total toe needs to be set as close to ZERO degrees as possible.

or you will be feathering the outside ( or inside ) edged of the tires.

How much psi in your tires?

You can buy a set of camber bolts, take them to you local alignment shop and have them add some more negative camber. Would also make the car handle better. Where are you located?

The alignments from the factory can be realy far off. You can check it with a measuring tape if you suspect that the toe-in is out of spec. You measure the distance between one tread block on one tire to the same tread block on the other tire. Do it on the front of the tires and compare it to the same measurement on the rear of the tires.

If the front measurement is a larger number, that is toe-out. You would be scrubbing off the insides of the tires driving straight down the road.

If the measurement is bigger at the rear of the tire vs the front of the tire, that is toe in. You would be scrubbing off the outsides of the tire treads driving down the road.

Normally the car would be set up with just a barely measurable amount of toe-out.

Camber as shown in the diagram above will wear tire too, but much less than the toe being out of whack.

Yeah, 32psi shows alot of outter edge wear on mine too. try 35-38psi & see if it improve your tire wear.
