20" wheel / 275/60/20 tire / total tire diameter 33" - will it rub

Hi, I tried to find this on other posts, forgive if a duplicate. I have 2003 CA 1500 4WD with body panels, I do not believe there is a lift kit but there sure is plenty of room between top of tire and fender. I recall when I bought it used they said it had an off road package. Currently has 275 70 16 (30.6" tire diameter) . at rentawheel.com they recommend for a 20" wheel to use 275/55/20 tire, total tire diameter = 31.9" . I'd like to go to 275/60/20 tire diameter = 33". I've turned my current wheel full lock and measured, it does seem the 33" will work without rubbing but naturally this is not the same as a full wheel on vehicle test. I realize there are other factors to consider but I'm simply seeking guidance if a 33" diameter tire using the same width (275) as my current stock size, will rub at all or rub at full lock.

my 33s on 20s with a level kit fit but I had to trim a lot...and after a week or 2 the rubbing came back. only after I put the body lift I had no more rubbing
