If the G614's are only 1 inch larger in diameter, although the Goodyear site says they are the same as the Marathons, that means they will only be 1 inch closer between the tires, and only 1/2 inch higher into the wheel opening. Pretty sure there is at least that much extra room for the tires on these rigs. They are also a bit wider than the Marathons, but so far on our rig, the wheel opening trim is still there.
