I have a 2006 Dodge 1500 SLT Reg Cab 4.7L 4X4 with Nitto Terra Grapplers. 45K on the tires, they need replacing.(275X60X20) Need new tires. Looking at Cooper Discoverer AT3, General Grabber AT2. Since I bought my Polaris Ranger a few years ago I hardly drive off road anymore. About one week of snow driving a year is it. Before the Nittos I had Goodrich Long Trails and lost two mpg after the switch. Experiences?
