Tire Pressure
Curious what pressure/size tire everyone is running.
I myself am running 285 75 16 LT @ 65 pounds front and rear Thinking of dropping them down to 50 pounds
With a full heavy load I would be tempted to run max pressure.
With the combined experience here, perhaps we can all benefit?

I run 285/75R16's at 65 which is max tire pressure. Max pressure for my truck mostly empty provides the best tread wear and life. I don't notice much of a ride difference with I drop to 55 psi and I won't run any lower than that.

There's a lot of difference in opinion on this matter. With 235/85 16s I used to run the door sticker specs - 55 front 80 rear. 80 is way too rough for daily driving. I swithced to 55 psi all around and it was just fine. Great tread wear, smooth enough ride, and good mileage. I stuck with that after bumping up to 265/75 16s. In trying to troubleshoot my terrible mileage problem I bumped them up to 65 psi all around this week. I can definitely tell a difference in ride quality after only like 75 miles. It's rougher but if it helps my mileage then so be it. Some people put a stripe of white shoe polish, finger nail paint, soapstone, etc across their tread and then adjust the pressure til it wears evenly. Sounds pretty logical to me.
