(or, if you're Conti, coming up with your own freakish width standard that bears no resemblance to the actual size. Remember, never let Continental back you into a tight parking space. "Loads of room, about 12 inches" crunch "Oh, sorry, we measure our inches differently to everyone else, actually it was only about 6")
