it actually depends on how you drive. if you go to larger tires and don't change gears and drive in town or do a lot of stop and go then your mileage will drop.
if you drive highway all the time and are rarely driving in town then your mileage will go up.

I'm with Jete's, mine dropped 1 - 1.5. Don't forget to check your speedo, 60 mph between mile markers should equal 1 mile, so add back the difference when checking mpg.:)

Expect a mileage drop period, with bigger tires, it will NOT increase in town OR on the highway. Even a minimal tire size increase will reduce your mileage. Expect at least 2 MPG less.

Before I regeared I had better mileage and Leathernuts still hasn't regeared and he gets better mileage than he did stock.
This is for about 85% highway driving over 65mph and no stop and go traffic.

In town though or if you are a 50/50 driver you will loose your mileage and you will be mashing on the skinny pedal more to get your anchor moving.

The flipside though is if you regear you will be mashing on the skinny pedal kickin' the buts of civics and dakotas...:devil:
