2011 F350 Super Crew 4x2 unloaded ride quality

^Rear tires he meant. And 35-40 is even good in back when empty. Front should/will be 50-60 all the time with a diesel, but less with a gasser.
This question tells me you've never driven a 1 ton truck before? If that's what you're planning on getting, why not drive one yourself and for, your own opinion?

Also, how do you know you need 80psi in the tires? Do you know what your axle weights will be? You may be fine with less pressure all the time in the rear tires...or may need higher pressures.
