Conti's and several other manufacturers put the same labeling on both sides of the tire. While fore is correct in stating that tread for narrow, high pressure road tires is pretty useless, the "arrow" created by the herring bone pattern on conti's and other brands should point in the direction of travel for both tires. You'll notice that tires that do have a label on only one side will have this orientation when the tire is mounted with the label on the drive-side.
