i feel dumb for paying $249 for an alignment at my last visit, but i just reached 20k miles and the rear treads are running low and i figure i will be replacing tires soon so maybe an alignment is a good idea anyway. (and of course the SA has been suggesting it since the last visit)
nothing was wrong with it before, the wear isn't uneven or anything. no pulling while driving, etc. but i did hit a huge pothole a few months back that scared the crap out of me and i was shocked it didn't damage the tire or wheel.
just seemed like maybe every 2-3 years is probably ok to pay for an alignment to make sure it's not a little off and ruining tires prematurely
