I had a meeting recently with the head man at Hankook. He asked what tires a ran on my C6. When I told him Firestone run flats he told me that Hankook would be bringing a new run flat to the US in sizes for the C6. If true it will give us a nice option to run flats by Firestone, Goodyear and Michelin.
I told him that I would need a tester set to do a true comparison.
