Rodney,
I haven't had this happen to my "B" yet, but in my other cars,
severe tire wear on the insides has often been due to spring wear,
especially on the rear end if coil springs are involved. I think this
is because as the springs wear and lose "springiness", if that's a word,
the car starts to "hunker down" between the two springs, transferring
weight from the outside of the tires to the inside, essentially
increasing the amount of negative camber. (i.e., the tops of the wheels
are now closer together than the bottoms.) Alternatively, a PO may have
installed negative camber A-arms, but this is probably not likely.
I don't remember what the symptoms are of incorrect toe-in, but I'm
sure somebody here knows.
