I just got back from a trip up north (1500 miles)
Stock 97 with 170K, minus 2nd and 3rd row seats and seat belts, minus subwoofer, but with a medium load that I think puts me back in the stock weight category. I'm running Michelin Cross Country 275/70/16 which I believe is the same size as stock, and I measured them at 31.4". When new they were probably over 32".
On the highway getting up there I averaged 16 mpg with the AC on. On the way back I averaged almost 20 (no AC) until I hit the Grapevine. After the Grapevine, I averaged 18. Both times there was a good cross wind.
For the trip which included city driving, dirt roads, mountain passes, I averaged about 15. Not too bad. But my 80 runs real good. It's real smooth and quiet. And unless the shocks were replaced at some point, my stock ride is comfy, stiff, and feels pretty new.
I also noticed that I'm only getting 18.5 gallons or so per fill up. I usually get about 170 miles until the halfway point on the gauge. When I'm all highway I get almost 200 and sometimes even better. For a full tank, when I'm on E (which apparently means I have around 6.5 gallons in reserve) I get somewhere around 340 all highway and around 300 mixed.
These are just rough figures and estimates and they were derived using numbers from the gas station (gallons) and the trip meter (miles).
EDIT: highway speeds are usually around 70-75.

Because they top the tank totally full maybe?
I do notice a difference in Baja also not much. When they fill up it is very full and the highway speeds are lower.
35's RTT loaded very heavy 10.5 to 13.2 average city and highway.
OffRoad in deep sand washes less than 4 mpg
Slight grade makes a large change. But always averages out in the 10.5 to 13.2 range. I have tried being very light footed many times and never get more than another mile to mile and a half per gallon.
