So shopping for tires last week for my Acura, Walmart has a really good sale on some Pirelli Cinturato P7 tires (the best rated grand touring tire on Tirerack). About $100 plus cheaper than any other retailer I could find. I order them and have them shipped to my local store, which takes a week. I go up there today to get them installed, which takes about two hours. A little slow, but I'm not complaining since I did some shopping to kill time.
All is well. I get home. Look at the tires, and see that they have an "inside" and an "outside". All four tires were installed incorrectly, with the "inside" label clearly showing on the outside. DOH!!!
Back to Wal-Mart to get it corrected. To their credit, they got me in immediately without waiting and swapped all four tires to the correct mounting position. I also asked them to refund the $58 tire install fee for wasting my time, and they did. So the install was free.
So a little annoyed, but all in all it went OK.
