Re: Fuel milage
Your fuel consumption is not as bad as you think.....
If you put on bigger tires, they'll have a larger rolling radius; if you don't reprogram the computer to compensate, your odometer and speedometer will both register low, in direct proportion to the change in rolling radius.
The larger tires will have more rolling resistance than the smaller ones, so there will be some increase in fuel consumption. The lift won't affect your city mileage, but it will hurt you on the highway; somewhere between 1/2 and 1 mpg.
