My buddy has a 2003 <nobr style="color: darkgreen; font-weight: normal; font-size: 100%;" id="itxt_nobr_1_0">f-350</nobr> 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 <nobr style="color: darkgreen; font-weight: normal; font-size: 100%;" id="itxt_nobr_2_0">tires</nobr>??
and
What brand/model shocks to get and from were??

Any input would help out a lot thank you.

 

Has he tried the grease pencil method?

Sorry for not answering you question, but how about a picture?

 

I think I'd run around 80% of max PSI, more or less. I'll also say that a G or H-rated tire just won't ride car like (if that's what he's looking for).
