I currently have some Gladiator X comp 35x12.50x20 but looks like I will be doing alot more driving with the job now, no towing just more highway driving, and thinking about putting the 275/65/20 Nitto Terra Grappler G2 XL tire on that is only 47lbs. I have 20x10 wheels...does anyone know how this would look or have pics? I definitely think it would help my mileage.
