Tire size for optimum fuel mileage
Ok guys, I have got an 06 F-250 4x4 crew cab with a short bed. It's got the 6.0L in it. I have recently rebuilt this truck from the ground up. Someone had wrecked it and hit every inch of this truck. BUT what I am wondering is this: I drive close to 200-300 miles every day for work ( and yes I do have a little honda I drive for good fuel mileage) but some days require me to haul trailers or go back into the mountains. So I need to be getting the best possible fuel mileage out of this thing. I am going to be putting an AFE stage 2 intake on it. Cut the muffler and run a straight pipe through it.
What I need help with is deciding on what size tire to run. I am deliberating between a 265 or 285. I will most likely be purchasing a fairly "roadish" tire. The majority of my driving will be in between 65mph-75mph. Which tire will provide the best mpg and put me in the right RPM range for this truck? Also I have 373 gears on the truck. If anyones got any suggestions on good solid tires that will last let me know! I usually am buying buck shots but I need to start being practical now with fuel prices the way they are.
