22.5" suspension and tire pressure??

My buddy has a 2003 f-350 dually. Just had 22.5's installed wrapped with Contintenal HDR 255/70/22.5. He wants to know how much tire pressure to run in these tires b/c the recommended 110psi is way to much the ride is stiff. He currently is running about 70 psi and it is better but still little stiff. He also is looking for shocks. He wants Bilstiens but cannot find them for his application. he has a 2.5" leveling pro-comp kit in it. So basically he wants to know

How much air pressure should he run in the tires??
What brand/model shocks to get and from were??

Any input would help out a lot thank you.

I tried the 22.5s on my 06 Dually with 265/70r22.5 Michelin's and even at 55 psi front and 50 psi in the rear. it still rode like crap..got rid of them and went to a set of 19.5 direct fits from Brentz Wheels.
