I'm entering my first winter of bike commuting and so far so good, but I'm concerned about tires. I had a pair of Kenda block 8s on my commuter bike and they were so flat-prone that I switched to a pair of Bonetrager Race Lite Hard Cases. The good news is: flat free and much better roll, but I'm worried that they my be slick in the rain. I have also heard that the tire doesn't really matter so long as you are on pavement (in other words, all tires slide when wet, so ride slower and less lean in the turn). I did nearly biff it over leaves but am thinking all tires will slide in the leaves. Are all tires created equal when it comes to the rain and wet leaves?
