Inside tire wear on the front.
Camber alone is not an issue unless you are one of these idiots:
Even this car is a bit extreme:
I've run between 3/4 degree and 1.0 degree of negative camber in my cars and trucks for literally hundreds of thousands of miles....
It isn't the camber that gets you. It is the toe setting. Toe IN will wear the outside, toe OUT wears the inside.
Toe is easy to check if you have the tools.
I bought toe plates to do the job. They were under $40.
They go like this:
You hook the tape measure in these slots.
Then you compare the number on the front tape to the number on the rear tape. They should be 1/8" apart with the bigger number at the rear tape.
