The Avon's I have on my 07 RK have been great. The rear tire has 16,000 miles on it, and it is at 2mm, and if I wasn't going on a long trip, I would run it down to 1mm. The front tire, I just changed, and it had 21K on it. I highly recommend Avon's because of the load rating, and they are very good in the rain.
