I run my Warrior 800 at 12 PSI,
I almost never run any of my tires at the tires max pressure, that pressure is for when the tire is loaded to it's maximum capacity.
In general, The tire sidewall pressure is the maximum rated PSI for that particular tire. Not for the vehicle its mounted on. For most vehicles, tractors, etc. the manufacture sets the recommended pressure for that specific machine and tire combo. Check the drivers door jamb or owners manual for proper recommendations.
A car or pickup with 44# is one jittery ride and poor performing tire & handling.
