Here's a pic of my Schwalbe Marathon Winter tires in action. They are covered with road grime in this picture (hence they are less reflective than my pannier's piping) but they are still quite reflective.



For nicer weather I use the above-mentioned Michelin Pilot City tires. I would have bought Schwalbe Marathons since I am so impressed with the Winter version, but the Michelins were half the price and they have a "slicker" tread pattern. So far I am very pleased with them. BTW - if you are considering the Michelins, and you want puncture protection as well as a reflective strip, make sure you choose the Pilot City over the City tires.
