I bought a set of Michelens from Costco when they had a coupon. One thing about Costco is that they are always crowded and they are so ssssslow. When I get the tires rotated it sometimes takes 4 hours. The last time I rotated them I had to go back and re-balance them. Which they did, no charge, but a bit of a hassle. Most tire stores are a hassle, just expect Costco to be a slightly bigger hassle.
