I seen the general consensus has been on here that 35" tires hurt gas mileage which is obvious, but I went from a lowered truck with 30" terra grappers to lifting that truck effectively 5" in the front and 7" in the back with the tire increase (5100 kit with 2" lift springs in the rear giving the truck a 2-3" lift over stock) and used 295/70/18 mickey thompson baja MTZ tires. The tire size has been entered into the computer via alpha obd and speedpo is correct. I havent done extensive highway driving but my general MPG has gone from flutuating between 22 and 24mpg to between 16 and 17. even with 3.92 gears the trans downshifts more often and now often takes fluttering the pedal to upshift compared to before. I am actually thinking of going to 33" tires dispite the 34s looking so much better on the truck I also have been looking at more conservative tread and lighter tires in hopes that there might be a set of 33.5 or larger all terrains out there that might help regain some of the trucks driving manners.
As far as how the suspension upgrades went the 5100s ride much better than what I had when I bought the truck used a couple months ago.
