Nothing to worry about.. I only put about 11k a year on a car regardless. Between taking her to work most days and the 2012 about twice a week and weekends the blackstang only has 3200 miles on her so far. Just something about those 2000's eat tires and no I don't corner hard at all unless it's an emergency. Figure I'll get two more years out of this set then I'll probably retire her.
just for the hell of it, snap a pic, and post it. usually we can give you an idea of any possible alignment issues just from seeing the wear pattern.
also, if you had her aligned by a chain type of shop......go find a mom and pop shop, and have them check it. there's a few things that they'll know that the monkeys at the chain types don't.
