Depends upon thetotal wt of the combo. along with number of tires, tire width, frontal area, type of frontal/wind resistance, surface of the road you are on, along with the grade you are goingup, and total speed including the wind you are going against!
Example, a 15K rig with 70# of FA needs 105 hp to go 60 mph, change that out to 90#, you now need 135 hp to go 60 mph. ALong with an additional 45hp per 1% grade you wish to hold 60 mph at! Change that out to 69 mph against a 30 mph head wind.......a LOT o hp is needed!
So to honestly answer your question, it depends! we are not disCUSSing the diaper variety either!
