What's going to give you more tread contact, 275's on 9" wide wheels or 255's on 9.5" wheels?

find the rim width that specific tire is meant for (depends on the aspect ratio) then if you are going bigger (like its meant for a 9 inch but you put on a 9.5) instead of X contact patch, it will have approximately X + .2 inch contact patch, same way if you go down a half inch, it should lose about .2 of contact patch
