I will try 55 PSI all around and see how that feels. Somehow, I don't think that's going to be the answer. The feeling is very similar when it's unloaded with higher tire PSI. 40 PSI all around when unloaded feels very similar to the former P rated tires, but as soon as I have 50psi unloaded the truck feels like it's swaying (fishtailing). The steering is more sensitive. Now with the 5er hooked up, I can feel when the big rigs pass more than witht he previous tires as well as the crosswinds. A little too much sway for my comfort. I will play with the air pressure a little bit, and if that doesn't work, I will try to swap out the tires. I can't believe this isn't more of a common problem. Maybe it's with the Nittos only.
