bad gas mileage?

Remember that with 285 size tires, you're going farther than your odometer indicates (about 7%) so add that in before you calculate your mileage. So you've actually gone 50.3 miles. Even still, 50 miles on a quarter tank is pretty low. Mine is usually indicating 80-100 miles at the quarter tank mark (I also have 285 mud terrains). Try and keep your rpms below 2000 for the best mileage.

 

im getting between 12-15 in the city and 17-19 on the freeway. i want better gas mileage but i ddont want to take off my lift/rims/tires.
