found a good website that talks about uneven tire wear..

http://www.aa1car.com/library/tire_wear.htm

still make me nervous about what is going on back there.. I am just skeptical its just an alignment. I'm sure there are bushings or struts that are worn. My biggest fear is the strut tower is leaning... look in the beginning of this thread.. did that rust damage the strut tower? Then what.. I scheduled a free inspection to have them look at the car. maybe it can be fixed with a simple alignment. and of course new tires. Found some used Goodyears RSA's 245/45/18's... might work and save me some money..
