I have a 2009 Supercrew F150 with the 4.6 V8. I am considering jumping up to 33s. I have it leveled right now. If i were to jump up in size do you have any idea on the loss of gas mileage ? Or other problems I may run into ?

Gas mileage will be little to none. I lost 1-1.5 mpg going to 35's with my 4.6, you shouldn't lose much. 33's make very little difference, I know my fathers stock king ranch's tires (06 I think) off the showroom floor were 32's. Your speedo will be a bit off, take it to a dealer and have it corrected.

I have a 04 f150 with a 4.6 single cab 4x4 and I have a 3 inch body lift with 34s and you can't tell a power difference until you come up on a big hill going down the hwy and I lose 5 mph. And my truck gets decent gas mileage about the same as my dads 05 5.4

I have an 07 and stock tires on it were 32" i don't think you will see much difference

Also depends on your gears.
I have 35's with my 4.6l with 3.55 gears and there was about a 2-3mpg drop and its a slug but with the 4.10 gears I am getting it should preform way better and I will gain about 1-2 mpg back. But with you 33's you should have no trouble at all and your power/mpg loss should be minimal.

I just got 33's with my 4.6 and haven't noticed any loss of power, don't know about mpg's yet

I have run 33's - 35's now and did notice 2-3 mpg loss but picked up a tuner and recalibrated everything. I average 14.5 now and have been since the tuner
