Hi...
Probably doing the same thing on my 16XRB
This site is a great way to compare actual sizes when considering changes.

Of course, different brands will have slightly different specs in a given size, but not enough to matter.
So going from a 185/80-13 to a 205/75-14 should be about 3/4" wider and about 1 3/8" taller, overall.
