    I'm thinking about buying a lifted 2010 Silverado(4.8L). It's got a 4in Suspension Lift, Nitto 295/55 R20 Tires, 20in Premium Wheels

    Any idea what MPG I'd be looking at?

    thank you

    Depends, did the person you're buying from re-program the computer for the new tire height?

    My 2011 5.3L V8 gets about 17-18 mpg in the city and 20-21 highway driving like a senior. My 2001 ranger 4.0 V6 gets 16 city and 18-19 highway that's why I am better off with a full size truck.

    I really do not care about the mpg on the truck because it is a business necessity. I guess what I am trying to say is we buy a truck because we need it.

    Probably around 13-14 mpg. The large tires and the lift are fuel economy killers.

    Same here.

    I had a 2001 Explorer Sport Trac (Explorer with a 4ft bed) and the best I ever got was 20MPG. My 2008 Silverado weighed ~800 lbs more than the Sport Trac, had ~115 more HP and got better fuel economy.

    My 2008 and my 2013 have the 275 55 R20 tires and gets way better than 13-14. My guess is the lift completely ruins the aerodynamics of the vehicle.
