Came as OEM on 2010 Hyundai Genesis Coupe 2.0T base. Was not expecting much life but kept them at 33-35 psi and rotated every 10K miles which on the turbo Gen Coupe is every other oil change (side to side rotation per owner's manual since front and rear rims are different widths) The rears hit the wear bars at a little over 54K miles with very flat wear, no cupping, no block noise (a little more carcass noise but not annoying), no balance issues or steering wheel shake. Did very well in a majority highway driving southwest desert environment. I realize other reviews are pretty negative but they did pretty well for me. One thing with them is they aren't directional like most other higher end tires for this rim size which allows them to be rotated side to side.
