There's tons of variables, camber, caster, tires, tire tracking or drift. However, what's better to run a little toe in or toe out. My car had a quarter degree of toe out on each wheel and pulled to the right. I switched tires and now it pulls to the left. I had an alignment, they put toe at 0 for each wheel and stills pull to the left. My camber and caster is dead on they said. I'm wondering if I can tweek it a little so it doesn't go left. I have no issue with tires wearing uneven.

 

If you want it to track straight more easily, then toe it in a little. Zero or toe out makes it turn quicker but also makes it wander with the slightest imperfections in the road. Also, check your tire pressures.

 

went to have mine done, told me the same thing, also wanders the road....
