So - wife needed new tires on her Expedition. I was out of town but told her to go to Discount Tire and get Hankook tires. She went to Tire Works because it was closer - they didn't have Hankooks but told her they had Sunfull - which were cheaper and better. This was not correct. They were the worst tires I have ever had - severe under steer and any imperfection in the pavement would launch you in a new direction. Tire Works was great! They swapped me out for a new set of Kumho tires and only charged for the difference in the cost of the tires. It was basically hassle free and no argument. Only delay was waiting for second demount and mount. It's nice these days to find an organization that will admit mistake and make good on a deal. Really good customer service - it's just too bad that they got sucked in by the incorrect promises made by the tire maker. Follow up - a couple of days later got a low pressure warning and the front end began to shake badly at 50 MPH. Two broken retaining bands on the TP sensors - Google why this occurs and you will understand why I went to a different tire store for repair.
