I have a 2006 Big Horn 4x4 with the hemi. I just found I need to replace an outer tie rod (only 39,000 miles on truck!) so I am going to level it with the Bilstein 5100s. I am wanting to go with Nitto TG or Goodyear Duratracs in 275/65/20. I am curious what this will do to my mpg. Does anyone have a similar set up? What did it do to your fuel economy? Pics would also be nice of your trucks with similar set ups.
