Old thread, but just had to comment. I bought my Duster this past November and drove it 150 miles home. It had a bad shimmy over 60 MPH. Took it to a tire shop to have them look at the tires. The back tires were dated 1992, but they did not look bad! The tire tech said he had never seen that before. So glad they did not fail on my drive home. Sure rides nicely with new rear tires!
