FE Freak!
I run 315/75/16s with 4.10 gears and a c6 and get 14-16 or so. Thats with no Moose Pump and turned the screw all the way in.
JD, can you go and measure how wide those tires of yours are at the tread? I got 235/85-16s now, and to say I got a tendency to sink in soft terrain would be an understatement - I was thinking of the 265/75-16s as they would be wider, but the overall tire diameter would be the same as what I got now.
I'd have thought it would be more. I usually hear of 20+ empty with those early Cummins motors....
In Dodge's probably. Don't know what they weigh, but they LOOK lighter.
