I just picked up 2 new sets of 4 tires each from Costco and I would definitely recommend them. Prices can't be beat, plus the convenience is huge, takes an hour to do the work if you set up your appointment earlier, the hour is easily spent inside doing your standard Costco shopping, easy peasy. Also, they provide a bunch of free maintenance which are walk-in style, and you can take care of them when you go back to Costco for your regular shopping.
