While several factors affect the towing capacity of a 2015 Ford F-250, the general maximum range is between 12,400 and 14,000 pounds for a conventional trailer. A four-wheel drive F-250 with a 6.2-liter gasoline V-8 and 3.73 axle ratio has the lowest towing ratio.
For maximum towing ability, consumers should select the 6.7-liter diesel engine with the 3.5 or 3.73 gear ratio. Towing a gooseneck trailer instead of a conventional one also affects the weight capacity. With this option, the maximum towing range of the F-250 is between 12,300 and 16,500 pounds. To determine the actual limits for a particular truck, operators should check their vehicle owner's manual.
