I have a 2022 F-250 Tremor. I put a 3.5' Carli back country lift on it with the leaf springs, high mount steering stabilizer, and torsion sway bar and it seemed to improve the ride quality pretty dramatically compared to the stock tremor suspension. That was about a year ago. I just put new 37x12.5x18 Nitto Ridge Grapplers on the truck and it seems like it is riding worse than it was on the factory wheels (35x11.5x18 GY all terrains). I run the tires at about 45 psi in the front and 40 psi in the back, which is about the same as the old tires. I thought the extra two inches of tire would help smooth out some of the smaller bumps but it seems like the opposite is true. Any thoughts or opinions are appreciated.
Like the others reported is probably the Nitto's have stiffer sidewalls. I've noticed a harsher ride on my truck with these same tires and my truck is running factory suspension.
Been watching this forum for a good while, I am older. However it seems al of the ride quality issues have lifted, leveled, or suspension modifications.
And it's then I have issues. Just my oldschool 2 cents.

I talked to a few people with rough country, etc lifts and they generally tell me they got the lift to look cool but also to get better shocks and tires to ride better. Then they get surprised when riding in my bone stock F250. They asked me how it rides so well and if I got so-and-so kit, I just tell them the truth: I adjust the psi according to load on each axle, and they look visibly confused and it dawned on me that they were riding around on 70+ psi all the time before they threw money at the problem.
Lower the tire pressure 5lbs and see if it rides any better -- it should. You can always do a chalk test to make sure you didn't lower the psi too much. IIRC, I settled on 10 lbs less than what your running on the 37/12.5/20's RG's, on my 2018, and didn't have any unusual wear.
I just found this article on Carli's website and they say to run 37's at 40psi front, 35 rear. That sounds like it lines up with what you are running. I'm going to give it a shot this evening. Thanks

i run my 37's at 50 all around when towing, now that the truck is no longer daily towing i'm gonna drop down to the carli recommended spec. They feel plush already compared to the worn out 35's that were at 65psi.
I run 35 psi all around when not pulling or loaded on my NITTO's on my 2020F250. If I have a load I bump it up in the rear. Your NITTO's are 1 inch wider than your previous tires and need less pressure to carry the same load. The Carli Rear springs made a big improvement for me.
Make sure that they are balanced properly because they are a heavy tire.
