I run about 65 psi up front and 62 psi in rear right now, 75 psi when I tow heavy. I would run a 55/53 psi in my 2005 cause it gave a better ride and I never had the TPMS warnings to worry about. The 2015 and the Cognito lift I have rides better, so I don't notice the higher pressure and it's probably better for mileage and tread wear.

LOL I'm deleted obviously and not an LML but an LMM which is a lighter vehicle to begin with and I get about 11MPG in town which is most of my driving. Not lifted just 33's.

A pound of rotating mass is equal to 5# in the bed. So the 300# more is more like 1500#. The effect is greater the more starting and stopping you do.

I get 15 on 265's, I think I got better mileage before mods but when I had a lift and 35" toyo MT
