I know most people that have K61 love them and I understand the difference between the K58, K61, K66, and the K66 Snowtex. My question is deals with the fact that we don't all live in the dry and arid biome that is Southern California. I am interested in tires that can handle the year round erratic behavior of Central Kansas. We have everything from 115°F with 0% humidity in the summers, to monsoonish weather in the Fall and Spring, and finally sub 0°F winters with sporadic snow storms. Which is the best year round? Has someone tried each one? Once in the Summer months here I will go with the K61 or Pirreli SL 36. I would like to have a good all around tire for the fall, winter, spring months. This isn't limited to Heidenau tires but I am guessing that most here that will be bias to them so that is just what I presented.
Remember this is for the fall, winter, and spring!
