13-17...depending on speed/style. 13 is more common now than anything with the devil USLD in the tank.

So far 15mpg in the city, but should improve when I get out and do more highway....
I was getting 16mpg before the lift/tires...

Should improve if I can stay out of the skinny pedal too

I lost a solid two miles per gallon, (about 12 city 15 highway) going from 33s to 37s. I have not had my speedo recalibrated, just did my lift and 37s this past weekend. I think if you stay with a 35X12.50 you may be slightly better off than with a 37X13.50, but I don't think it will be a huge difference.

I would be happy to post pics, but I can't even get the pictures from the camera to the computer (go ahead laugh, but its true). I will see what I can do, I am going to do the fender rolling mod in the next week or so, cause they do rub a little, okay a lot, but I like the wide tire look. Some guys do not care for it, but to each their own. I will try to get pics on in the next week or so, but I may need some help.

It is not bad enough to keep me from driving it, but it is annoying. Really it is just sharp turning. I think it will be fine once they roll the fenders a little more. I know that it is a lot of tire with that lift, but all in all, I am happy with the way it turned out. If I had went with a 8" rim, or maybe a little more backspacing it would have been fine, but I like the tire and wheel combo enough to make it work. I know "redrock" is running the same wheel as me with a 6" superlift and 36" tires and his rubs too, so going to a six wouldn't have solved anything.
