You can use varying widths as long as the rotating diameter is equal or very close. I admit 1.1% will be pushing it, and you could run 265/35/18 on all 4 to be safe if you wanted. I assumed with a widebody that you wanted thicker tires on the back -- and it would be close (but I admit possible) if you wanted to run 275/35/18 tires on the front.
