These came stock on my 2013 Genesis Coupe. Have had them for 16 months, 20000 miles. The tires have about 40% tread remaining, which is right where they should be considering that most Potenzas only have a treadlife of 26000-28000 miles. I use them primarily for daily highway/interstate travel to and from work with a little city driving. Great performance on dry roads, routinely takes cloverleaf on-ramps at 70mph, no slipping with or without traction and stability control. Not much of a loss of performance in light rain, but hydroplanes easily above 65mph in hard rain and across shallow water. It never snows here, but roads do ice occasionally in late winter, ice performance is decent as long as you keep it under 35mph. All-in-all these are good performance tires that trade treadlife for better traction. If you got your sports car to get groceries and look pretty setting in the drive way, then go ahead and replace these with an 80,000 mile tire. But if you are like me and enjoy driving your sports car like a sports car, then I would recommend keeping these tires and changing them every 25,000 miles.
