As I said previously, obtaining and setting
factory recommended tire pressure is a
start to checking how the vehicle handles.

Secondly, get it aligned. Make sure all
adjustable parameters are in the middle
of their specified ranges, even if zero
degrees is not in the middle.

Finally, once alignment is done, and it
still doesn't drive as expected, or tire wear
is still happening, then you have damage -
bent or worn parts. Wheels could be
perfectly aligned, but be in the 'wrong
place' on the vehicle: setback, where one
wheel on the same axle is ahead of or
behind the other by fractions of an inch.
Or, another wheel higher or lower than
the others due to spindle or body/frame
damage, etc.

In the front, this could mean poor return
from turns, or bad Ackerman angle. In
the rear, it could mean thrust angle
issues.
