I had 4 tires on my car. Four were dry-rotted, The left front was bald, 3 were at wear indicators, and one was almost to it's wear indicator. I don't know how many miles were on each tire because I didn't put them on there. So overall uneven wear per tire is not a factor.
Anyhow, I just replaced them with some Pole Positions and made a nice difference in everything.
My front left tire was bald, but the inside of it was shot - down to cords - 2 days away from blowout. Lots of inside wear.
I got an alignment to check the numbers and have the toe adjusted. Just in case suspension sag + some toe out = worn inner.
Here are the numbers. What do you think? What is an SAI? How do these numbers compare to your other 9000s? Is there a problem here? Why the before and after variance on Camber and Caster Font and Rear when you can not adjust them? How does the car maintain it's high speed stability without lots of caster? I think BMWs and such run 8-10-12 degrees, but they are RWD>.
