Cause they couldn't read the door Jamb sticker?

Seriously, most car and tire combination's have a sweet spot they work best at. Different tires than engineered and spec'd on the car may have softer or stiffer sidewalls that may require a change in the pressures. IMO the factory recommendation with these tires are pretty spot on. Raising them to 40 will result in a reduced contact patch, sketchier braking and traction, and odd tire wear patterns.

The Tyre Bible is always a good read if you haven't done so:
