The owner's manual notes that, for a 4x2, the Gross Axle Weighting Rating (GAWR) is up to 2550 and 2750 pounds at the front and rear, respectively. Total Gross Vehicle Weighting Rating (GVWR) is up to 4880 pounds. Therefore, the worst case is 2750 pounds over two wheels....or 1375 pounds per wheel. That would work out to a 92 load rating. Any tire with a 92 rating or higher should be satisfactory from a loading standpoint, right?
