Toe-in has to be measured. IMO you cannot 'drive around' and adjust the toe-in settings along the way just until 'it feels right'.

If the insides of the tire(s) are wearing fast in just a couple of days/weeks, you probably still have a lot of toe-out.
Toe-out WILL make the car feel 'touchy'.

Does a front tire squeel easy while sharp cornering at moderate speeds?
