I live in a rain forest on the north tip of Vancouver Island and spend alot of time ridng in the rain. I had Dunlop tires on my 2008 Sportster, and found them to be quite adiquate in all conditions. My new Super Glide Custom has the Michelin Scorcher's and they are exceptional!! Through rain and anything else you can throw at them. I draw the line at riding in snow, but had no choice last winter, when I rode through wet slush. (higher elevation surprise slush storm) I was tentative and kept the speed down but was able to ride it out, without any adventures. (about 20 kilometers) Unbeleivable traction!!! The Dunlops were good but I find the Michelins excellent!! - Carry on
