a rock crawlin’ dude
I don’t do any real off roading in the ram (tow rig) but I run ~40psi cold for street useTrying to - extreme left end of the chart I've got is 35PSI - gives ~2300# ea to cover passengers and any cargo I'm likely to have, just have to air up before towing. For some reason it scares me to go that low on the truck, but other threads seem to match (https://hdrams.com/forum/index.php?threads/tire-pressure-unloaded.16120/post-340726) so I was gonne start stepping-down pressure.
@Rockcrawlindude I see you run this size tire - what are your normal pressures when not rock crawling?
40psi on my tires is good for 2500lb per corner so it’s perfect for the front of my rig as you can see below 5000lb is about good for my front axle.
I could run less in the rears but I just run 40 all around and the ride is fine. When towing I bump the rears up to 50 psi to stiffen the sidewalls up.
My 2500 weight with normal cargo and no trailer as you see here.
Hope this helps
