			And the numbers are all nice and everything, but different tire manufacturers tires will spec out to different widths even if they are considered the same size.  A Sumitomo 315/35/17 is actually quite a bit narrower than a Goodyear 315/35/17, it's also a heck of a lot cheaper!  And a 255/50/16 will measure out almost as wide as a 275/40/17 again depending on the brand.
