I am running 2005-ish (forget the exact year) Hummer H2 rims, so they are factory GM. Tires are BF Goodrich All Terrain KO2 315/70R17.
You can see the bottom of the front blue plastic on the bumper has been trimmed to clear the tires when turning. Not pictured is the cab seam which just gets folded flat behind the tire to clear when turning. That's all the trimming that's needed for this combo.
Rear tires are easily inside the factory fender flares. Front tires are a little iffy, depending on how your law is written. But you could put on slightly larger aftermarket flares without it looking weird if you had to.
Hope this helps!
