I decided to try these tires from Western Bike Works, which are custom from Vredestein for them, but the logo is upside down.
Take a look:
Vredestein Gran Fondo TriComp at WesternBikeworks
Doesn't seem to make any sense, unless you're supposed to look at the logo for tire pressure, etc., from above.
I've never seen a tire with a logo in this direction.
