I'd suggest that you look at the broader picture. It's not just about the load that the tires can take. The tires transfer their load to another surface.

That means that they have the potential to overload the contact surface. Your potential to get stuck on soft surfaces goes up the more highly your tires are loaded and the softer the surface is.
There are many other factors (benefits) to larger tires/wheels but that is beyond the scope of this discussion.

Only if the tires were close to being max weight, mine are not, I have something around a extra 5500 pounds carrying weight on tires over my gross weight of 20,500lbs weight.
As to surface contact I don't see a issue with a 19.5 at these weights, maybe 30,000 plus lbs but not 20,500 lbs.
