I think some of your math may be off. 481/39.67= 12.12 mpg. You also said your truck is stock? So your odometer has not been adjusted for the bigger tires? You have actually traveled MORE km than your odometer shows, so your mileage is actually better. The really cold weather, and more ethanol in the fuel isn't doing you any favors either. Just curious how many liters of fuel your burned? By my math 33x3.78=124.74. And 776.4/124.74=6.22km/L. If it makes you feel better, I'm getting about 5.5 right now. I personally don't think you have anything to worry about.
