Just curious what people are running in their 10ply's???? I originally had my 295/55/20 STT Pro's aired up to 35psi like the door says but it seemed to be a little on the low side...rode great! however when I let of the gas it was like my e-brake was on slightly and quickly slowed my truck down so I can only imagine how much my ecoboost is having to work overtime now lol. A buddy of mine told me to go 42-45psi....so I thought I'd leave it up for debate on here. Thanks in advance guys.

I am running 40 psi. That is the setting of my TPMS.

I have 275-65-20 and run 50 psi. they seem good at that. I'm not sure what the best is though.

I prefer 40-46psi much like what your buddy said. I run 42psi and it rides great without feeling too spongey. Had it at 48psi, but felt like it road too rough and noticed the centers of the tire were starting to wear more than the outside edge.

45psi with my tire specs below.

Chalk test will tell you what pressure to run so that the tires wear as evenly as they can.

42 to 44 psi cold is usually a good place to start for daily driving. Each truck and tire will have an optimum psi for a good ride and fuel economy. It may take awhile to find that spot!! Believe me I've had many sets of LT rated 10 ply tires to experiment on in the past!
