depends on if you want a tall skinny tire or a wide mudder type, my suggestion is find a tire shop willing to work with you and put the largest size he suggests on the front and check for turning clearance the wider tires will hi sooner then the narrower ones also under the truck there's torsion bars that can be cranked in and this will raise the truck some
265 75 16
you should be able to run a 33 on stock wheels with no problem
replace a window lift motor for a 2002 gmc sierra?
2.5 inches is the largest lift you can get safely without having to fabricate something for your forward differential.
Not without headaches p235 75r15 is your largest candidate without a lift, especially if you've got tired springs
No, of course not.
It depens on how much lift is on it, but without a lift you should comfortably be able to fit 33x8 sized tires on them with little or no rubbing.
without a lift 265. maybe 285
285/70/16 without any lift changes!
