8mpg pulling a loaded trailer,

Gas or diesel?

 

[Jedt71]

Diesel
I was pulling a 9x32 ft trailer with 20 unassembled Porta Jones and 10 hand wash stations

I'm seeing 16.9 on the dash with the Mopar lift and Nitto RG 35s. This is 95% city driving. Speedo is calibrated with a Tazer.

I'd say you're seeing better than average for your setup. Driving habits also makes huge different. 75 mph on the freeway is going to really suck it down compared to 60. Plus 75mph with a lift and big tires kind of scares me.

I get 20+ on I35 between Austin and Ft. Worth where the average speed limit is 75. Unless I’m driving into a headwind.

28 on the highway empty and I did hit 30mpg one time driving down to Florida

That's running 80 mph

Haha I'm at 31psi cold and i can't imagine how 55 cold would feels like. That's nearing the max rated when it's hot. It must have contact patch of 10" wide tires.

Bounce down the road like a basketball.

Max is 65#
It's an E rated tire on a 5k# vehicle
I run E rated on all my trucks and air up on the road.
Only exception is our SUVs, then I soften the ride with lower pressure.

Air pressure definitely makes a difference in MPG and our drag coefficients are quite high.

Pot holes are worse at lower pressure

Road noise is higher at higher pressure

PS, it's never cold here, we have a Sub-Tropic Lattitude and Attitude

That's what this was like on 36x12.50x15 Bias-Ply TSL Swampers

It was "The Wanderer" and your seat belt wouldn't get tight enough even with pucker factor applied to go over 60 mph.

The JT actually rides better than you think aired up, I like the more connected feel it gives than the aired down squishy feel
