I looked at that when my 05 Dually needed tires and decided to stay with the original size because of tire to tire clearance. What I did was put 215s on the rear and 245/70s on the front (both had the same OD) gave me a little more rubber on the front to support the Duramax weight. As noted, you could add a spacer between the wheels to increase the distance, but I would think that it might increase the stress on the axle bearings, but then again if it wasn't much it would probably be OK.
