Anyone have any idea what this combo is good for mpg -wise? truck is a 3500 Crew Cab dually 2wd. Assume gears to be 4:10 ( I am unsure)....

I realize that this is not going to get great gas mileage, but how BAD will it be? :hmm:

Well, my single wheel 2500HD with nv4500 and 4.10s gets between 10 and 13 city and 15-16 highway mpg. The dual wheels might lessen the mileage just a little.

Thanks for the input...if it at least gets around 14 it could be livable. Unless gas keeps climbing....
