Joey: just curious - in your opinion - when would you expect to start seeing uneven tire wear from excessive negative camber?

Here is my take.
Negative camber will wear the inside edge of the tire faster than the outside. I assume once I can visually see a difference then the extra wear has become significant. Eye-balling my tires, i don't see any difference after 13k miles. Below are pics of my front and rear left tires. The first 2 pics are my front left, and the 3rd pic is my left rear. I always keep my pressure close to the recommended/minimum, around 33lbs-34lbs, so I always see the outside edges wear faster than the tire center.
I just measured the tread depth with a cheap tread gage - 4th pic.
On the front left tire it does appear my inner tread depth is about 1MM less than the outer tread depth. If I take the measurement on the inner edge, I have 4MM remaining. On the outer extreme edge I have 5MM.
So I would say the negative camber has taken a 1MM toll on my tires.
The center of the tire is around 6MM. From the Toyo website, a new tire has 11MM tire depth. If the 11MM is measured from the center of the tire, then I have 55% remaining. If measured from the outer edge, then I have 36% remaining.
I measured the depth of the rear tire and I did not see as big of difference from the outside and inside edge. But I periodically rotate my tires front to back, so I am not sure how that is effecting the measurements.
If I only have 36% remaining, then my guess of 20K total wear is fairly accurate.
I am now guesstimating I could lose 1K to 2K of tire wear/usage due to negative camber. But that is a conservative SWAG. It probably is less than that.
