Jim,
Definitely sounds like alignment problem. If the wear is equal all the way
around the inner circumference of the tire (no hills and valleys so to
speak), then one or two adjustment angles are out of specs. Either camber
(top of tire leaning in toward the car too much) or toe is too far out. You
didn't mention any handling quirks so I would assume that camber is the
problem, predominately. Another check is to closely examine the tire wear
and look for "feathering" toward the outer edge of the tire. Caused by the
tire sliding while it is rolling. This would indicate a toe problem. I would
have thought that you would have felt some steering and handling problem if
this was the case however. Time for an alignment. Be sure the shop
thoroughly inspects the front end for worn, wearing, or damaged parts before
doing the alignment. Cheers.
