Hi, Many years ago I played w/ upsizing the (tire) width on a set of tires I was replacing on my travel trailer >>> BIG MISTAKE. What I learned was that I should have checked the inflated tire diameter of the new size before I bought and mounted (and eventually returned!) the replacement tires. The new size had clearance issues (loaded suspension travel) within the wheel well. If it were me I would downsize to a 205 (if clearance is seen to be an issue) and up the tire rating (IE. B to C, or C to D >> depending on what load rating you currently have).
