and for more reference... when I had my 285's on my 2000 the error was 8.7%, with the 295's it went up to 9.3% and the 295s were a 33.4" tire so you may actually be farther off than you think.

I have a 2002 stock rig, 35,000 miles
no addatives
auto tranny
4.10 rear end
4x4
I was getting 18. mpg average before my lift pump went. After the dealer installed the replacement now I'm averaging about 16! Anyone else lose mileage after pump replacement? I never calculate my mileage by hand, I only use the trucks computer, I wonder what some of you see as far as difference between what the truck calculates and by hand.

I'm curious too mbaz. What difference are y'all seeing between hand calc. and the computer. I just bought mine '06 4X4 2500. Everything on it is stock. I have about 2000 mi. I've been using about 8-10 oz. of PS white bottle in it. I'm getting about 14 or so on the computer. Most of my driving is 60%city\40%highway right now.
