wheel size

[tonkadave]

Ok I'm looking to swap out my GM 12 Bolt for a 14 Bolt out of a late model GM truck or SUV. I want to stick with the 6 lug and I'm keep it full with. The question I'm putting out there is will a 15 inch wheel fit over the disk brakes or will I have to go with 16 or 17 inch wheels? I'm in Iraq so I can't do any fitment of wheels and such. I know that the late model trucks and SUV's come with 16 inch wheels. Any info. would be great.
