Truck Dually Wheels
After looking at one ton trucks with dually wheels, I prefer the one ton trucks with single rear wheels. What would I be giving up not getting the dually wheels?
Forum Discussion
How many people driving a dually realize that they were NOT developed to improve stability? The original purpose was to reduce ground pressure.
Oil field workers in West Texas and New Mexico found that the rear wheels of their pickups, when loaded with welding machines and other equipment, would break through the crust on the desert sand and bog down. Before cell phones and/or affordable two-way radio this sometimes brought about a long walk to get somebody to come pull them out.
Duals cut the rear ground pressure in half and reduced the break-through.
If you draw an overturning force triangle with the load apex at the trailer pin; the base right angle at the ground under the center of the rear axle; and the support apex at the center of the rear wheel(s) the difference in moment resistance between single and dual is almost negligible. If you look into the mind of the guy with the dually, the difference is enormous!
Half again as much rubber on the ground for braking is a different matter.
(Yes, I have used both to pull the same trailer and have gone back to SRW, but with a long bed. JMHO)
