Default gas mileage with larger tires

Hey... I'm thinking about buying a 00-02 4x4 v6 dakota 5spd. My question is: what gas mileage do you guys with the v6 engine and a 5spd get? And also - have any of you with the same truck gone from stock tires to 33x12.5, and what gas mileage do you get now?

expect a 10% drop, if you drive normally. MPG in signature, on stock size (235...) 15's.

If you are that concerned with gas mileage don't even bother with a Dakota! If you do, I'd skip right over the V6 and get a V8. My V6 sucks nearly as much gas down as a V8. I'd probably get better mpg with a V8 since it'd be working less!

I did a 3" body and still had to cut part a small part of the bumper off you can not tell I even did it

I was using gps in my truck and and my speedo is off at 65-77 mpg I get 14.5mpg

My 2001 QC 5 speed with 4.7 V-8 gets 17mpg hwy with 31x10.5's. I have cold air intake, dual exhaust and a set of headers waiting to go on (which might improve mileage even more). Might I suggest the 4.7? More power and better sound in my opinion.
