So far I am loving these tires. I had a set of Goodyears with not many miles on them, and the front tires started to split where the tread meets the sidewalls (factory defect, but useless Goodyear didn't give a d*mn). I had to buy new tires and was always happy with the Michelin MXV4+ tires, but I found these Kumho's for $60 less and the same ratings (Better in some categories). My first few trips with these tires made me very happy I got them. They are super quiet, very comfortable. Their traction is top notch. They look great too. Its too early to tell how they affect mileage and how the treadwear is, I will update again with more miles on them. But compared to the old Goodyears, they were nearly $100 less per tire, they have much better traction and speed ratings, and the wear rating is better too. I got the Goodyears for the quite ride and the traction and I must say these Kumho tires out perform the Goodyears. I would very much recommend these tires, you can't beat the price and they perform above and beyond any other tire at this price, even better than some tires that are twice as expensive.
