Does anyone know if anyone makes a 31 x 10.5 tire for 16" rims?
I have a 01 D 5.9L and I want to get some new tires.
Also, does anyone have any comments on doing to shackle torsion bar lift to maybe fit a 32" tire?

You don't have to lift to fit 32" tires. I know many D owners that have done the lift successfully with no long term problems. I don't like the stiffer ride in front so elected not to do it.
