33'' vs 35'' Tires

I cant decide wether i want to just get a 2.5'' leveling kit and 33's or the 6'' kit and get 35''s. how much of a difference in gas mileage is there between the 2 sizes? this will be on an 04 f150 5.4L. if i'm only gonna loose a couple miles per gallon i might just go with the 6''. gas is a huge factor for me.

You don't tell us what truck you have. The 35" should fit with the leveling kit if you have a 04-06 4x4 on stock rims. Many on here have this set-up. If gas is a huge issue then I would leave is stock.

Yes you did tell us what truck. As you can see from the rest of my spelling I was a little side tracked. It sounded to me like you wanted to go with 33s or 35s? Then the way you phrased the question it sounded like you thought you needed a lift to clear 35s. I have no idea how the stock rims interact with a suspension lift. If you are calling a the leveling kit a suspension lift then yes you can you your stock rims. Look at BalogUKs truck. There are others on this board running 35s with only a 2 or 2.5 leveling kit. The only problem with the 35s is the chance for irregular and premature tire wear from a 12.5 wide tire on the narrow stock rim. The 33s are 12.5 also, but it seems we have seen less reports of irregular tire wear with the 33s vs. the 35s. I would stick with an AT. The tire will last longer and not be as much of a drain on the gas tank. The BFG AT KOs are a great tire. Do a search you will find a few guys with pictures that have them with the leveling kit. Hope this helps.

As long as you either get your speedo/odo recalibrated for the larger tires or compute your MPG's with the corrected miles traveled, then you should not see too much a drop, but you will drop a mpg or two....

The 35's will be heavier then the 33's and they will be heavier then the stock tire so you will have to overcome that. Plus, they are probably wider, so there will be a little more rolling resistence to overcome.

If you keep the stock gears, you might see a bigger drop in city mpg then hwy because you will be 'bogging' the engine more from a stop with the taller tires.

If you only have 3.55 gears, then I would only go to the 33's. You might get away with the 35's with the 3.73 gears, but it'll still 'bog' pretty bad IMO...
