I definitely think I can do better but I can't keep my foot out of it. The truck has about 30k on now, and I have not had a tank where I didn't floor it at least once.

I think I've had the tires for about a month now. Im not sure what the winter blend is or does for the truck but it is definitely a possibility? I think the main impact was the weight increase over the stock tires are 40.4 lbs per, and the BFG's are 57.7 lbs per. Another factor is I haven't re-calibrated the speedometer yet.
