Truck towing tire pressure?
I found a chart tellig me what tire pressures I should use on my F350 for given weights. My front should be 50PSI and my rears should be 40PSI unloaded and with a 2800# fifth wheel load added to my 3200# unloaded weight it should be 70#PSI. This is deviding the axle weight by two but I have a dually so do I devide by four which make the rear tire pressure 40# recommended. Does anyone change tire pressure to tow or do they make all tires the same to handle all conditions?
