This winter mix has hit me too...only getting about 14. You increased your tire by an inch..the rolling resistance beyond that with different tread pattern/compound affects it too. I am lifted with 265-75-16...
Good point on the tire size.
If I use the tire calculator is tells me my speed (hence my mileage) is understated by about 5%. If I take the 856 miles and do the math I get actual miles of about 898. This puts the mileage at 14.2 MPG.

Here in Kona we can buy non ethanol gas at the boat harbor. When the ethanol gas first came out it screwed up every ones outboard motors including mine (900 bucks worth) So last year out of curiosity I drove my landcruiser for two months on the non ethanol gas and got two mi per gallon more (12mi with ethanol vs 14 mi without) Unfortunately they charge you 25% more not two put the ethanol in the gas
Hmm over here im running mine on 95 unleaded.
about 130 to fill it up and doesnt seem to last very long.
im running a 265/75/16 tyre as well.
i havent actualy tested mine for how much k's i get per tank etc.
but yesterday i put in $80 was i near the empty line but no light.
ive reset the counter, im gonna drive to the light comes on then record my k's etc
i put in around 44 litres i think at a cost of $1.80 something a litre.
will report back once ive got my empty line on.
mods wise, no cat converter and a custom muffler simular to the pv2. but not straight through by the sounds of it.
A few things that might be affecting your gas....
Your altitude. (CO?) No pro on this, but it must come in to play somehow.
Your driving style. Accelerating 4k lbs from s stop takes a toll.
Mods. Bigger tires/lift create more drag too.
Winter gas boils faster/sooner so it burns off faster. Cold start-ups REALLY take advantage of this at the cost of eating even more. I recommend block heaters in this case. Cold engines run harder to get to running temp, so they burn a HELL OF A LOT of fuel just idling. Typically, cars only need about 30 secs of start idle in the cold to be up and going, just don't hammer it. Let those fluids flow at a comfy pace.
