I purchased these tires in January 2012 to replace the stock Kumho Solus tires that only had 23,000 miles but hummed like a hummer! Unbearable! After 10,000 these tires are still very quiet, the ride is smooth, and the tread looks brand new. Yes, I get some spinout on wet roads, but I think that is more a result of the lightness of this Sonata and the torque the put on most cars these days - they want to jackrabbit off the line. I am a little concerned reading reviews of drivers with more miles on these tires. Noise seems to be a recurring theme. Crossing fingers!
