Ride Quality Difference Between 17s and 20s on 2nd Gen?

The stock 17 inch wheels on my truck weigh 23.5lbs each. The 275/70/17's (OEM size) weigh 49lbs each. For a total of 72.5lbs.
The stock 20" chrome clad wheels off a newer ram weight roughly 35lbs. That means you'd have to find a tire that only weighs 37.5lbs to have an equal weight setup, lighter still to have a lighter setup. For reference, a 275/60r20 BFG KO2 (OEM size for the wheel) weighs 55lbs. A much less aggressive Continental Terraincontact weights 43lbs...still at least 5.5lbs over the weight limit.
Also, E load is a designation that indicates the number of plys in an LT tire. You can't compare E load vs LT because they are different designations. LT stands for "Light Truck" tires, and indicates a tire with higher gauge cords, often deeper tread, and just an overall more rugged design. One could make the case to purchase P metric tires for ride quality, but you didn't mention making such a transition.
Given that you don't appear to know the terminology difference between load rating and tire construction type, and given that I can't find any examples of 20" tires that weigh under 40lbs, I am inclined to be skeptical of your claims.

So how exactly do you add 3 inches to a wheel's diameter, make it out of the steel (heavier than aluminum), with a similar design that actually has wider spokes, slap plastic covers on them...but lose 1/3 of the mass?

We're talking about 2 different styles then mine is aluminum no covers with chrome inserts

Not as thick. I weighed them when I went to beadlocks because I wanted the same weight. Personally Fjgtx is the most knowledgeable guy on tires and rims. This is pretty basic. Less sidewall = harsher ride. Stiffer tire = harsher ride

I can't find an image of OEM ram wheels that are aluminum with chrome inserts anywhere. Care to share what you're talking about?

Yep, was clear in my initial reply in #5 that my data was 2500 (3/4 ton) components. Perhaps look at the aftermarket to see what they have in 20s for weight.... or you might look at the 1500 dedicated spare steel 20s. I sold a couple of those 1/2 ton 20" steel spares I had to someone wanted to run them on all 4 corners. Just make sure the decorative holes match on them, they have at least two different designs.
