Quick Stock Alignment Spec Check
 

I have, like some of you guys, pretty severe (front) inner tire thread wear. It comes mostly from toe and camber, more so from toe, even though I thought that my toes were always in spec, so I decided to bring it in for an alignment check.
The first number in each category was the spec BEFORE October 2012, the second number is October 2012, and the third number in red was today. Camber looks good to me, so I am wondering if it's worth fixing the toe, especially in the front.
From my understanding, a toe-in spec like front left is not optimal, but shouldn't have caused this much of tire wear. Of course, it could also be just from the negative camber.

Tire is 1 1/2 years old, 14k miles, and bought in october 2012, right before that alignment. Thread looks good on all tires, except for the front inner side, where there's only 4/32 left, more or less.
What do you guys think? Thanks

FRONT LEFT

CAMBER -1.2 -1.3 -1.2
CASTER 8.2 8.2 ()?
TOE -0.05 0.08 0.20


FRONT RIGHT

CASTER 8.0 8.0 ()?
TOE 0.05 0.01 -0.05



REAR LEFT

CAMBER -2.6 -1.7 -1.7
TOE 0.04 0.02 0.17


REAR LEFT

CAMBER -2.1 -1.6 -1.6
TOE 0.22 0.09 0.05

With the stock setup that's pretty much the best yer gonna get. In all honesty I think you should do a complete suspension overhaul with adjustable aftermarket parts if you're really concerned about alignment. It will save you money on tires in the long run.

In addition, toe causes accelerated tire wear, camber doesn't accelerate tire wear it just adjusts where it will wear.

Your toe numbers should look more like this tho:

front R: 0.5
Front L: 0.7
Rear L: 0.15
Rear R: 0.16

TOE kills tires. Make sure to have your toe as close to 0 as possible.
