Just curious about what to expect... I am test fitting a 35x12.5R18 General Grabber AT2 Tuesday, and if all is good, will probably be fitted with them by Saturday. They don't have in stock and would only get one before I commit to buy.

So how would you expect these type tires would affect mpg? It isn't a big deal really, I just didn't want to be shocked that my avg mpg back and forth to work drops from current 16-17mpg to 10 or something lol. After all, I did install a supercharger that requires premium to my Mustang with little regard to mpg... but it still gets 25 on highway, so the F150 can't compete!

Of course depending on fit, may end up with 33's, much difference in mpg between 35 and 33?

Do all king ranches have the 5.4? In any case, expect to lose between 3-5 mpgs and a slightly noticeable loss of power (slightly less with the bigger engine). If you want to keep your speedometer and odometer accurate, make sure to have the computer reflashed for the larger tire size, as you lose between 2 and 10 mph with the new tires, depending on your speed. Good luck and enjoy your new meat.

I think all are 5.4, mine is. I also have a Gryphon so will be able to adjust for tire size.

Here's my stock fx4 with 35s and a leveling kit.

You'll probably be around 14 or so. Which if you have a mustang that gets 25, I would use that for the daily driver, and leave the truck at home for when you need a truck.

Here is a picture of mine with 2.5'' front/1'' block in the rear. I have 35/12.5/R18(pro comp xtreme all terrain) on my stock rims. The only problem I have is rubbing at full lock otherwise love and 35's. Don't follow the gas enough to care, sorry.

My f150 is running 305/60/18 and it gets about 15 mpg with a bed cover.

Getting excited, the test fit went fine, no rubbing at all. They only had the one tire, should have other three by Friday, planning a Saturday morning install.

Sorry for crappy cell phone pic
