You could run a 25c Pasela in back and 28c in front. When I go large on two of my bikes, I run 38c Paselas in front and 35c in back. 25c in the back of my fix gear and whatever tire happens to be on the front rim (usually 27c but its so old I can no longer red the lable). The style police may show up and haul me away but they haven't yet.
