The Marathon is a Load Range "E" tire and is rated at 3420 lbs. All of the LT tires otherwise mentioned are rated at 3042 lbs or therabouts.

That is higher than any of the LT tires being recommended as replacement and "is" higher than the Marathons. It is also rated at 75 mph as are most of the LT tires, where the Marathon is only rated to 65 mph as are all ST tires.
All the other tires mentioned in this thread are Load Range "E" and are 10 ply rated. It seems a lot of owners have switched to some of the recommended tires and have had no problems, but you are reducing the weight carrying capacity per tire from the Marathon and considerably from the G614.
