Dennis,
Some very experienced riders helped me with this same question. While pipedr is right in the regards that you might not even notice a difference, for different tires you might. Tires designed for higher mileage tend to be a little harder when cold. In the case of my ME 880s, I do notice them being a little harder when I first get on the bike in the morning on my way to work. That being said, they have never slipped, and within a mile of riding they are warm to the touch. Unless you are getting on the bike after it has been sitting over night and immediately starting the twisties right then and there you should be fine. If for some reason that is the case, I would ride a couple of miles not only to warm up the tires, but the engine as well before you start pushing it through the Tail of the Dragon. Have fun and ride safe.
