THe 275/65R20 are stock tire size for an F-250. stock for the F-150 with the 20" option is 275/55R20.
I need to do spark plugs also. it seems spark plugs are a big topic of debate for this truck also. And forget about Motor Oils that Debate will rage on forever about whos' is better.

i recently bought a used 2010 XLT 5.4L 4x4 SuperCrew. From the get go it just has gotten the Highway gas mileage I was expecting. I'm currently getting around 13MPG on the highway @ posted speed limits from 70 to 75 mph. Am i doomed to keep getting this MPG or do you'll think this is alittle low.
i know from the looks of things with the truck that the pervious owners had done some Mods and removed them. Mainly simple stuff like aftermarket stereo and removed start. but they removed them which I can only figure that they were probably having problems with them. This is as far I'm going to assume on that. but if they would install stuff like that and take it off before trading it in. makes me wonder whatelse they did to it.
any ideas on why my MPG is a littler lower then desired of like 16 on the highway or maybe alittle better.
oh also i noticed that the tires on the truck are 275/65R20 the sticker on the doors says the tire size should be 275/55R20. so once again i dont know if the truck came like this or if they got these and replaced the factory tires and size, possible never having the comp recalibrated for the little bit bigger tire size.

Your Tires Im running same size I went from stock Pirelli's 275/55/20 = 31.9" to 275/65/20 BFG Alterrian T/A LT M&S and they are only 5lbs heavier then my stock ones were per tire. and for the size I wrote BFG, they told me to run 40psi to get best mpg, traction and wear and ride
Good luck with the calibration Dealer tried didn't work, they just done a TSB on the tranny and which improved it, to the point its better then it was when New. and the calibration changed from 3-4Km's off to 1-2 Km's off now and mpg improved 1-2 depanding how much I have my foot into its.....
Here is a pick my truck in front my buddies stock FX4 with the 34.1" tires
Stock new at dealer in 2012
