I have a 2017 Eco diesel big horn with the 3.55 rear.. I am getting some Nitto Ridge Grapplers in the stock 275/60 R20. Does anyone out here run them on their rig? Wondering what the noise and any MPG loss will be.I drive 15 miles a day on the interstate to work and tow a 4200lb boat on the weekends. I got stuck the other weekend getting to the boat ramp on a dirt gravel road with the stock tires. Needing some input on them. Before you say BFG KO2 I am not a BFG fan.
