I purchased my XLT in December 2006 and loved it until about 35,000 miles. I began to notice a lot of road noise from the tires due to excessive wear and "cupping" on the outside of the tires. Once I replaced the original continental contitrac tires with general tires and did a 4-wheel alignment the problem was resolved and it was nice and quiet. However, at about 30K miles on the new tires the noise began again. Despite rotating tires every 5K the problem persists and the tires/road noise returned. I really like this vehicle but this noise just kills me.
