Got Kumho tires from tire rack and had alignment and installation done by Rogers AR Firestone store, tire racks recommended installers. A few weeks later I had to go back in for another alignment. 5 months later and the tires are cupping and making a loud noise. The only thing Firestone or Tirerack will do is ship tires into kumho for inspection which would mean I would have to buy two more tires in the meantime. Firestone rep also said 9 out of 10 Kumho wont do anything anyway.
