New Gears
I'm going to venture a guess at a few things here:
1- Your truck does not have many miles on it yet, fuel mileage will improve as you rack up the miles on the odometer.
2- The addition of the 315's decreased mileage a few MPG...
3- The Quadzilla is just too much fun not to put to good use!

Right again. My tires alone weigh 77 lbs each and measure 13" wide at the treads.
Oh yeah...
That's CRAZY!! I drive like a bat out of hell with wheels and tires that each weigh more than most grown men and it's cold, AND I do city driving about 30% of the time now and I am still getting 16.5 MPG. Pure highway I can almost crack 20. Oh yeah, I just turned 4000 miles.
