Was running Goodyear Duratracs and was seeing right around 17-18 MPG highway. Replaced them with Nitto Ridgegrapplers in the same size and am now seeing 16-17 MPG. Both tires were/are run between 28-30 PSI on Hostile MOAB wheels and the Jeep has had a teraflex puck leveling kit for the last 5 years. It's an '08 JKUR Auto and without a tuner to adjust shift points the MPG and drivability suffered pretty badly.
