S Davis, How much air do you run unloaded? I have about 2500 miles on mine with the camper on the truck. Maybe 300 miles unloaded....hate how these things handle unloaded...maybe I'm running too much air. Think I have 60psi in the front and 75 in the rear. I do have the option of swapping wheels and tires when the camper is in storage...but what a pain.
Don't run any less than 70PSI in the 19.5s. In fact, the load tables start at 75PSI on most of them so even 70 is a bit of a risk. You can/will damage the sidewalls. I run mine at 80/95, and that's unfortunately (I think) the price you pay to get that much extra stability/ capacity.
I wouldn't say that my 19.5" tires had as much individual effect on ride quality as my air bags or StableLoads individually did. But with all three together I can't stand it anymore and decided to go full air ride. What are you running on your suspension?

19.5's on Rickson steel wheels are very heavy, increasing unsprung weight, reducing braking performance, acceleration, and mileage. They increase safety margin due to increased carry capacity. Very resistant to punctures.
1st set of 19.5's I used were Goodyear G-622 RSD Rge G. A bit noisy on paved roads and stone throwers on gravel roads (as in smash out the rear fender liners). The truck also displayed "duck and dive" lateral following of parallel cracks and ruts due to the stiff sidewalls. The GY tires were just ok on snow and ice. Not much bite for lifting a trailer if parking when warm on packed snow. OK in mud. Kind of disappointed. They belong on the back of a 550/5500 with a steel flatbed and the tunes cranked up in the cab... not on a 4x4 SRW... took them off they are in the shed should put them up for sale...
I bought a set of lightly used take off Michelin XZE Rge F "smooth" tires. The ducky handling still present, but less. Noticebly smoother ride, quiet, and ...here goes... much better traction on snow and ice. The grooves have zig zags molded in them and little ridge dealies in the bottom of the groove which bite on snow... and then the Michelin compound is stickier on ice... I wouldn't have believed it either...
And then... pulling a loaded 18000lb gooseneck stock trailer over a muddy 2 track into a pasture after a rain... the Dodge scratches it's way up a little jump up hill that a GMC diesel dually with "all season" 16in tires spun out on with a 5 cows smaller load, requiring a pull (despite frantic "spinning up" of his wheels)...
We all stood an looked at those muddy "smooth" tires and said "that's just not right..."
Anyhow the Ricksons and 19.5's are off the truck waiting to go on a 8 bolt 2 axle trailer.
There are better options available in 18in and even 17in tires now for recreational trucks.
Unless you travel smooth, non rutted and maintained roads. Rge F 19.5's worked really nice in those conditions for me.
What about 18" and 17" wheels? There are tires rated for 4k, but the wheels need to be at least rated for 4k also to make sense. Are there many or any rated for this in that size?
