Only one tire wearing excessively HELP

Well, I'd certainly guess you've got alignment troubles. Could be due to either a 'way-off alignment adjustment or a worn-out or bent-up part that affects the alignment (be it a suspension part per se or something that these parts attach to).

Was an alignment done along with the new tires? I've certainly seen tire shops screw up an alignment in this way, and yes, the overloaded edge can wear out in 5,000 miles or even less. (Clown who did that to me didn't fully torque the lug nuts, either! The manager gave me two new tires as well as free re-alignment, and identified someone who was having a better day to perform these tasks the second time.)

Had your car been in an accident, or run up on the curb hard or something like that?

It is possible to align a front end oneself without a machine, but the skill and patience required is such that most people just take it to a shop that has a machine. Look for local references so you get a shop that has the competence and honesty to diagnose and fix a potential front-end hard-parts problem, should they end up scratching their heads with respect to making it hold alignment and have to look for wear or damage instead.

Best of luck,

You need an alignment. This is a case of penny wise and pound foolish...

either a bad wheel bearing cocking, should hear a lot of noise . or a major camber problem. take it to an alignment shop. Chip

The poster doesn't state mileage. You have to suspect a worn part there, especially with no grease fitting. Lubbed for life means 50K these days. The problem should be real obvious and should have been diagnosed when the first tire became worn.
