The tire label should be alinged with the stem of the tube, for common sense. If you get a flat, and can find the hole in the tube, you can align the tube with the tire (since everytime its the same way) The hole will be in 1 of the two sides.
Rim labels face drive side for mechanic reasons. Everything is on the drive side, so if everything can be read/seen from that side it is easier to work with, especially in race mode.
