You COULD trim and bumpstop to run those, but is a lot of tire for stock suspension.
Stock rims are 7" and those tires will bulge, but you CAN run them. It is no different than people running 12.5" tires on an 8" rim - very common and preferred wheeling to avoid separating a bead if aired down to low PSI.
The issue with stock rims and those tires is that they will rub the lower control arms when turning hard. You can turn out the steering stops at the expense of turning radius, but those are pretty tall for stock backspacing.
You could run spacers or swap for less backspacing rims, but then the lack of lift would be even more noticeable as you push the tires out and then the fender will want to rub even more.
A small lift of 2-3" is a good combo with a bit of trimming and proper bumpstopping for 32's.
