They can be a little hit or miss from store to store. The one closest to my house is a shit hole, while one maybe a half mile farther is fantastic. I have bought 5+ sets of tires for various cars from them, and they've always treated me great. I have never had to "remind" them that the stock wheels are directional (I was watching out for it, but they knew). They've always rebalanced for free, no questions asked, and the road hazard warranties have been used a few times with no sweat on my part.
My suggestion, go into a couple of different Discount Tires and price things out with installation. Mine will match Tire Rack's price. And you have the advantage of working one on one with the same dealer from tire purchase to installation.
