If the toe is off, you'll cup the tires.
If the camber is off you'll wear the inside/outside edge but not with cupping.
Caster doesn't really kill the tires that I know of.
So, set the toe to -0.01 on front wheels (+/- 0.0) Rear gets 0.0
Set the camber to -0.1 on all 4 wheels (+/- 0.0)
Set the caster to stock.
What do you use negative camber for? Think about it.... You want the tires to present a flat foot print on turns, yes? No? When they want to go really fast in the turns, the camber is set to a higher negative number, yes, No?
I suggest "yes" to those 2 questions. So, what does negative camber do to a tire that is running straight down a superhighway? Think on it a sec.... It ***** the wheel to put more pressure on the inside edge of the tire. Where is the "bad" wear the horror stories have complained about? The inside edge of the tire is "down to the belts" and the rest of the tire is great. Sound familiar?
Yeah, yeah, almost 0 camber is horrible!!!
Think about this... A solid rear axle has how much camber? I'm thinking 0. Does a solid rear axle wear out the inside edge of the tires? I'm thinking, no.
So, in conclusion and before I put on my asbestos suit, I will set my toe to -0.01 my rear to 0.0, my camber to -0.1, and the caster to the stock number. I'll continue down life's superhighways in ignorant bliss with the top down and a smile on my face.
If I were to go racing, pylon crushing, or X-Cross, then I'll crank in the negative camber, -2.0 or whatever, and go for it!
My last set of tires (Goodyear GSD3s) got 35K+ miles.
