Re: 33's

What you're tryin to tell us is that you have got 24MPG in you powerstroke?

I wouldn't change any tire sizes if you're getting such great mileage because it will go down if you go bigger.

Re: 33's

Wow I must have missed the boat with the secret to getting great mileage.... best recorded mileage ever was on stock tires, strictly highway and that was 17.3

With my current setup I see 15-15.5 all day long.

Re: 33's

with my level kit and 33's i got about 17 in the city and saw 24+ a few times on the highway, but averaged about 23-23 mostly

I now have 35's and have hardly even noticed the mileage drop if there even is any. i haven't calcualted it yet, but miles per tank hasn't decreased.....

2005 F-250 FX4 CC
bought it, then changed it.

Re: 33's

How fast are you all driving to get 24mpg?
