Black smoke is fuel you are only getting part of the work out of.
Wider tires catch more air and roll harder, lower MPG.
Anything that raises the truck up makes it catch more air, lower MPG.
Taller tires induce speedo error, the odometer shows less miles than you actually covered, apparent lower MPG than it actually is.
As for more black smoke than you used to see, have you changed anything?
Injectors getting weak causes them to pop early, advances the timing which can cause more black smoke.
How many miles on them?
Have you changed the air filter recently?
How long since the fuel filter was changed?
How many miles on the IP?

well i would have to say that because i noticed it get harder on fuel on a 13 hour or so drive to where im living now is there anyway that i could be burning more fuel because im way more north from where i was living??
but also i have changed a few things after a while of living here like i put a k&n air filter on but have run it without the filter to see if that was a problem
went from a bfg m/t to a way more meaty micky thompson m/t
now a straight pipe
no idea on how long they or the pump has been in the truck for the pump has a sticker on it and a diesel shop said it looked like it has had something done to it but i have owned the truck for about 9 or 10 months now and fuel filter was changed a few months ago but will put a new one on when i get the new injecters in

The only thing being farther north that should affect fuel MPG would be more warm up time.
What kind of temps are you seeing at night?
Another thought would be the fuel blend if night time temps are close to freezing.
As temps drop, the fuel suppliers start blending #1 diesel or kerosene with the #2 to lower the chances of fuel gelling.
