This Fall has been fairly rainy. I've ridden in lots of light and heavy rain and I can tell you that my Bontrager Hard Case (slicks) work great. If you go over a metal grade or manhole cover, be super careful because they will get super slick. There isn't a tire out there that can protect you on that kind of surface. There will be some differences between various tires, but I've found the Hard Case tires to be infinitely better than my Bontrager Invert Select tires I had on the bike before (those had some light tread). With the Insert select tires, the tread picked up all the little bits of road grime and the little rocks would get pushed through the tire and I'g get s flat... no such problesm with the Hard Case (slicks). Last night I finally had to put the snow tires on. We have only a few inches of snow on the ground, and the road are clear, but only 3 miles south of here they got almost 3 feet of snow (you've got to love the crazyness of how locallized lake effect snow can be). There were a few icy pathes here and there. The irony is that with the deep knobs on the tread on my Nokia W106, I feel a lot less secure. The tires squirm a lot more and in the rain I can notice less traction. Once you hit some ice or snow, the studs and deep tread are VERY welcome. For fun I've tried ridding in my street with slicks in the snow, and it was impossible. With the tread I can power my way through 6" of snow (not easy, but it can work).
She Schwalbe's are an excellent all around tire. You won't be setting any speed or light weight records, but they are tough and will work well in all but serious Winter weather.
Happy riding,
André
