Gday everyone! About 2 months ago I did the stupid thing and buy before researching and now I'm paying the price. I bought a set of yokohama geolandar G015. Size I'm running is 285/75r17 10 ply E rated. I've dropped it down to 27psi when they warmed up and still drives bad.
They just don't absorb bumps, bad roads and pot holes very well.

I'm considering going to Falken wildpeak at3w 275/70r17 6 ply C rated tire which I'm sure should drive more comfortable. My question is, is there anything out there more soft in a LT tire that anyone can recommend? Or will that be soft enough? I've changed to evo Plush ride coils from ome and it made an improvement, but I still think the tires can be improved

 

Try same diameter tires on 15" rims. There are rims that fit a JK. The ride will be plush.

 

I love how my Falken at3w in 255/80-17 ride. They are E rated but ride very smooth and quiet. I run 30 psi or so. They are 33’s. I also run cooper st maxx’s in 315/70-17 on another set of rims so I switch them often. The coopers are d rated and are good to but not as smooth or quiet as the falken s.

 

I just bought my third set of Goodyear AT Adventures, 285/70-17. For reference, my Jeep weighs between 5000 and 5300 lbs. Although these tires are E rated, they ride soft at ~30 PSI on the highway. At 35 they still ride fine, just firmer. By comparison, they are a pretty light tire. Only 6 pounds more than the smaller stock 255/75-17 KM tires.

Here's my method for predicting how hard or soft a tire will be, independent of the ply rating: Check the weight and compare with similar sizes. Light weight tires tend to be softer, less tough, and feel best on a lighter vehicle -- But also might tend to get reviews of mushy feeling on a heavier rigs even though running much higher pressures. For the most part, we are running tires meant primarily for the pickup truck market, so it's a lot easier to get an annoyingly firm tire than a mushy felling one.

 

I had that geolander model tire in the stock JKU size for 17" wheels. I liked them and had no issues like you describe. Perhaps mine were C rather than E sidewalls.
