Tow Vehicle Tire Pressure

I was wondering what most of you run your TV tire pressure at? I currently have Goodyear LT tires that have a max PSI of 80 but am currently running around 40. Should I add more tire pressure when I am under load especially when towing my TT and all loaded up with bikes, camping gear, firewood and whatever else I can throw back there? Thanks for your thoughts.

Mine are rated at 80 as well, when I am not towing, I run them at 50.

So you guys have been adding pressure when preparing for a trip... I assume do this before you start while tires are cool?

My truck shows 80 psi - rear, and 65 psi - front. Max tire pressure (sidewall) shows 80 psi. That's what's in them... Not sure why you would run half that. Seems low...

I thought so too. But, that's what my tires were coming from the dealer? So I just assumed it was OK. It seems from previous posts here though that some people do run at a lower pressure when not under load. I would suspect it would be for better ride quality... and possibly proper performance depending on the utility/job we are using our vehicles for at the time. I guess?? Maybe??

I run what it says on the door sticker, 60 front, 70 rear (tires are rated for 80), regardless of towing or not. Don't see a reason to over-complicate things, or worse, take off and forget you are 20 psi short.

Well if there is any chance of forgetting I will ... I can see your point of setting it then forgetting it.
