17 inch wheel psi

I have 17 inch wheels on my 06 PSD. The door sticker says they should be at 75 psi both front and rear. At that psi the truck rides like a brick unloaded. What is everyone else running their tires at?

I ran 265/70R17s at full pressure with the 6k front springs, and I had no complaints.

The 17" 245/75 R17 Conti's on my 2010 F250 ride pretty rough too at 75psi. I keep thinking about airing them down some but I keep forgetting to look up at what pressure the TPM starts squeaking. I get enough of that from the other seat! It still rides better than my 3/4 ton Dodge at 40psi front and rear. Those Michelin XPS A/S with three steel belts ride hard as rocks at any pressure. That or it was the truck...

I run Michelin LTX A/T2 tires in size LT275/70R18E. I run 65 psi when not hauling/towing and the ride is acceptable for a F350.

I have 37inch BFG AT's. I am running 50 in front and 45 in the rear when not hauling anything. I adjusted the air by looking at the contact patch. thats on a crew cab 7.3.
