This is my post from December 14 when I got Michelin Pilot Super Sport tires as replacement:
There are at least 4 threads on this forum on the defective Hankook tires. The Hankook problem is the Ventus S1 noble2 tires have a double layer of spirally wrapped nylon. It's this use of nylon vs polyamide that cause the tires to flat spot in as little as a few hours. Tirerack has a discussion of this at

I drive about 3 miles to work. Well each way I get a rough ride due to the tires flatspotting. I live in South Florida so cold weather has little to do with it. Once the tires heat up on the expressway, problem is resolved if your wheels are balanced correctly while the tires are hot.
I complained to the dealer. The service manager was willing to swap my tires for a new set on another Genesis. However, he tried five different Genesis vehicles and all of them had the same flat spot problem. He put in a request to Hyundai to replace my tires. After talking to Tire Rack I suggested that they use Michelin Pilot Sport A/S 3 times. I had my fingers crossed as to whether Hyundai would even do anything let alone upgrade to the Michelin tires.
Much to my surprise the service manager called me two weeks later and said he could replace the Hankooks with Michelin tires. I was very happy.
What was even a bigger surprise is that they replaced them with Michelin Pilot Super Sport(Max Performance Summer). This is a fantastic tire. The ride and handling are noticeably better and the tires are quieter.
I had a short-term lease on a 2013 Mercedes-Benz S550 which had the same Michelin tires. I leased the 2015 Genesis 5.0 as a replacement. Up until now I really missed the Mercedes-Benz ride. These new tires help the Genesis to almost equal the Mercedes ride.
Bottom line: if you are having a problem with the tires call your dealer, make an appointment and demand that they be replaced. Go with the A/S 3 tires if you live up north. I feel real good about the Genesis and Hyundai as they stepped up to the plate and went beyond the call of duty to make this replacement.
Here is what Tire Rack has to say about these tires:
The Pilot Super Sport is Michelin's Max Performance Summer tire initially introduced as Original Equipment on several of the world's most sophisticated performance vehicles, including the exclusive limited edition Ferrari 599 GTO, Ferrari's fastest road car ever. Developed for drivers who care about how tire technology enhances their vehicle's performance and safety, Pilot Super Sport tires expand the Max Performance Summer tire performance envelope by delivering durability, handling and traction while increasing tread life. These tires are king of the hill in the Max Performance Summer category
