The Hankooks replaced the OEM runflats that came with the vehicle. Let me tell you - what an improvement in comfort and noise. The ride is still firm, but not as harsh. It rides very smooth and the cabin is so quiet I don't have to turn up the volume on my radio. I only have about 1,000 miles on them, so I will see how these tires wear over time. Do check your alignment as mine was way off in the rear. This will add many miles to the life of the tires.
