I have thougt the same thing. but pretty sure that I could not fit them on my truck unless I modify the rear fenders to almost the top of the bed rail.
as you can see I am pretty close. I dont think I could move it any higher and make it look right. as it is now I have around 1" of clearance on the top of the fender.
here are some figures on tire size.
225/75/16=29.29
265/35/22=29.30
225/60/16=26.63
245/40/19=26.72
looks like to me there is just over 2 1/2" difference. I think it could be done, but the fenders would have to be at the top of the bed rail. I think the front would not be a problem as long as the lugs clear.
