After tossing around different tires I have decided to stick with the Kumho... For me it just plain works. It handles very well and even though it is a run flat it offers a bit softer ride than the stock tire.
I did think I would get a bit more mileage out of the Kumho, but I am ok with 18,000 seeing that the edges are what are warn the most. I may need to bump up the PSI back to 35. 32 might have been a bit soft and added to the quick edge wear.
