obviously.
But rurally?
Even as a courier, I needed min-37mm or 43mm ( can’t remember which ) tires, in order to not have a wheel grabbed by a sewer-cover/grate, in traffic.
On my regular unpowered commuter I’ve always had around 2" tires, but its unusuable in something like sand while my ebike with 4" tires do just fine.
