Alignment for Mileage?

I'm having my front tires replaced tomorrow and getting an alignment. A pothole broke the casing in the right tire and the left is wearing on the inside. I've been doing a little research to see if there are settings, outside of factory spec, that will provide better mileage. Anyone have experience with this in the Cobalt?

Fr3AkAzOiD: I came across a post from you on a different forum - I had mine done a few months back. Didn't take it all the way to 0 toe but the front was at 0.13 per side and I had them bring it down to 0.01 per side.
For the rears I had to get a shim kit as the alignment is not adjustable but I brought it down from 0.22 to 0.06.

Are you still happy with these settings?

Thanks!

I changed brand of tires at the same time so can't calculate how much mpg improvement was from the alignment alone but overall I'm happy.

This change will limit how much canyon carving you would be able to do so if you like going fast through the twisties you may not want to take it as low as I did.

I don't do much in the way of high speed corners now. Most of my driving is light throttle. But, I do miss the days of popping in a good CD and hitting a local deserted highway late at night for a 160+ MPH blast. Sigh... maybe I'll be able to do it again someday.

One thing that I've read that makes sense is that they should do the alignment with the driver in the car. This allows the suspension to be weighed down close to what it would normally be.

Never heard that and I doubt most shops would allow it due to safety issues.
Makes sense though.

I'm running 43psi cold (max on the tires is 50psi). Had the alignment done today and set the toe to 0. Feels fine to me. One of the wheels had thrown it's weight so now there is no vibration. Feels like a new car.
