I have 83,000 miles on my '06 Sonata LX and replaced a set of Continentals Pro Contact tires. These tires are by far, the best tires I have had on this car in the seven years I have owned it. It originally came with Michelens and I then had Sumotomo tires that cupped and replaced them with the Continentals. Always have a four wheel alignment done after the tires are mounted. Good investment. Have you tires balanced, rotated and alignment checked every 5,000 to 6,000 miles. I keep 32 psi in the tires, checked and done in the morning when the tires are the coolest and not hot from driving.
