Why does 225/45 R19 pressure vary?

Even though many cars share the 225/45 R19 tyre size, the recommended pressure depends on:

Vehicle Weight: A heavier car needs more air pressure to support its mass and maintain the tyre's shape.
Load: Carrying passengers or luggage significantly increases the required pressure on the rear tyres.
Handling: Manufacturers tune tyre pressure to achieve specific steering response and comfort levels.
