Not completely true for front end parts. Low tires give more turning resistance especially at slow speeds and parking lots. Low tires put more strain on inner and outer tie rod end and idler and pitman arms and steering racks too.
I run mine at 35 PSI max. My previous Ford I'd run at about 32 PSI for 16 years.
The more pressure you put in tires, the harder it will be on suspension components. Whatever fuel you'll save by running high pressure will be pissed away every time you'll have to do a ball joint, strut or wheel bearing prematurely.
Now, I'm not too familiar with the skinny tires on large mags (never had them, never will), but I believe these will require higher pressures by default, as not to damage the rim on every pothole. These types of wheels really do a number on the suspension components, though... especially on a big & heavy truck.
