What is the latest and greatest rear tire for the RT? I have not been riding as much as I used to so I am out of the game so to speak. I am starting to ride more this year and it is time for a new rear tire. I was just wondering what people are using nowadays. I know they improved the stock Kenda a bit, but from what I read, it still does not last. I like the Kendas they used for the fronts and still have plenty of tread left (I have not quite 20k on the spyder). Thanks.
