Should work the same for a bike. Overinflated, it will wear in the middle, underinflated it will wear on the outside edges. I’ve been doing it thaat way since the late 70’s, works perfect. I just watch tire wear. Adjust accordingly.
I have no idea what the sticker on my car says. Tires say 35psi, with the PTCruiser I’m in now, 30psi seems to work great. Jeep Cherokee I had before liked 28 a lot better.
Bike tires are completely different animals. Round, not flat like car tires. Air pressure is most important for traction and handling - and safety of course. You’d get handling problems long before seeing any wear issues. That’s my opinion at any rate.
