Funny enough, I was shopping for some used tires to put on my 05 Grand Cherokee, I went to the pretty good Les Schwab location by me in North Portland and the sales gal said I would have a hard time finding used tires in either 235/65/17 or 245/65/17 because they are a less common tire, so I said OK, lets look at new. The 4 options they had in stock, were all overpriced, so I told her I'll take my business elsewhere and she was surprised for some reason. Which is weird for this location, I've been there before and they were a bit more helpful.
So I checked out Discount Tire, which I always had good luck with. Didn't have anything used, but they did have a good deal on the Atturo Trail Blade A/T in my size, but the manager found out the computer was lying and he had only 2 in stock, and couldn't get more in till next week. But chatting with him while he was having the employees scour the store for the other two, I mentioned the fun I had at Les Schwab earlier, he knew some of what going with them. First problem was that they started having employee issues, namely the lawsuit regarding the favoring of men over women in hiring and promotion that actually opened up a lot of dirt about how the company operates when Les isn't looking. Second was they managed to start managing to annoy long time tire maker Toyo; from what he understands, Toyo wanted them to be a full Toyo dealer and actually honor the manufacturer Toyo warranty no matter where they bought the tires instead of just their house tire guarantee. They didn't want to do this as it would cut into their high margins due to their previous arrangement....so it lead to their tire inventory changing. Thats why oddly you now see Goodyear and Firestone tires for sale in Les Schwab.
